Q about 'macro' camera settings

[Edward Tinker]

red looks great for a bakcground, but as Don said, it leaves a 'residue' on the gun colors and / or makes the colors get darker.

So, although I prefer a robin egg blue background, probably a tan works well.

And the main thing with any pictures is plenty of natural light - subdued natural lighting.

Most of the time I take a quick picture, but I have found that many times the changing of the in the picture that the lighting or contrast seems to make the picture fuzzy, at least thats my experience...
