I am being turned down by stock companies for these two things . How do I get rid of these and how did I get them to begin with. (chromatic aberation and fringing)
Is it a goofy idea to try to sell to stock companies ?

Some examples would help. I can find no pictures posted by you anywhere on this forum to see what the problem may be. No one is going to buy photos with CA or fringing in them.

Using a smaller aperture can help. CA control is available in JPG on many new cameras, and in Camera RAW in Photoshop.
You see the Red/Green or Blue/Yellow halo around areas of high contrast.
Wide Angles can exacerbate it, branches against sky are horrible for it, ED or L glass and Aspherical elements can help prevent it.

Usually it happens with the cheaper lenses. I use lightroom and it usually always gets rid of it. You just have to learn the conrtols

To MT:

How many feet away can you be from your subject, and still get a finely detailed resolution, using a 200 or 300 mm lens? Currently using a 55-200 kit lens. Can't afford any thing better right now.

When I take photos of animals or landscapes, I have to crop away almost 30% of the foto. Then when it is printed the resolution is lost.

If I knew how far away I should be, I'd either shoot, pass up the shot, or wait till I got a better lens.

Stock companies use this excuse because they dont want to tell people that there images are not that good. Its an excuse.

Here are some of the items you asked for. I am using a Nikon D5000. Lenses are kit lenses AF Nikkor 18 - 50 mm 1:35 - 5.6G and Nikon DX Nikkor 55 - 200mm 1:4 - 5.6G ED
I don't know if this will help in yor analysis but would sure like to find out.

Thanks a lot ,j.

Do you mean 18-55? Are both the 18-55 and 55 200 VR? I have a D90 (very similar to D5000) and those lenses, I get very different results. Look at the area around the little girls chin/cheek. Very soft, full of fringing color. The bench picture also is very soft, very low contrast.
Unless you have bad samples of lens, I think your problems are in the post processing. Your exposure settings seem reasonable. Good examples of your equipment are more than adequate in performance.
The low contrast of the bench picture reminds me of a poor quality HDR, or one that requires additional work to add contrast.
Can you tell us what software you use, what is a typical workflow, or what your camera settings are? You might try a hard reset on the camera and start from there. Do some controlled tests with your lenses.
Good luck, hoping there is a simple solution,
Dave
