Jobo 2509-N: 6 sheets or only 4?

[Lachlan 717]

I'd like to get Users' opinion on whether it is better to only load 4 sheets, rather than the maximum 6, per development with the Jobo 2509-N drum.

I have seen mention of getting more consistent results with only 4; 2 on the inner most track and 2 on the outer most.

This question is specifically in relation to constant, machine agitation.

Thanks in advance,

When I used the 2509, I used just four, never tested it to see the difference, if any.

I've just used 4, even Jobo recommends 4 instead of 6 .

a friend told me about how some of his film stuck together when he processed 6 sheets together at a time, didn't turn out so well .

stick with 4 IMO

A bird in the cab is worth 2 in the bar?

Looks like 4 it will be.

Thanks, guys.

I've always used 6 with B&W. Never had any problems.

From what I've read the old wives tale about only using 4 sheets was based on the original 2509 reel, NOT the current redesigned 2509N reel with the extra side baffle pieces. Hence I've done 6 sheets of E6 in mine with no problems.

No problems here so far with 6 sheets of 9x12cm or 4x5 in the 2509n (black baffles attached) with rotary processing (B&W only).

Also for me no problem with 6 sheets in the 2509N reel with with the black baffles, when I used the 2509 I used only 4 sheets

But (hope you do not mind hijacking the thread a bit) I do have another problem at the edge of the negatives,: extra density and no density at the place were the negative touches the little small protruding clear rod.

Another member of this forum (with whom I communicated) has this problem too, Drew Saunders his image here:

shows the problem I have, hope he does not mind ;-)..

It's seen on the right and left, about 5% from the top.

I do not have it always, and no clear relation with film, developer or speed used, maybe there is with the position, don't know

Any insight and perhaps solution appreciated!

Best,

Cor

Cor, I had similar marks with the 2509N too - but I thought I bend the negative (in the film-holder loading/unloading-process) to much and a „crack“ or something in the base caused the problem. This happened only once (the only time I've tried stand-development with the Jobo 2521) and the (rotary-) development seems to be even since then.
Please excuse my crude english, georg.

Thanks for the feedback, George. Not sure If it is caused by bending, the marks are at the exact place were this little white rod is. That said, I load directly onto the reel, I do not have the loading device

best,

Cor
