Fomapan&R09 strange results

[AndersB]

Hope this is the right place for post :rolleyes:

Hi everyone, I'm pretty new to this with developing my own negatives but i have done a few rolls so far and loving every minute of it

Usually i'm using D-76 but i been talked into switching to Calbe R09 and in same time also tried Fomapan 100 for the first time. I am getting a result i cant pinpoint what has gone wrong due to my lack of experience and hope someone else can help me.

Fomapan 100 developed 6minutes in Calbe R09 1+40 with 10sec of agg to start with then 3-4 turns every full minute rest of time.

Thanks in advance!
Regards AndersB

do your negs look thin?

If you mean the banding in the image area, that looks like a flow problem with your developer. I'm assuming you are shooting 35mm. I'd guess that your agitation method is too vigorous for the developer, and you're getting developer surge marks. The spacing of the surge marks appears to coincide with the sprocket holes on the film margins.

Sorry yes its 35mm film.

My first impressions where that the film did look thin.

The banding coinsides perfect with the sprocketholes and its there from both sides on most of the negs.

So i should use less agitation?

Consider a little bit different agitation "path" so that you are adding a little bit of a twist. Keeps the chems from flowing back and forth over the same path every time. A little roll of the wrist might help. Also, after the agitation cycle I rap the side with my free hand (heel of the palm) and set the tank down rather sharply. This should flick any bubbles off the film and up to the top of the fluid level (above the film).

Another method that is illustrated (but I've never tried it) in the Kodak Darkroom Handbook is a flat figure-eight. You have your tank sitting on a large surface, grip firmly palm down over the lid and swing the tank through a figure eight as it slides on the table top (sink bottom). One figure eight equals one inversion and at the end of every cycle, rotate the tank slightly so the angle of attack relative to the chemistry changes each time. Takes longer to explain than to do. But like I said, never tried this one. I either roll my wrist or am using a Jobo CCP.

I think i know what you mean and its sumthing thats easy to do. A flick of the wrist to get the chems flowing in a circular movement and not just up and down. The figure eight also sounds good. These result halted my trials so did not shoot anything today so i cant try it out directly but looks like i can start shooting again

Thanks guys for helping a noob

Apart from the banding, it looks underdeveloped - try a longer development time. I develop my Fomapan 100 in Foma R09 with somewhat similar agitation for 9mins (in 120 roll). And I like the results. (if you're interested, have a look at my website and check the BW photos part)

Also recently I've experimented with rating the film at EI 80 (and shorter time), it's even better...
