Thanks to everyone for entering! There's been a wide range of varied entries this time round, and I had quite a tough time deciding. I've got a little critique for everyone - I hope you find it useful, and don't take it too seriously.
My original image:
Most of you, as well as I, definitely went for the unusual outcomes this time. I'm glad to see that there as much scope for unusual interpretation as I had hoped.
3rd Place: Ash - Those vivid colours! That apple is definitely flavoured artificially, some kind of synthetic, sugary confection. I can taste it now... I also like how you've brought down the dark tones and cropped to make it look like the snail is slithering out of a hole.
2nd Place: casil403 - Almost the only monochrome image. Muted colours work well here, I think. The slightly busy background is not necessarily bad - What I really liked about this is the stony, relief-sculpture look it has, and the snail pops out nicely.
1st Place: ozlizard - Great grungy rendition! The shell has a lacquered, almost moist look, which I like very much. Of course it's unrealistic, but the image seems to match the slimy, dark-loving nature of snails in my mind's eye. Well done!
Everyone else: timh - Nice. I really like the handling of the orange tones, the halo artefacts around them not so much.
tackyat.2 - The slightly gone-off colours are getting somewhere, and I like the shell colour very much too. But you've really wiped out too much detail. Also, better to make a more detailed JPEG, this one is very blocky.
Voytech - The dusky pink is certainly different, but I think it could have done with a little extra variation.
jmschrei - Green is good! But The snail seems a bit too yellow and washed-out for my liking.
erkie - I like the almost mother-of-pearl effect on the shell. But the contrast of sharpening and blur is too great.
slowpez - The basic PP is nice, the extra snail is unrealistic! :3
VaughnA - I'm liking the contrasty tones, but I'm turned off by the extreme haloing. The bleached shell works well, but it looks like it needs to be done more selectively.
MikeS - You win the "Weirdest Interpretation" award this week...!
jheu02 - I actually really like the colours of the in-focus areas. It's as if there's a dusting of vivid powder paints. Would like to see a version without extra snails.
Parallax - Thumbs up to a conservative rendition - I like the creamier, relaxed tones here.
Finally, my re-working of the photo. I forgot to put one in the original thread, so I might as well show you here:
Again, many thanks to all of you for your effort and creativity.
ozlizard, it's over to you. I hope you've got something unusual lying in wait...
