    Like I said before, x-ray film was made for alt processes!

    I mentioned developing in Rodinal 1:200 for 6 minutes which I tried with dental X-ray film exposed in a 35mm camera.With the film developed in a tank I was agitating for the first 45 sec & then 15 sec per minute. The film was in 600ml of developer. However there was just traces of a negative. Maybe the film would have developed properly if I had given a time of 10 min, or if I had agitated continuously for the whole 6 min. Both need to be tried

    A 1:100 dilution works fine with the agitation I mentioned. It certainly seems that D band dental film is around 100 ASA

    The film may be 100ASA, but is seems rather grainy. Is that likely to be because it is double-sided coating?
    The image is taken from x 30x40mm dental X-ray film used for research purpose in getting a closer approximation of the dev time before I use large-format X-ray films.

    I think so. I have switched to HR-U, no problem. The last I looked there was still some HR-T available on Ebay, but I thought I'd rather buy newer film than familiar film, since I'll have to make the switch sooner or later. The curves aren't very different.
    Thanks, but I'd rather just watch:

    That figures, I'm always the last to know. I've only ever bought one box of x-ray, and its still 3/4 full. I finally got my first acceptable image and by the time its gone I'll finally know what I'm doing and I won't be able to get anymore. I'[m tempted to just throw it in the freezer and move on to HR-U right now.

    Use up the HR-T---you won't see a difference, I don't think.

    In Europe, we can get Super HR-E 30 and Super RX: are they OK?

    I went to the windmill at Skidby yesterday.
    I was going to take a walk along a footpath into the village & back, but I saw this huge bank of lead grey clouds coming.
    The last thing I wanted was for my Graflex to get rain on it, so I went home.
    I had time to make the images below. In the hedgerow shot you can see the heavy grey clouds.
    This is the first of the Crontex MRF-21 I used. It is single-sided and has some kind of back coating. The proper developement time for this seems to be 8-9 minutes in Rodinal dil 1:100.
