[QUOTE="WayneF, post: 155543, member: 12496"] Posting here (on any computer monitor), it could not matter less what the image dpi value is. 72 dpi or 7200 dpi, it simply has no effect on the monitor, it is totally don't care. dpi is for printing on paper. Image size (dimension in pixels) is all important. in video. The purpose of a light tent is to hide reflections in shiny things, usually glass. Reflections of the room, of the lights, even of you and the camera. We don't want to see that reflected in our shiny subjects. So the light tent presents an evenly lighted blank white panel everywhere, which is reflected, but which we don't notice. The tent is lighted fairly evenly to make this be true. For example, your second, the close up in the sun, is lighted from above (shadows underneath), and the top panel and sun is reflected, right above the eyes of your critter. If reflections in shiny things is not a problem, then the light tent has no native advantage (not necessarily a general lighting plan). It is diffused, but we can use larger lights (umbrellas for example) alone to create soft diffused lights, often more versatile and easier than the tent. But these umbrellas may reflect in shiny subjects, etc. Flash is very valuable in the studio, but flash has the downside that you "can't see it", that is, you have to evaluate the lighting in the test picture. But incandescent light, you can see and evaluate as you move it around to position it, but the exposure may have to be slow, like maybe one second sometimes. This works fine for inanimate subjects, and is good for light tents, but incandescent is fairly dim and does not work well for portraits of people, who move. For a start, see [URL="http://www.google.com/search?q=light+tent+lighting"]light tent lighting - Google Search[/URL] Note that if you have a visible frame inside the tent, it can reflect in the subject too. It is good to have the frame outside the tent, or to cover it with the same fabric. Anything not the same white cloth can reflect "differently" and be noticed. [/QUOTE]
