How do you develop in a tupperware container, actually have never tray developed so do you leave the negative in the tray, doesn't it settle at the bottom, how do you grab it again. Do you close the lid, do you agitate the tray or move the negative? So many questions and most probably will irritate most members...sorry SergeiR for this basic stuff.Quote:

I wonder also. My finger are not nimble. I have to use trays with grooves to have any chance of picking of the neg. Some recommend glass plates in the bottom. I am thinking the glass plate would have to be undersized, to allow one the find an edge.
I am lucky to pick up pencils from the floor, let alone wet negs in the dark!
We will both figure this us out, you are not alone!

Xray is so easy to scratch that this procedure is not very good. Development is even, but the darn scratches. I get less scratches if I do only 1-2 sheets at a time though. Some suggest using flat bottom trays to minimize scratching. I have not tried that yet.
How do you pick up the negative in a tupperware container? By the corner. Push the film against the opposite edge first. It's easier to pick up. Also by agitating, a corner will come up allowing you to get your finger underneath. X-ray film is too fragile to develop multiple sheets together. One at a time.
You can use regular, grooved trays if you use my ziplock bag method.
Not recommended to use they often have a mold mark on the bottom that will scratch your neg.Quote:

At any rate, I do not use them anymore since I got hold of some flat-bottomed trays of several different sizes from a retired photographer. I don't recommend grooved bottoms, especially if you are using x-ray film that has emulsion on both sides. The bottom "agitates" differently than the top side and can result in developer marks. It happened to me. If you only have this type of tray, instead of a glass sheet insert, try plexi glass with the edges and corners sanded. Or you could try out the ziplock bag method. Much cheaper and works great!
found this zip lock method
