IT WORKS - Carestream Dental Xray Developer

[Rafael Ramos]

As i stated in a previous tread i had bad intentions to use Carestream Xray against b&w film.

i bought a camera and walked home testing it. nothing good, many mistakes, but instead of going with the trusted id-11 i took a leap of faith and went straight with the Carestream.

here are the results.
Carestream Dental 500ml, stock
ilford hp5, multiple ei (400, 800, 1600, random i dont know ) 5min, 23ºc, agitation 30sec+10s/min
scaned with a p7800+leitz eldia
as i expected it is FAST and very high contrast. at box it gives the thickness of carbon paper, but the info is there. i believe 5 minutes would be for 1600-3200.
i expected bigger, newspaperish grain, but hp5 handled well.

Nice pictures. Some of them look nicer than "properly" developed ones. If you want to determine a speed for that film/dev combo I suggest you shoot a few rolls of a still life scene at different shutter speeds. Then you can develop for 5 mins and see which exposure you like the most -- this one will determine which speed you should shoot the film at for that time. Try 4 mins and 6 mins also, it will tell you other things about the combo.

By the way, this looks not unlike what happened to me when I lost track of two rolls of Tri-X, one which I shot at 1600 and the other at 400. I developed both at 1600 and your pics look like the one I shot at 400 but developed at 1600.

tks, guys.
i was planing, indeed, a test with a macbeth chart, mid-gray and all whistles&bells. this roll was supposed to be a camera (nikon n/f65 i just got) test with id-11, hence the 'random' variation: i was trying the diferent modes, ev comp. but than thought: eh, what is life without a bit of emotion... and threw the 'syrup' stock into the tank

but i'll do it properly, perhaps tomorrow.

what i say about this developer: until we have a proper dev-time table be aware that is FAST in stock concentration and the contrast is very high. i would suggest at least 1+1 if a more tamed contrast and thinner negs are desired.

i didn't check thoroughly but i believe the overcast sky in most photos blew out flat and there is no 'base' shadow.
i am also getting the grip of the scanning contraption with the leitz eldia (the leica negative copier) so this might have induced some mistakes too.

On a USA dental supply site it is for about $11 for powder to make 9 litre.

Also there is another brand with single sachet packets ($1.02 each) to do a batch 1000 ml of fixer/hardener and 1000ml of developer.

Not bad at all for a first test. Do not hesitate to go to higher dilutions (1+10?? adjusting time, and one-shot) for a more pictorial rendering.

This may be the MSDS for your developer: https://cs-extwercs.carestreamhealt...tion=d__value~&CUSTOM1=Rapid Access Developer

 

[Rafael Ramos]

yep. exactly that.

i never sar a d-19 negative but from the description looks that it is very similar.

i think it will be a good first developer in bw reversal.

sorry, mate. only noticed it now.

indeed it has potential to achieve Moriyama-sama look. maybe if pushed up to 24 or 50k the hp5 achieve that almost b&w instead of grayscale apearence.

now i just have to get myself a pen-ee, some safety film and go shoot the underworld of rio de janeiro.

(if i dont comeback you guys know why)

Hey,
I've ordered some Carestream based off this and your previous thread! I am super nervous to give it a go, was wondering if anyone could answer a few questions I have so I don't totally destroy all my film!

X-ray developers are designed to have significantly higher contrast than normal film developers. You would need to use them quite a bit more dilute than for dental use.

Ilford ID-72 is an Xray developer for medium contrast this is the PQ version of ID-19 which is the same as Kodak D19.
