I have been thinking and am keen to try some indoor macro photography now that it is the winter season. I have not got much cash so was going to improvise a bit with set up. If I had say 3 desk lamps and say created a white box would this be effective in creating a mini lab?
It works for static subjects shot with a tripod, you can make the exposure as long as required. One trouble you may run into is "mixed lighting" That's where the color temperture of the lights may not match. You can't fix this in post processing, well not without spending hours at it. So just make sure to use lamps all of the same kind. Or just one lamp and a reflector
It is easy to color correct if you first shot a grey card then without changing the light replace the gray card with the real subject, Or shoot the subject first grey card second. Then in post processing correct the grey card to neutral grey them apply that same correction to the subject. Using "real photo lights would save you much of this hassle. Shot RAW so that you have more options in post.
It is actually easier to shot this way than with a flash because you can see the effect of the light and how the shadows fall before you snap the shot. My strobes have modeling lamps built in. I don't know how you'd set up a shot without them.
Use the self timer to trip the shutter, any vibration will blur the shot
