Use of X-ray film: technical discussion with example images

That's a nice photo. Sometimes developing defects add character to art.

Helps eliminate surge

I always use one size up

I've wondered about that. Thanks for the pointer. I've used drums for the 5x7 I've done so far, but thought about ordering trays for the x-ray to practice for eventual 14x17. I'll get 8x10 trays for the 5x7.

Should I opt for the smooth-bottomed ones? I've read that the grooves in most are scratch-prone.

I use smooth bottom trays with all x-ray film.

I worried about surge marks with the SP-810 and the UM-MA but so far my agitation method seems to have worked. Each agitation, I lift first from a different side of the tray moving in a counter- clockwise pattern. Also each agitation I make sure that I get one side agitation and one front or back agitation. Then again this is for 18x24cm film so it is a bit smaller anyway.

Good to know thanks. I have the 4x5 version of this. I emailed Tim and he said they haven't done extensive testing with 2 sided. I'll probably get this later on maybe next year.

I think this year, I need to save for an Intrepid so I can actually hike or something with my 8x10. You know...lockdown fun.

Agree

Hi Paul,

The driver is from the same seller. I used this one for use with a dimmer: https://www.ebay.com/itm/AC-Dimming-...72.m2749.l2649
If you don't want a dimmer a different driver is required (not sure why, but a dimmer will not work with a non-dimming driver). I just used a common low wattage in-line dimmer such as you might use with a table lamp. Works perfectly for me.

Great; thanks!

My 8x10 film arrived today, I've ordered the deep red LEDs, the driver, and will get a dimmer at a brick and mortar store.

I think I'm going to go to Goodwill and look for glass casserole dishes to use for the developing trays. We have a 7x10 one here at home that seems ideal. I'm kind of shocked at the cost of the trays sold for photography! Even used ones are unreasonably priced, in my opinion, for what they are.

Yah, I was thinking about casserole dishes as well. Good thinking. They are heavy though. And what if the wifey decides to make a tuna caserole one day and you need to process?

Plastic storage boxes are both cheaper and less heavy. I use them for practically all my paper and sheet film development when using trays.
