A developing question - what happened here?

[alienmeatsack]

Update on my situation... Hope the OP is ok with me using their thread for this, he says after he's already hijacked it. 😀

I did 2 rolls last night and made a point to be much more gentle with the agitation. I gently tilted the container over 90 degrees and gently turned it back up instead of just kind of going hog wild as before. I noticed that my Diafine B still bubbled up a bit but not nearly as much as the last time. I did not see any streaks or bubble artifacts on the film after the fact.

I also added Photoflo to the end to help with drying and waterspots. I think it helped some too. Well minus the fact that I dropped the wet negatives on the floor and had to re-Photoflo rinse them after rinsing off the dog and cat hair and dust.

I am going to do a roll of test shots this weekend when the sky is clearer so I can get a nice even toned area to test for the streaking/bubbles issue properly. But I am confident that the issue has mostly been worked out.

Again I appreciate the feedback here from everyone on this issue. And a special thanks to the OP who's thread I hopped into and utilized for my own issue. Thanks all!

Hi All,

Just started developing B&W at home a few months ago, and had a question for the gurus about my most recent roll. The negatives turned out starry and in some spots so washed out that the images are completely gone. I surmise this came about because I kept the film in its stop bath for too long (about two minutes, as opposed to thirty seconds), I read that this can cause acidic burns into the negatives. I just wanted to check here and see what y'all have to say about it.

Attached are some examples. Kind of a cool effect actually...

You have several issues going on there. First, you have developer surge as evident in the higher density marks from the sprocket holes in the film, the white blobs would not be caused by too long in the stop bath since they are pure white, and dirty drying. The surge is easy to get rid of by pre-soaking your negs for 2 minutes prior to putting in the developer. Also, you need to change your agitation a bit. Too aggressive gives you the surge, and not enough gives uneven development. Here are the proper steps for developing 35mm (and really all) film. Load onto reels, and presoak the film for 2 minutes @ 68 degrees and tap the can (I lean toward harder rather than softer taps) 5 times. Don't soak longer as any increased time in any liquid swells the film and you should try and avoid that. Next add the developer in a steady, but quick action. As soon as the dev. is in the tank, put on the top and tap the can 5 times and start your agitation. While you are inverting your cans, make sure you twist them as well about 180 revolution for each inversion. I agitate for the first 30 seconds then 3 taps before putting can down. Repeat every 30 seconds, agitating for 5 seconds, until you are done with your development time. With 35mm film I also, during one of my 5 second agitation cycles, instead of doing the inversion agitation, I set the can on its side and roll from side to side for the 5 seconds. If you mix enough of these into your agitation scheme, you will never get any surge marks.

For stop, only 30 seconds but even 2 minutes will not damage the film. It's not great for it, but it will not damage, unless you put too much acid in your water, and then it would not give you white marks as you have in your photos. Then finally into your fix for however long your fix suggests too. Agitate for the first minute then 30 seconds every minute thereafter.

Finally wash for 5 minutes, then 5 minutes in Perma wash or any other hypo clear solution, then final 5 min. wash. 30 sec in Photoflo and hang to dry. Do NOT squeegee or anything else...just hand.

Hope this helps.
