pretty sad how when anyone posts a great photo, others have to scream 'Photoshop' because that's the only way they could get a great photo.

I have seen many photoshop images displayed on Panoramio, but I am certain this is not one of them.

ION BEZERGHEANU / DIGITART if you look back through the comments you will find that the photographer explains the use of a fish eye lens

CAB1, if the photographer used a fisheye lens, THE WHOLE ISSUE must be round! That, any professional knows! So...?

Thank you Shan Khan, Bits-n-Pieces and CAB1!
ION BEZERGHEANU / DIGITART - there's no Photoshop trickery but I'm flattered that someone thinks I would be so skilled with Photoshop :o) The image is as taken, apart from level adjustment and cloning out a water droplet on the lens affecting the sky.
CAB1 is correct to point out it was taken with a 10.5mm fisheye lens which is why the horizon is curved and the whole rainbow fitted in the shot. The 10.5mm gives nearly a 180 degrees field of view, more than enough to take in a typical rainbow in its entirety.
I have a few other similar shots of the same event but they were spoiled by further water drops on the lens which is hard to avoid with a fisheye.
All the best, Graeme

Mr. Davidson, to see a photo made with fisheye lens, please clik on: http://www.panoramio.com/photo/26185519 The lens F = 10.5 it is not necesary fish eyes lens. NOTE: This photo is not made by me. I used to be clarifying what is fish eyes lens! Sincerely, and ...learn more! PS: in your photo..."the horizon is curved"...????? Sorry....

I do understand the difference between fisheye and rectilinear lenses with short focal lengths. The Nikon 10.5mm used in this shot is a fisheye lens as it does show extreme circular geometric distortion. However, since it is used on a DX (crop) sensor, it effectively takes a reduced crop out of the image circle.
Used on a full frame (35mm) camera and with the built in lens hood sawn off (!) it does give an image like the one you have kindly provided as an example. I have a photo of the sky taken with the same lens at http://www.panoramio.com/photo/12752091 which gives a better idea of how the image gets cropped on DX with this lens.
I do have a 12-24mm rectilinear lens for use on full frame D3/D3X cameras - I wish I had those instead of the 10.5mm/D200 used at the time of this photo. I would have preferred it if the sea horizon had been straight (linear) in this shot.
All the best, Graeme
