I am planning to get on alamy and I failed QC at the 1st try as 2 of my 4 images failed.Now I have 3 images ready to be submitted to QC but am perplexed about the 4th one.Could you help me figure out which 1 of these should I go ahead with, if any?Alamy don't look for subject matter but that the images should be technically sound.

Both are clicked with aperture f/10, iso 100.Ofcourse I would be correcting the exposure in photoshop, but I would like you to tell me if any of the 2 or both are fine and technically sound.

Then I have these 2:

http://dl.dropbox.com/u/42878955/4.jpg

They were clicked at a memorial.Both are clicked with aperture f/8, iso 200.I know there are exposure problems with all, but I will be correcting them in Photoshop.The thing I need to know is which image is technically sound and safe to be uploaded for the QC, as I don't want to take any risk.Thank you.

What were your 2 images failed on?

Yes, but the others weren't relevant to you.

The images with the statue are shaken. Use a tripod.

Okay.There wasn't enough space for tripod as there were alot of devotees.Was scared to bump up the iso as that may have increased noise.Anyways, what about the other 2?

the DOF is quite thin even at f/8, because you tried a kind of closeup with the 18-55 kit lens. Image is lacking definition on the petals.
Regarding high iso, you have to ask yourself: would I rather get lucky and not shake the camera at iso 200 (less probably) or I'll try and reduce noise from a shot at iso 800?
D5100 is pretty good with the noise, try it.
And you don't need f/11 or f/8 at the statue shot.

You can use a tripod as a mono-pod (keep the legs together) - or use a mono-pod. It's footprint is less than yours so it is possible to use in a crowd.

These look soft. Especially image number 2 looks shaky (it's 1/5 seconds hand held!)

Use
1) Tripod +mirror lock-up
2) Good lens (These are shot with kit zoom lens)

If you want to pass QC, do not post any of these images, shoot new sharp ones.

The kit lens should be good enough to pass the QC as long as you work within its limitations - use around f8, bright light, don't shoot into the light (lens flare), avoid the extremes of the zoom (or at least pixel peep or check online what the sweet spots for that lens are), avoid high contrast edges near the perimeter of the pic (chromatic aberration) and so on.

Use a tripod and low ISO. Don't send them anything that you can see anything wrong with (bits out of focus, motion blur, camera shake, poor exposure). Getting the proper exposure will do more to lower digital noise than keeping iso at 100 vs 200.

The goal here is to get enough technically perfect images to pass the original QC test, if the conditions aren't good enough to get a perfect image, then don't send it in as one of the QC test images.

kit lens (18-55?) is fine
some people shoot with prosumer cameras and pass qc
the image links are broken so no idea why they failed
but the response sounds like some obvious blurriness on the image

I know it's obvious but remember Alamy doesn't judge content just image quality. Shoot in good light, sharp images and get in, then work on the rest.

I originally passed with a 10D and a 28-135 lens. Nice versatile lens, but no "L" That was back when they required upsizing! I always shoot at 100 ISO unless it's just impossible. Also I use a monopod much of the time.

Send in the sharpest, clearest, best exposed, clean, colorful images you have.

Two things it appears people get failed for on Alamy QC are SoLD and artifacts = spots, dust bunnies in the sky. (birds will do it, even if they are honestly birds)

It's not hard to get accepted at Alamy.
