I have strange line's on my photos - doing something wrong in the development B&W

[Andrew O'Neill]

I've never used the yankee tank, but I suspect that it would work better. Have you ever considered using tubes, like the BTZS, or homemade?

I've never used the yankee tank, but I suspect that it would work better.

The Yankee tank holds the film from the bottom and top, instead of from the sides. What happens is that when it is agitated using the little handle-stick, the holes in the bottom create a surge of developer. This forms a surge pattern on the film.

The instructions on the tank lid indicate that it should be rocked back and forth, but I've only done that intermittently. This gave uneven development. I suspect that that the user is supposed to rock the tank back and forth continuously, but I've never tried that. I suspect that the density would still be uneven, with the top of the sheet receiving more agitation than the bottom.

If Yef does have a darkroom, or at least (like me) a bathroom that can be made light-tight, then he could use a slosher in a tray.

Why not use a Jobo tank???

Why not use a Jobo tank???

Well I guess that's what I'm gonna do ( buy a jobo tank ) but the thing is that my Petarson with the Mod holder was working find till now :-(
I'm developing with continues rotation ( all the time - non stop ) .

I'm happy that it's the developer and not something else :-)

Thank u all
