:00:18. > :00:24.Hello and welcome to the One Show with Matt Baker. And Alex Jones.
:00:25. > :00:28.Tonight's guest was in esteemed company last night with Her Majesty
:00:29. > :00:36.the Queen and Dame Helen Mirren. Tonight he is slumming it with us,
:00:37. > :00:41.it is a Sir David Attenborough! Good evening, Sir David. Great to
:00:42. > :00:48.have you here. We have a brilliant picture of you. Caught between two
:00:49. > :00:54.Queens, so to speak. So to speak! Was it a good evening? Yes, very
:00:55. > :01:02.good, and evening in praise and celebration of the Royal Academy of
:01:03. > :01:09.come my brother is president. -- the Royal Academy of Dramatic Arts, of
:01:10. > :01:16.which my brother is president. He is not well, so I was representing him.
:01:17. > :01:22.This was 1958, with Prince Charles at ten years old, and Princess Anne
:01:23. > :01:28.at eight. And that cockatoo was a cockatoo which I traded with pygmies
:01:29. > :01:34.in the centre of New Guinea, and we had been marching for... I don't
:01:35. > :01:38.know, about eight or nine days through unexplored mountains, and we
:01:39. > :01:43.met these pygmies. And one of them had this on his shoulder, and I
:01:44. > :01:51.fancied myself as long John Silver, and I traded it for, I think it was
:01:52. > :01:55.two cakes of salt. Big cakes of salt, which is what we were trading
:01:56. > :02:02.with. And the pygmies had done something to one of her wings so she
:02:03. > :02:06.couldn't fly. Her name was Cocky, very original. I had it for a long
:02:07. > :02:13.time, I brought it back to my home, and she was a lovely bird. But she
:02:14. > :02:16.was a coward. We used to put her out on the wisteria at the back of the
:02:17. > :02:23.house, and when a butterfly would come up, she would go... And she had
:02:24. > :02:29.screamed. I mean, she did drive the neighbours nuts. I was fond of her.
:02:30. > :02:33.The neighbours had more than they could take. Eventually, I discovered
:02:34. > :02:40.there was a lady who was more crazy about cockatoos than I was, and it
:02:41. > :02:45.went on to her. And that lady, I know she has died since then, but
:02:46. > :02:51.cockatoos can live for 100 years, a long time. So I do not know where
:02:52. > :02:58.Copy is now, I am afraid. It is a lovely picture, take it with you. We
:02:59. > :03:03.might need the frame! All the photos that people keep sending in! On we
:03:04. > :03:06.go, when you buy a property, certain checks are carried out by your
:03:07. > :03:11.solicitor to make sure the land you are buying is safe, secure and debt
:03:12. > :03:15.free. But for the visitors of a small town on the outskirts of
:03:16. > :03:17.Glasgow, things have not turned out as planned and they have been left
:03:18. > :03:27.with whopping bills to pay through no fault of their own. Tony has been
:03:28. > :03:36.to see how much each house pose. -- owes.
:03:37. > :03:52.My house, ?43,000. This house, ?14,000. ?60,000, ?25,000, ?69,000.
:03:53. > :03:57.?109,000. This is one of 13 homeowners in Blanefield facing
:03:58. > :04:04.staggering bills to remove contamination from their land. We
:04:05. > :04:15.are not at fault, but we are being asked to basics and rebound ?33,000.
:04:16. > :04:25.I have personally a ?43,000 bill. -- 630 ?3000. Howdy you sleep at night?
:04:26. > :04:29.-- how do you. With difficulty. Through no fault of their own, many
:04:30. > :04:34.residents here face financial ruin thanks to the legacy of a factory
:04:35. > :04:39.built down there back in the 19th century.
:04:40. > :04:45.The picturesque village of Blanefield was home to a huge calico
:04:46. > :04:50.printing works which, at its peak, employed up to 500 men, women and
:04:51. > :04:54.children. Mary is a local historian. What kind of things did
:04:55. > :05:02.they do in the factory? It was calico cloth, they were bleached,
:05:03. > :05:08.watched, bleached. It was quite a process. The big problem was the
:05:09. > :05:19.refuse from the operation. It was put into the Blaine here. It killed
:05:20. > :05:24.the fish and vegetation. 100 years later, it still contaminates the
:05:25. > :05:30.land in the village. It only came to light when in 2012, under recent
:05:31. > :05:33.law, Stirling Council tested the soil and found potentially dangerous
:05:34. > :05:39.levels of arsenic and lead that they say has to be cleaned up. But the
:05:40. > :05:42.firms who bought the print works and the developers who build the homes
:05:43. > :05:51.have long since vanished into the mists of time. With no-one left to
:05:52. > :05:55.take responsibility for the contamination, UK law says
:05:56. > :06:02.homeowners must pay. Martin is one of the people facing ruin. How much
:06:03. > :06:07.will this cost you? The estimated bill, including the landfill tax,
:06:08. > :06:11.will be ?69,000. In terms of our ability to pay, we have no ability
:06:12. > :06:16.to pay, it is a vast amount of money. If we catch everything in, we
:06:17. > :06:20.put everything into the deposit for the house, and it is virtually
:06:21. > :06:24.worthless. It is a stressful situation, for all of us, 12
:06:25. > :06:31.neighbours. Adding insult to injury is the fact that most of the costs
:06:32. > :06:35.are made up of a landfill tax. It is about 67% of the total bill, and
:06:36. > :06:39.that is administered by the Treasury. And that landfill tax was
:06:40. > :06:43.designed to be no lies people, companies, who pollute the land. It
:06:44. > :06:54.was never designed ordinary families. -- designed to Pina lies
:06:55. > :06:57.people. Money aside, the knowledge that the house is built on
:06:58. > :07:03.contaminated land has meant changes to the way that they live. Exposure
:07:04. > :07:08.to arsenic can lead to higher rates of cancer. We cannot grow fruit or
:07:09. > :07:17.vegetables. We restrict what he does out here. It is a case of shoes off
:07:18. > :07:22.at the door, wash your hands. Developed in the 1950s, the homes
:07:23. > :07:25.here were built before the 1990 Environmental Protect Act. It is
:07:26. > :07:30.only since then that developers are required by law to remediate
:07:31. > :07:36.contaminated land. Before then, there were fewer controls. There is
:07:37. > :07:40.an estimated 325,000 potentially contaminated sites in the UK, and
:07:41. > :07:44.with a greater push to build on brown field sites, should homeowners
:07:45. > :07:49.be worried? Is there anything you can do to check? The best people to
:07:50. > :07:52.speak to the local authority, who have historical data on the site and
:07:53. > :07:56.the work that has been done to develop the site. But if you are
:07:57. > :08:02.worried, speak to your surveyor to see if they can afford you
:08:03. > :08:07.additional advice. Residents here have been lobbying the UK and
:08:08. > :08:11.Scottish Governments for help. The Scottish Government will take
:08:12. > :08:15.control in 2015 of landfill tax, and they have made a commitment to look
:08:16. > :08:19.at residents affected by the tax. Ultimately, it is still in council
:08:20. > :08:25.who is responsible to ensure that the land is remediating by the
:08:26. > :08:29.landowner, and while they have pledged ?125,000 towards the final
:08:30. > :08:33.bill, the residents are facing huge bills.
:08:34. > :08:38.That is an unbelievable worry for the residents. Lucy is here now, a
:08:39. > :08:45.big percentage of the cost they have to pay out is going to go towards
:08:46. > :08:53.landfill tax. Can you explain that. Let's look at poor Fiona, the bill
:08:54. > :08:59.is over ?30,000. It only costs ?17,000 to remove the soil, but
:09:00. > :09:04.there is ?18,000 in landfill tax and then VAT. Landfill tax is basically
:09:05. > :09:08.something that we have kind of inherited, because we have always
:09:09. > :09:11.mined in the UK, we did the pits, and then we fill them with rubbish.
:09:12. > :09:17.There are lots of environmental issues around that, so the tax was
:09:18. > :09:20.for companies, really, to discourage them from throwing waste away in
:09:21. > :09:25.that way and get them to recycle and all that sort of thing. The tax goes
:09:26. > :09:29.up every year. It was never intended for people like the owner, and that
:09:30. > :09:34.is one of the tragedies of this situation. Meant for companies, not
:09:35. > :09:39.individuals. I hope the residents are watching tonight, because you
:09:40. > :09:43.have got some news. Yes, we have tracked down Danny Alexander, who
:09:44. > :09:47.was out on Treasury business today, and we asked him what he could do
:09:48. > :09:54.for the Blanefield residence, and this is what he said. So the
:09:55. > :09:58.Treasury will offer a grant of ?225,000 to help the residents deal
:09:59. > :10:02.with the problems. It is a grant, because that is the quickest way to
:10:03. > :10:07.deal with the problems, rather than tax relief, which is complicated and
:10:08. > :10:10.would take a long period of time. We now need the Scottish Government to
:10:11. > :10:13.make available a similar sum of money so we can meet all the costs
:10:14. > :10:19.required and make sure the problems are dealt with as quickly as
:10:20. > :10:23.possible. Massive news! We have not managed to tell the residence yet,
:10:24. > :10:27.so they will have their calculator is out, I am sure. This could
:10:28. > :10:33.potentially be a lifeline, because my reckoning they had 125,000 in the
:10:34. > :10:37.pot from the council, 255,000 from Danny Alexander, but we do need the
:10:38. > :10:42.Scottish Government to match that for them to clear their bill. We
:10:43. > :10:51.would like to hear from them! They are at home watching the One Show.
:10:52. > :10:55.Tomorrow, yes, fingers crossed. That would be amazing.
:10:56. > :11:00.Over the past few weeks, we have all seen how the British coastline has
:11:01. > :11:04.been ravaged by storms. But it is not all bad news, as Angellica has
:11:05. > :11:09.been finding out on the north Norfolk coast. The coastal storms
:11:10. > :11:12.have actually been helping. The beast and flooding is just the
:11:13. > :11:18.latest extreme weather events to hit the UK this winter. -- the recent.
:11:19. > :11:24.Back in December, the worst tidal flood for 60 years battered the
:11:25. > :11:32.Norfolk coastline. This stretch of beach in Norfolk was badly hit. You
:11:33. > :11:37.have to try and imagine the sea coming over and breaking through
:11:38. > :11:40.that shingle barrier, completely covering this marshland and coming
:11:41. > :11:45.all the way up here to this coastal road, where it flooded many homes
:11:46. > :11:48.and businesses. The sea broke through the shingle wall, allowing
:11:49. > :11:57.water to reach the coastal road and houses. Kevin manages the marshland,
:11:58. > :12:01.which is an important habitat for wildlife here. It caused a lot of
:12:02. > :12:06.damage to property, a lot of damage to the infrastructure. It puts salt
:12:07. > :12:10.water into the freshwater systems, so the main feeds into the marshes
:12:11. > :12:14.became completely safe line, so that causes a huge amount of damage to
:12:15. > :12:19.plants and wildlife that uses the freshwater. -- saline. This is one
:12:20. > :12:24.of the places where it punched through the shingle bank, and it is
:12:25. > :12:28.on the old Greek system that you can see from aerial photographs. This is
:12:29. > :12:33.obviously a weak point where it used to go out to sea, and that is where
:12:34. > :12:37.it reached and pushed through. Since that time, they have actually
:12:38. > :12:40.started to heal themselves, and the sea has started bringing in this
:12:41. > :12:46.material. It was a raging torrent one month ago with water completely
:12:47. > :12:50.in free exchange with the marshes and the sea. The cost to fix the
:12:51. > :12:55.gaps was estimated at ?60,000 and would have been part of the managed
:12:56. > :12:59.retreat policy for this stretch of coast. Not all local residents are
:13:00. > :13:04.happy with the policy. Peter and as you think it is important that
:13:05. > :13:13.drainage is maintained. We must keep the dikes and natural drainage clean
:13:14. > :13:18.at all times, because they must be kept clear so that any tide coming
:13:19. > :13:25.in can flow. At the moment, it cannot flow, so we are in danger of
:13:26. > :13:29.being flooded again. Do you think people will have to move from the
:13:30. > :13:38.village? I think you will see the village slowly die, yeah. I think it
:13:39. > :13:42.will slowly go. I do not think there is an easy answer to it, really. You
:13:43. > :13:49.cannot spend millions and millions on a village like this. In this
:13:50. > :13:52.case, like I said, we have been very fortunate that they have self
:13:53. > :13:56.repaired. It was a little bit of weight and see and hope, and that
:13:57. > :14:02.was the Environment Agency attitude towards it, let's wait and see, and
:14:03. > :14:06.luckily for us and for the reserve, that is what has happened, you know,
:14:07. > :14:11.a huge tonnage of shingle has been pushed back in by the sea, which
:14:12. > :14:14.would have cost hundreds of thousands of pounds to do it
:14:15. > :14:21.mechanically. Every cloud! Yeah, they were
:14:22. > :14:26.fortunate in that part of the world, but other areas have not been. Your
:14:27. > :14:34.new series, Sir David, starts tonight on Watch, it is called
:14:35. > :14:38.Natural Curiosities. You compare two animals that you would not normally
:14:39. > :14:44.put together, is that how you would describe it? That is incidental. The
:14:45. > :14:47.thing about the series, actually, is that it looks at animals sometimes
:14:48. > :14:52.from an historical point of view, how do we understand them and
:14:53. > :14:55.discover them? Sometimes it is individual animals that have
:14:56. > :15:00.extraordinary histories. And we look at all kinds of odd things, and in
:15:01. > :15:09.this particular instance, quite a recent discovery. Everybody knows, a
:15:10. > :15:11.lot of people know about the Komodo dragon, the largest lizard in the
:15:12. > :15:14.world, ten or 12 feet long. But perhaps everybody does not realise
:15:15. > :15:21.that recently there has been a scientific discovery that the Komodo
:15:22. > :15:25.dragon, females, can produce young without any help from males, virgin
:15:26. > :15:28.birth, parthenogenesis. You may say, what does that link with any
:15:29. > :15:34.other animal? Amazingly, it links with an animal that you will be
:15:35. > :15:43.familiar with if you have a garden, the greenfly. The green flies do the
:15:44. > :15:46.same thing. That is the nice thing about the series. You link it with
:15:47. > :15:52.animals that we would be familiar with. I watched that episode of
:15:53. > :15:58.virgin births with my six-year-old son, and of course, it does raise a
:15:59. > :16:03.lot of questions. But as soon as you put it into the theatre, you can go
:16:04. > :16:08.out into the garden and experience it yourself, and it becomes very
:16:09. > :16:14.real. The first time I saw a female aphid, you can look at it through
:16:15. > :16:18.the lens, because they have transparent bodies, and I could see
:16:19. > :16:23.there was a baby inside. If you have a powerful lens, you can see that
:16:24. > :16:29.inside the baby is another baby, like Russian dolls! You have three
:16:30. > :16:34.babies all in one. And they are all just like the mother. That's right.
:16:35. > :16:41.And that is why, overnight, your roses could be covered in tens of
:16:42. > :16:46.thousands of aphids, because they reproduce at that speed. Sir David,
:16:47. > :16:50.we have seen you all over the world, covering all sorts of species. What
:16:51. > :16:55.remains for you? What are you passionate about making a film about
:16:56. > :17:00.next, that maybe isn't connected to the animal world? I determine got
:17:01. > :17:05.time. I make films about things that interest me. I will be leaving for
:17:06. > :17:11.Borneo very soon, and there we will be filming a series in 3D, about
:17:12. > :17:16.flight, about how flight developed in the animal world. That flight
:17:17. > :17:21.first developed in insects, of course, in dragonflies, for about 50
:17:22. > :17:31.million years. Then you have animals that blinded, then dinosaur things,
:17:32. > :17:37.things which have skinny wings. Then you had birds, then you had bats.
:17:38. > :17:41.All of those involved over the period of prehistoric life, and that
:17:42. > :17:48.is what we are filming. A little bird told me that you are into
:17:49. > :17:56.tribal art as well. Me? Yes, I once made a series along time ago, back
:17:57. > :18:05.in the 70s, a long time ago. We had a great time. I am very interested
:18:06. > :18:10.in African sculpture and that sort of thing. If you are curious about
:18:11. > :18:15.the animal world, David Attenborough's Natural Curiosities
:18:16. > :18:21.will be on Watch to night. Now, a case of honour, fraud and deception.
:18:22. > :18:24.One in which the truth only emerged because evidence was planted at the
:18:25. > :18:29.scene of the crime. The Hebridean island of rum. It was
:18:30. > :18:35.in this peaceful wilderness that an audacious forgery was uncovered in
:18:36. > :18:43.1848, not in the world of art all publishing, but in botany. It
:18:44. > :18:48.involved hidden manuscripts and undercover missions, a very British
:18:49. > :18:53.case of fakery. The story of a respected botanist who went to a --
:18:54. > :18:59.to extreme lengths to be the first to prove a theory. Professor John
:19:00. > :19:03.Heslop Harrison was a talented botanist who had an extraordinary
:19:04. > :19:14.theory that the iron of Brom had escaped the last ice age. -- the
:19:15. > :19:19.island of Rum. All he needed to do was to prove his theory. Ian
:19:20. > :19:32.MacDonald isn't expert on Paes's plants. -- Rum's plants. He knew the
:19:33. > :19:41.area very well. He knew that Rum had a rare read -- a varied geology, and
:19:42. > :19:46.had lots of plants on it. By the 1840s, Heslop Harrison began to make
:19:47. > :19:51.a number of botanical discoveries that appeared to prove his theory.
:19:52. > :19:57.But they were so regular and so extraordinary that they began to
:19:58. > :20:00.arouse the suspicions of his peers. The botany Department of Cambridge
:20:01. > :20:07.University hatched a plan to send someone to investigate. John Raven
:20:08. > :20:12.was the perfect candidate to pose as an impressionable student on one of
:20:13. > :20:19.Heslop Harrison's field trips. This is John Raven's son. What did he
:20:20. > :20:23.think of Heslop Harrison? He would have been aware of him, because he
:20:24. > :20:28.was a well-known botanist. He would have been aware of his theories, and
:20:29. > :20:34.that is what piqued his curiosity about going to have a look at it. Do
:20:35. > :20:41.you know what his thoughts were before he set foot on Rum? He was
:20:42. > :20:47.there partly through subterfuge. He did not tell Heslop Harrison why he
:20:48. > :20:52.was there. Once Raven had arrived on Rum, he saw for himself the
:20:53. > :20:57.astonishing species who supposedly grew there. As has not Harrison
:20:58. > :21:04.toured around the island with his students, Raven noticed something
:21:05. > :21:12.extraordinary, writing later: One plant looked that it had -- looks
:21:13. > :21:17.precisely as if it had been faring -- fairly recently planted. He also
:21:18. > :21:22.noted that five plants were accompanied by weeds associated
:21:23. > :21:26.primarily with gardens. To prove his theory, Heslop Harrison needed
:21:27. > :21:31.evidence of plants that were not native to Britain. So in secret, he
:21:32. > :21:37.planted plants like this one, things that have come from places much
:21:38. > :21:41.colder than this, to prove what he genuinely believed - that Rum's
:21:42. > :21:46.plants had survived and could not have come from anywhere else. The
:21:47. > :21:53.suspicions of Cambridge University proved to be true. To find five new
:21:54. > :21:58.species to the British Isles on one hill on one island, it is a bit like
:21:59. > :22:02.you or I winning the National Lottery five times. I guess he got a
:22:03. > :22:10.little bit too ambitious, little bit too greedy. Having seen the impostor
:22:11. > :22:15.plants first-hand, Raven concluded that Heslop Harrison must have grown
:22:16. > :22:20.them in his garden. What is more, the established foreign plants on
:22:21. > :22:24.Rum suggested that Heslop Harrison had been planting these home-grown
:22:25. > :22:30.variations for years. Raven filed his report on his return to
:22:31. > :22:34.Cambridge, exposing has not Harrison is a fraud, but its contents would
:22:35. > :22:39.not come to light for another 50 years. He didn't want the report to
:22:40. > :22:48.be publicised until his Paris and had died. Why? He did not want to
:22:49. > :22:57.disgrace him. He did not want to embarrass him. In 1967, Heslop
:22:58. > :23:03.Harrison's records were quietly removed from the botanical archives.
:23:04. > :23:07.It is an extraordinary story of Jane -- of fraud, concluded in the most
:23:08. > :23:14.gentlemanly fashion. The list of the rarest wild animals
:23:15. > :23:20.cited in Britain has just come out. The pine Martin and the Golden Eagle
:23:21. > :23:27.are in the top three. You can appreciate the second one, the pine
:23:28. > :23:31.marten. Yes, you have to be extremely lucky, because it lives
:23:32. > :23:37.high up in pine trees. They are very rare. I have seen them in captivity.
:23:38. > :23:46.The One Show cameras managed once, didn't we? Mike saw them. Where was
:23:47. > :23:50.it? It was up in Scotland. Somewhere in Scotland, but we know the secret
:23:51. > :23:59.spot, so if you would like us to tell you, we can. Wild? Yes. Can you
:24:00. > :24:04.believe that one in four people have never seen a hedgehog in the wild? I
:24:05. > :24:08.am surprised about that, because many have seen them squashed flat on
:24:09. > :24:17.the road! Perhaps that doesn't count. Something happened on Sunday.
:24:18. > :24:25.Yes, the sun came out! And wasn't it nice to see it. It is always better
:24:26. > :24:28.when the sunshine is. Here is Martin with the science behind what makes
:24:29. > :24:35.sunsets and sunrises are so beautiful.
:24:36. > :24:39.It is 6:15am, and first light is breaking over the West Coast of
:24:40. > :24:44.Scotland. Why am I here at the crack of dawn? I am going to explore the
:24:45. > :24:50.science behind the sunrise and sunset. These are the times of day
:24:51. > :25:00.that photographers call the magic hour, when the landscape is bathed
:25:01. > :25:04.in colour, and landscapes -- and the skies are brilliant colours of gold
:25:05. > :25:09.and red hues. But what is going on up there is not magic, it is
:25:10. > :25:11.science. Graham McFarlane is an award-winning photographer, who
:25:12. > :25:19.specialises in shooting at dawn and dusk. That is a fabulous place.
:25:20. > :25:24.Fantastic. When you come here first thing in the morning, what are you
:25:25. > :25:27.looking for? I am looking for the castle being front lit, the sun
:25:28. > :25:33.coming up from the east behind me, picking up the detail on the castle.
:25:34. > :25:40.You get a reflection, and that lovely warm home to the castle. It
:25:41. > :25:44.picks it up against the backdrop of the mountains. At dawn, the sun
:25:45. > :25:50.lights up the clouds with subtle pinks. Oranges and golds follow as
:25:51. > :25:55.it rises above the horizon. But these are not the sun's true
:25:56. > :26:01.colours. This is a weather balloon. If I let it go, it will just go up
:26:02. > :26:06.and up and up. Eventually, it ascends to the upper reaches of the
:26:07. > :26:14.Earth's atmosphere, where a NASA photograph shows that the sun is
:26:15. > :26:19.brilliant white. But white light isn't just white. If you shine a
:26:20. > :26:23.beam of light through a prism, as Newton showed, you can split the
:26:24. > :26:29.white light into all the colours of the rainbow, each with its own
:26:30. > :26:33.wavelength. Blue light, for example, has a very short wavelength, whereas
:26:34. > :26:40.red light has a much longer wavelength. Each wavelength behaves
:26:41. > :26:44.differently when passing through our atmosphere. When we see the rising
:26:45. > :26:48.and setting sun we are mostly seeing the longer wavelengths, yellows,
:26:49. > :26:56.oranges and reds. What has happened to the blue light? The atmosphere is
:26:57. > :26:59.full of particles, gases, moisture and pollution. Imagine that the
:27:00. > :27:07.water in this fish tank is the water up -- is the atmosphere above us.
:27:08. > :27:12.This light is the sun. Blue light, with its shorter wavelength, has
:27:13. > :27:15.more energy, so it interacts with the particles more vigorously, and
:27:16. > :27:20.is more easily scattered than the rest of the spectrum. All the water
:27:21. > :27:25.has a blue tinge now, and this is why the sky is blue, because the
:27:26. > :27:30.sunlight is being scattered down, but only the blue part. It is why we
:27:31. > :27:35.see the sun as yellow. It is what remains of the white light when the
:27:36. > :27:40.blue light has been scattered by the atmosphere. As the sunsets, the sun
:27:41. > :27:45.comes in at a shallow angle, so it has to pass through more of the
:27:46. > :27:49.atmosphere, which tends to contain more particles at the end of the
:27:50. > :27:54.day, because of a build up of moisture and pollution. If I add a
:27:55. > :27:59.little bit more... As the light has to pass through more particles, more
:28:00. > :28:03.wavelengths and colours are scattered. None of the blue light
:28:04. > :28:08.campaign trek through, leaving just the oranges and reds that give us
:28:09. > :28:13.the sunset colours. You can't beat the real thing, though, which is why
:28:14. > :28:19.Graham is back at the castle, hoping for a break in the rather ominous
:28:20. > :28:25.looking clouds. What makes a particularly good sunset photo?
:28:26. > :28:30.Ideally we would have sums -- some clouds in the sky. We want some
:28:31. > :28:39.scattering of light onto the clouds. I like the silhouette. Today, we
:28:40. > :28:44.were unlucky. The cloud was too thick for a really dramatic sunset,
:28:45. > :28:49.but the spectacle of the sun going down is the most photographed of all
:28:50. > :28:54.natural events. An astronomer once said, it does no harm to the romance
:28:55. > :29:00.of a sunset to know a little bit about it. I would go further, and
:29:01. > :29:08.say it only enhances our appreciation.
:29:09. > :29:12.I would agree! Lovely pictures. That's it for tonight. David
:29:13. > :29:16.Attenborough's Natural Curiosities starts tonight at 8pm on Watch. Sir
:29:17. > :29:21.David, thank you so much for coming in. Tomorrow, the three stars of I'm
:29:22. > :29:25.Sorry I Haven't A Clue will be here. Alex is off to the Philippines for
:29:26. > :29:28.the next few days, so tomorrow I'll be joined by Gabby Logan. We will
:29:29. > :29:33.see you at 7pm.
