Re: galaxy-paper direct positive
Sorry to be so full of questions but....
How dim will a safe light have to be to handle this material?
Does it's sensitivity to light have a cutoff at a certain wavelength?
I see on your home page photos a S-11 style safelight bulb, if this is the correct bulb will you have it available or a link to a supplier it can be purchased from?
Waiting in anticipation.
Re: galaxy-paper direct positive
So, I also wonder if the 5x7 will fit directly into 5x7 holders. If so, I would be interested in trying it out. I guess the yellow safe lights are not safe for this paper, right?

I'm going to use my "white LED battery powered light, taped up to shine through a brown beer bottle" safe light. I've found it safe for about 5 min. with most paper, even very sensitive Oriental Seagull grade 2 RC paper. That's aimed up to reflect off a white wall.

Be sure to post a picture of your safe light!
So, the Thomas safe lights are not safe with this paper? I think I have an old Kodak red safelight but can't see much with it.
Re: galaxy-paper direct positive
What does the spectral response look like? I understand the use of a dim red safelight means it is not red sensitive but is it blue only, blue/green or a kind of ortho that only falls off at the red end?
Re: galaxy-paper direct positive
Thanks, that's good to know.
Re: galaxy-paper direct positive
Sorry, does this mean the paper will be safe under the Thomas safe lights?
Also, does a sheet of 5x7 fit into a standard 5x7 film holder?

What is the paper thickness? Is it double weight or single weight? If it exceeds the thickness of sheet films it may not slide easily into a standard film holder. I recently queried Ilford for the dimensions and tolerances of their 5x7" film for one of my projects; here are the results (inches):
Thickness = .007
Length = 6.95 +/- .031
Width = 4.92 +/- .031
I did not inquire about the 13x18cm size (close to 5x7), as I don't use that metric format, but I do know that it is a bit larger than 5x7 in both length and width (as much as .125" wider), so it would need a different film holder than 5x7.
I assume Kodak films are very similar to Ilford's regarding dimensions.
Re: galaxy-paper direct positive
Pledged for some 8x10 paper.
I have never used (nor been interested in) direct positive paper, but I figured it's worth a try, and the price is right. Might be interesting for some art shows/festivals I have booked for shooting instant portraits.
You certainly piqued my interest with the speed of the paper.

FYI. I noted this comment in post #7 by the product's source (emphasis is mine). The thread title is thus misleading. Just thought it might matter to some folks.
