Could you hold the paper vertically? Next how would you accurately time your exposures? The projector lamp my not be designed to be turned on and off repeatedly, it may shorten its life.


Lens cap?

Fabric stores here in USA have upholstery velvet and dress velvet. The dress material is blacker but does have a little bit of a sheen. I have two 3 yard long pieces sewn together to give me a full "seamless" sized backdrop. I block as much light as possible from hitting it.

For macro work in confined spaces where lots of light will hit the background, I use a piece of black flocking material made for lining telescope tubes. Super black but too expensive for large sizes.

To convert negative to positive, open file in Photoshop, then Image>Adjustments>Invert
From there you adjust whites, blacks, and contrast, etc as required.

OK, so the software does the conversion to a positive jpg image.
I must be missing something because if I scan a negative it comes out as a negative.
Thank you for clearing that up for me.

In the scanner software, you must select "negative".
It sounds like it's set for slides.

Amazing details and colors!
For a really BLACK background, use black dress velvet and place it as far from the subject and lights as possible. The distance is the key.

I see it has 100% sRGB color gamut, fine for web but if printing your own stuff, might be worth spending more for a wide gamut monitor.

Sounds interesting. Could you do a comparison shoot under stable conditions and show the similarity / difference?

Use Anti Static negative cleaner. It's not expensive and it works great.

Just flush the neg with it to get loose stuff off and then wipe with pec pads and the cleaner.

The problem is that any method that involves wiping across the film, is liable to drag dislodged abrasives across the film, adding scratches.

I think Scotch Tape (no residue type) might work too.
