Blog #4 Finally the Lighting

Article #4 Finally the lighting

Blog #4 This is the 4th.th in a continuing discussion on how to get better product pictures. #1, #2, and #3 basically talked about how to set your camera. Also, there have been several books linked through amazon to help you get started on lighting. I normally use a medium gray background. A seamless roll paper background that hangs from the ceiling. I pull down enough to cover the work table leaving the product about a foot or 2 in front of the back part of the background. I actually have 2 of them mounted on the ceiling. One is 53 inches wide and the other one is 9 feet wide. I use the wide one only when I am shoot pictures of large items like camera cases or lighting kits. If you are shooting clothing like jeans, shirts etc. you can probably get by with the 53 inch background or smaller. You can actually cut them down to size to fit the room or area you are working in. The roll backgrounds just cut with a hand saw. 

If you are shooting full length outfits like suits or dresses, you really need a wider background like the 9 foot. Again, neutral gray, white, or black are usually the best colors to choose from. Unless you have access to PhotoShop and can really take advantage of the Chroma-Key green or blue. Of course it is difficult to shoot a white blouse on a white background. Just like it is hard to shoot a black outfit on a black background. Normally I do not shoot pictures of clothing so, I do not run into the problem of gray clothing on the gray background. Most of the products I shoot are photo related. Brackets, lighting kits, tents, etc. I usually use the 53 inch wide background because the products are fairly small. Say, 10 to 15 inches in size. Actually most of them could be shot on a small 15 or 20 inch piece of background paper. 

Why are we talking about backgrounds when this is supposed to be about lighting? Because you have to have something to put the product on before you set up your lights. I normally shoot my product pictures just like I would shoot a head and shoulders portrait picture. I use 2 lights with white umbrellas. Assuming that the camera is on a tripod and basically level with the product or just slightly higher than the item, one light, called the main light, is to the right of the camera and slightly above the camera. That throws the shadow behind and to the left of the item. The second light is level with the camera, slightly further back from the item and on the left side. The following pictures are from Smith Victor Lighting. They are very basic. All you should be looking at is where the shadows fall due to where the light and the background is.

I am unable to post sample pictures with the eBay Blog.  If you are interested in seeing this blog in it entirety with the accompanying pictures you can go to:

Notice that the shadow is very prominent to the left of the model's head. This because of only using one light and the model, or product is close to the background.

If we move the model, product further away from the background, the shadow becomes more diffused and is further to the left.

If we use a second light to fill in the subject and the subject is not close to the background, most of the shadows disappear. If you use umbrellas instead of direct lighting the shadows are even softer and less of a problem.

Basically you are creating the image 3-demensionally with the main light and filling in the shadows with the second light. The picture may look like there are not any shadows but, they are really there. If you just set each light up equally on each side 50-50 then the subject will look flat and dull.

This is a basic 2 light product or portrait set up. It should work well with clothing, people, small, medium or even large items. If you have set your camera to the right white balance, right exposure and used a tripod your pictures should look a lot better than before. Again, KIS, Keep It Simple. Only 2 lights produce only 2 shadows. They are much easier to work with than 3, 4 or more lights. That just confuses things.

Next I will talk about some special shooting problems like flatware or ceramic materials. Shiny objects like jewelry or coins.
