Dev times Daylight tank vs G3

Post by popcassady »

I want to do some clip tests later on this evening. I'll be developing them in my stills tank.

How do the developing times compare to those of a rewind tank?

Also, what about agitation?

What stock are you using?

As for the agitation, just running the rewind tank is enough-you won't need to pick it up and shake it about and such. Actually, agitation in that tank is a little too efficient, as the chemicals can quickly oxidize in it.

Sorry... I meant for the daylight tank. How do I mimic the development times and agitation of that of the rewind tank? Is there a rule of thumb, or is it just a case of test, test, test?

Here are daylight (LOMO) tank instructions I use with my own modifcation to them creating optimal results for my style of processing.
(Original instructions credit to Martin Baumgarten)

LOMO tank E-6 processing instructions.

Start timer once ½ of chemistry is in tank. Start draining when :15 seconds remain in step. Fill tank as quickly as possible.
Step Time Temp. (f) Comments

First Developer: 6:00-7:00 100.4 +/- 0.5Initial and Subsequent Agitation
Initial Agitation: Tap tank to dislodge bubbles. Return tank to water bath. Rotate reel 4-5 times during first 5-10 seconds.
Subsequent: Rotate reel at 30 second intervals 4-5 times._________________________

Wash 2:00 95-104 Flowing wash

Reversal Bath 2:00 95-104 Initial Agitation

Color Developer 6:00 100.4 +/- 2.0 Initial and Subsequent Agitation
Initial Agitation: Tap tank to dislodge bubbles. Return tank to water bath. Rotate reel 4-5 times during first 5-10 seconds.
Subsequent: Rotate reel at 30 second intervals 4-5 times._________________________

Remaining steps can be done in room light. But it is recommended to leave tank closed to contain heat and promote continued even development.

Pre-Bleach 2:00 95-104 Initial Agitation

Bleach 6:00 95-104 Initial and Subsequent Agitation
Initial Agitation: Tap tank to dislodge bubbles. Return tank to water bath. Rotate reel 4-5 times during first 5-10 seconds.
Subsequent: Rotate reel at 30 second intervals 4-5 times._________________________

Fixer 4:00 95-104 Initial and Subsequent Agitation
Initial Agitation: Tap tank to dislodge bubbles. Return tank to water bath. Rotate reel 4-5 times during first 5-10 seconds.
Subsequent: Rotate reel at 30 second intervals 4-5 times._________________________

Wash 6:00 95-104 Flowing wash

Final Rinse 1:00 Ambient Initial Agitation

Dry As needed up to 140 Hang or on reel
If drying on reel Imerse in Photo Phlo for 30 sec to promote even drying.
Drying on reel results in cleaner film.

If you're procesing B&W you can pretty much follow the same instructions as for processing still B&W reversal. The E-6 instructions here are exactly the same for still film as for MP film. These instructions will also work fine for bucket or puhskettii processsing 50' in a 4 reel 35mm tank.

Enjoy processing your films. There's something to be said for having complete controll from cart in the camera to process, to projection/ or telcine.
