I do some product photography and always find trouble with black objects. If I don't have a good amount of lighting on the subject, it will be dark and I have to raise exposure and various other brightness settings. When I do this, it tends to draw out ugly features like splotchy color patches and graininess, etc. If I do put enough light on the subject so that I don't have to adjust exposure to brighten it, this does tend to make the black not-so-black any more. I can tell it's a little washed out, you know like more of a dark grey tone rather than really black. But then on the other hand, if I try to adjust brightness so that the object is actually black, of course that's no good because it's so dark I can't see the features of it! Normally I do alright with these photos but sometimes I get in a situation where I need to shoot black objects and dark grey objects together! I need there to be proper contrast different between them so I know one is black and one is grey, but I also don't want the features of the black object to get lost in the darkness. For some examples I've found some random Google images. This is a picture of a shoe that I would consider shot pretty good. I can visually see it is a pure black shoe, but it does get a bit dark at the top of the laces and strap. https://i.pinimg.com/originals/11/a6/14/11a614a260810315c61c54f2494974f6.png This shoe, I think, was shot less well, it does feel a bit too dark to me. https://media.journeys.com/images/products/1_375665_ZM.JPG Now here is a very overexposed photo. Look at the man's jacket. Clearly it's supposed to be a black jacket but it's washed out grey. http://lovetreephotography.ca/wp-content/uploads/2013/04/over-exposed.jpg This is what I tend to get on my products. A bit overexposed and washed out. But like I said, when I take down the lighting and change camera settings, it end up too dark. Or in other words, when it does actually look black, I've lost all the details. Fabric doesn't have a texture, I get blotchy color patches, weird things happen. And those problems only become worse in post processing if I try to bump up exposure and brightness later. So going too bright gets me a product that maintains textures, details, and for the most part eliminates color blotches and graininess, but no longer looks very black. Shooting to maintain original black tones kills small details, textures, and might introduce graininess and blotches. Increasing exposure on these dark photos tends to look very bad as well. I can't seem to find the right balance for black objects on a white background. Also, these are mostly matte finishes I shoot, I haven't had to photo shiny or glossy blacks yet.
