Does anyone here use a green screen backdrop to photograph your work? I know less than nothing about it, but it has sparked my interest. I did a google search, they are affordable, but that’s as far as I got. I should google more, I bet the software is the deal breaker. Any thoughts appreciated. Thanks!!

I have used a green or blue screen in video production. This allows you to remove or replace the background. For small product still pictures I use a Smith-Victor desktop shooting kit with four lights. For large item still photos I use a #12 Gray Savage seamless roll of 107” x 36’ paper. To support the paper roll I have permanently mounted a Manfrotto 046MCB Expan Drive Set to a wall. For locations requiring pictures on site of large items I use the Manfrotto Background Support System (9’ Width).

You can view all of these items a www.bhphoto.com

I have extensive experience with chromakey (AKA green screen) photography. The software isn’t the hard part. You can take care of that with any advanced editing package such as Photoshop, GIMP or others.

The killer is the lighting. You can’t just put something in front of the backdrop and shoot away. The screen has to be evenly lit, and reflections of it have to be minimized on the subject. I think that would be the hardest thing about using it for wood project photography. Even with a fully flat finish, you are still going to pick up the green on surfaces, and that will be a bear to deal with. Chromakey software will make it partially transparent, and even if you mask it, you still need to come back and eliminate the hue.

My recommendation if you want to paste your piece in a beach or meadow background, is to go with 18% gray seamless paper. You can buy a roll at a photo supply pretty cheap. As a background, you can remove it just as easily as chromakey green, and any reflections on your project will be neutral.

I have owned a Photographic Studio forever now….I tried green screen (chromakey) and the results were okay, but on people and shiny products I got some green reflections on like the chin-jaw line. I didn’t care for it at all…since then I have also tried blue and got a similar problem, so I just like the previous posters now use Gray. The software really doesn’t care what color you use, it will wipe out anything, but on people you have to be careful that they do not have that shade of gray in their clothing, unless you want to take the time to mask it.

I like it a lot, but you will have to use a grid or barn doors on your lights to stop any spill onto the background. There is commercially available colored plastic sheets. I now use only that to save on waste, and if you watch the sales you can get it very reasonable $100 for a long roll or $50.00 for a 8×10’ sheet. It is pricey to ship though…
