Densitometer for X-Ray , can it be used ?

[lhalcong]

Can an X-Ray film densitometer be used also to measure density for Photographic Film ? even though it was not specifically design for photography. My educated guess says NO , but I dont know how different is X-Ray film from photo film in terms of measuring density. my Purpose: I am looking for a cheap densitometer that will allow me to learn, test and play with the Zone System .

thanks in advance,

Can't see why not. Isn't a transmission densitometer measures much light is transmitted through a medium on a logarithmic scale?

Should work fine - unless it is one of those fancy ones that reads a whole sensitometer test strip at once.

Yes. I have two densitometers. A Macbeth and RH design. Both work fine on xray. I use the Macbeth because it has colour channels so that I can accurately read xray negs that have been developed in pyrocat.

Perhaps you are asking about X-ray film Sensitometers (that have green or blue LEDs in them)?
The answer is yes, ok to use with panchromatic film for most control-strip tasks. (there was a url link here which no longer exists)

Never mind, that one I was looking at on eBay is gone. Sorry to ask for a different one. I have no budget whatsoever for this but I'd like to be able to play with the zone system per A. Adams
will this one work. ? seems very cheap , hope nobody snatches if it really is good.

If you post the Ebay listing on APUG, you might have it snatched out from under you
