Hello everyone.
I will apply  my first three imagas in the next 2 days  for photographer in istock photo. Please help me to chose  3 for application samples. I hope   that  5,4,9  are ok ?



it is my 6 Attempt (  I have photos rejected with the same status:
"Two or more of these images are very similar in subject matter, perspective or style. We would like to see a demonstrated range of diversity in technical ability and a variety in subject matter. So if you have anything else you can show us we would love to see it. We welcome you to return after the number of days specified and upload fresh samples of your work and we will re-process your application. Please note that you will not be able to upload new samples until this waiting period has passed."

Thank you in advance

Comments are based on my personal experience:
bal_atom_var: although nice materials and render, there is nothing to do with an atom or anything stock-related, from the point of view of a designer. It's only a nice, wallpaper-like image. (= where do you see your image used?? If there's one or two, it's not enough)
cam8: too much useless detail, cropping and banding in background, anti-aliasing of lines is very low quality
case_2: can't see
eagle on red: good stock photo! Be careful, there's too much banding on eagle and background!
high_cam8: useful, but as in case of cam8.jpg, too much useless detail, anti-aliasing problems.
kapitel_n: very beautiful details, but please make a composition more suitable for stock. (examples: designers can (virtually) support something with, or can hold something on the columns)
rect_2: good abstract, although iStock may not accept, others may found usable
Speed_4: It may be good, but I can't see the usefulness
tel_7: the most useful rendering. Pay attention again to the banding on the image!
water_cam1: that aren't water molecules, maybe something organic, but then you may want to use different colors for carbon, oxygen and hydrogen molecules, and make something realistic (=relevant organic molecule of sugar or something)

Note on banding: save 16-bit lossless format from the 3d app, so photoshopping will not introduce banding. Keep this format in 16-bit and don't touch, by making corrections with adjustment layers. Save as jpg for uploading.

I had some banding issues no matter what quality settings used and massive render times for no apparent benefit - thanks for this info.

You have a nice portfolio!
Regarding the banding, it does matter the bit depth. If the banding is introduced by the texture, try to use 16-bit textures. The important thing is to save the final rendering as a 16-bit file (preferably a tiff or png). With all these, after photoshopping, it's still possible to have banding, in this case you may try to add some noise as follows: 1. create an 50% gray layer in PS; 2. Filter -> Noise -> Add Noise, amount of 1...2, don't tick monochromatic; 3. Set the layer blend mode to Overlay; 4. If the noise is too much, reduce the layer opacity;
Finally convert the 16-bit file to 8-bit (to save jpg) by first flattening the image and then convert to 8-bit!

Are you sure you can even apply for a photographer's account with 3d renders ?

AFAIK 3D images are considered photographs at IS. Sean?

They are - I do both 3d and photo at IS but I thought that the application itself was restricted to photos only

yes renders = photographs

... BTW it's nice to see 3d, illustration, etc. categories at different agencies but what about 3d renderings combined with real photographs? Which category to pick?

New one: Composite

Thanks to all ,  i am in 

Congratulations! Did you get in with the render you showed here?

I have fixed banding on red telephone and eagle and  have added one another picture
