Is this the film they list as "Green"? I can't find B/RA 4153 listed as such on their web site.

Thanks,

Jim,

I think this is the stuff, although the photo they show with the listing is incorrect. This is the "blue" variety with a blue-tinted base. I just ordered a couple of 100 sheet boxes:

Beautiful exposure. Ektascan is hard to beat. Notice that there is no flare around the high lights. This is because Ektascan has an anti flare backing. So far as I know, Ektascan is the only X-ray film to be so coated.

They don't call it green in the sense other X-ray films are. It is even more orthochromatic than the green film. As a hypothisis, I would rate blue film the least orthochromatic, the green more so, and Ektascan the most orthochromatic of the films being currently manufactured.

Ektascan is also made in 14x17, which I cut down to 11x14. The scrap is used for smaller formats.

I think only 8x10 is common.

I also plan to stock up as I beleive X-Ray film will not be available as long as regular film. Medical users are all switching to digital. Very quickly.

Thanks everyone. I found the listing. The cost is amazing at only $4 per 100 sheets more than the cheapest 8x10 lith film. My order goes in today.
