I'm sure the pic is 100% genuine and just taken with a not so good camera and probably in a hurry. I don't know the PH (Arnaud Mermet) concerned personally, but I do know his reputation and it's one of the very best. Some of you my remember he posted here a year or two ago - and some of you may also remember his website, which has plenty of stunning trophies. - Believe me, he has no need to mess with images to make them look bigger. The same could be said of the company he works for. They're one of the best and most ethical operations in Africa. - Frankly there's no doubt in my mind as to the authenticity of that image.

Don't know if it'll help, but I took the original image into photoshop, cropped it, sharpened it once, and then used the auto balance tool to improve the colour balance.

I can't do anything to improve the definition of the tusks because of the mud on 'em.

FWIW, to explin the colours in the original image, the foreground looks like it was burned, probably earlier this season, hence the short grass/new green growth. The area immediatly behind the Elephant was probably burned the year before, or maybe the year before that, hence the coarser taller grasses and further back, looks to me like it could well be riverine habitat and if you look to the right hand side towards the top of the image and look through the bush, it looks to me like you can just see bits of the opposite river bank or if not, it might be a fallen tree trunk........ I might be wrong on that though.
