Might be your last chance to see the world....

Nasa has released a book of satellite images called Earth as Art, well worth a look. Most of the images are from Landsat 5 and 7, which record blue, green, and red light in the visible spectrum as well as near-infrared, mid-infrared, and thermal-infrared.

There's a free ipad app, or a free pdf download. Hardcopies can be ordered too.

Here's the link. Earth as Art

Don't leave it too long as I believe it's only going to be available for a short while.

Thanks fot the heads-up Gwyn.I will be deleting my account forthwith, and if.they try and apply the same t+c's to Facebook I will delete that account also. I wonder if Facebook are trying it.out with instagram to see public reaction before applying the same t+c's to facebook? Hopefully instagram will find itself without any users, but I doubt most people even read the t+c's on their various social media accounts.

The lens is still available.....

I woyld not want to edit images on a tablet.

Funnily enough, most times work colleagues see my 7" tablet, they are surprised how much more I can do with it than they can on their Ipad.....and its two years old.

I find it a bit of a strange comparison, Galaxy Note vs Ipad, considering the vastly different screen sizes......
I bought the original Galaxy Tab 7", and have seen no reason to upgrade. All my Apple colleagues have been through all three iterations of the Ipad. If you want to be trendy, get an Ipad. If you want something that just works, there's plenty of choice. Pictures look great on the Galaxy, a bit smaller granted, but if I wanted primarliy to use it to shoe images, I'd buy a 10" Galaxy Tab. I don't like Apple personally, so maybe I'm biased, but open-source software makes much more sense to me.

It doesn't work on this...I find Topaz Detail and Topaz Adjust do very weird things to the OOF areas. When I use either of them on shots with large areas out of focus, I use them on a seperate layer and then erase the OOF areas on that layer.

I had an Olympus E510 and wanted better low-light performance. Meanwhile my wife wanted a dslr and chose a white Km. It made sense to be using the same system so I bought a K7. It's low light performance was not fantastic, but I loved the ergonomics, so bought a K5 when they came out. I now have so many PK lenses, and like the K5 so much, that changing systems would be both expensive and pointless. I will probably get a K5 IIs soon.

The Sigma 10-20mm is a very good lens, but since I've bought a DA 15mm Ltd. I don't use it very often. The 15mm is so good, and so light, that it's become one of my most used lenses. It's also superb for IR if thats a consideration at all.

I'm a bit surprised that no one has made me an offer, especially considering the amount of views this post has had!

This lens is quite rare in PK fit (not seen one on here or ebay for over a year), and it is very light and compact considering the alternatives...plus it's very solidly built, has fast AF, and produces great results. Great lens for those who want the focal length range without the backache! As mentioned, a few cosmetic signs of wear on the lens body and the hood, but the optics are in perfect condition and the aperture works perfectly.

I need to sell this lens to get the funds to replace my compact camera (Fuji X10), which was stolen a few weeks ago.

Final price drop, £300, which includes RMSD (UK only), if no takers then it'll go on ebay.
