Thanks for your thread, it motivated me to submit and see if I pass the test, which I did with my first 4 images.
I used some recently uploaded photos from
http://forums.overclockers.co.uk/showthread.php?t=18182025&highlight=pika
The pika and squirrel in photos 4 and 6.
To this I added a photo of a wild chamois/mountain goat. (which was razor sharp).
I added variety with a landscape shot of lake Louise, nothing special, typical tourist photo 2 minutes from the car park but I had good lighting at 7am.
It is a pity most of my stock portfolio which has all been well processed and key-worded with IPTC are taken on my old 6Mp so aren't natively of high enough resolution. My best quality and best selling few dozen I might interpolate once I have read ALamy's instructions.
But now it is the tricky stage, waiting for sales. It will be interesting to follow as most of my previous stock work did not involve nature photography and if I get even a few sales of nature shots on Alamy then I will be happy.
I hope you get accepted soon. Although I have no idea what the reviewers are looking for, I think having fairly standard photos of high technical quality helps. What I mean is that they may not be looking for highly processed images, at least for the initial test.Stock photography is not the same as art sales, and this is important for technical reasons as well as aesthetic. Things like sharpening should be done at the last stage of production, therefore submitted photos should not already be sharpened, leave that to the graphic designers.
