C41 Processing

My one-time go-to lab for C41 (or any other processing at the time) used to be Peak Imaging. Since their sad demise I've not yet settled on an alternative. Doing a search brought up Gulabi in Glasgow. Anyone have any experience with them, please?
 
Ok. Thanks, Pete. I've had three rolls kicking about in the fridge literally for years (Agfa Vista 200, Konica VX 200 and Fuji Superia 200). With autumn's colours upon us I thought I might use some (if it's still any good).
 
Ever considered developing it with a kit? They are more ‘user friendly’ these days I believe.
I would, but disposal of the spent chemistry is the issue (one of the main reasons I use caffenol). We're on septic tank drainage, so I'm reluctant to put too many chemicals down the drain. I still haven't figured the best way to deal with the spent fixer. I really ought to get my finger out and enquire where I can take it to have it safely disposed of. I'm storing it in a plastic container for now. Not an ideal situation, I know, but my throughput is fairly small, so storage hasn't become a problem.. yet... 😬
 
I'm gearing up to do some C-41 here in the next couple of weeks. I've been keeping my spent chemicals in a bottle in the garage until I have enough to take someplace. Here's the kit that I've put together. The tall gizmo is a Sous Vide sold to cook vacuum bagged foods. It will heat, circulate and maintain temperature of the water bath.

That is nearly identical to my set-up I use at home Gary, lol. It works well. My sous vide machine is red though. I recently replaced my plastic tub with a slightly smaller stainless steel bowl thing I got from work (hospital) that I think was used to hold people parts (it was ran through sterile processing before being gifted to me.)
 
My sous vide machine is red though.
I probably bought last year's model. It was only $49. There were more expensive ones that possibly had programmable time/temperature. I'll be curious to see how it all goes. I get 120 degrees F out of the tap and plan to keep the water at 102 degrees F. I'll ensure my chemistry is holding at that temp prior to pouring it into the dev tank.
 
My Sous Vide is only calibrated for food.
I haven't read enough to know what sort of calibration might be required but prior to actually running it in my developer water bath, I'll double check the water bath temp as well as the temp in my tank. If I have to run it set hotter or cooler than my target temp, so be it. At most it will need to hold the water constant for 8 minutes. I'm curious about fluctuations and will likely run a bath or two to see how constant it is.

The good news is that I'm not planning to eat the film afterwards... :)

Also, I think I'm going to go with Film Lab for my scan conversions.

I was joking ... the Sous Vide instruments are calibrated to temps. I found my Joule to be very accurate. The Sous Vide has always processed perfectly developed meals.

You're just making my mouth water...
and no fair at 11:23pm.
You have a Sous Vide ... :cool: (PS- Because it was cooked, Low & Slow ... for a long long time ... it is super tender ... melts in your mouth. I filled the zip lock bag with herbs and peppers from the yard ... then I toss in a beer. Delish!)

Ralph,

I haven't shot film in a long while. But, for color I used 'Richard' with good success.

You did it! It looks perfectly cooked. Now you're ready for dinner.

Directions​

    1. Step 1Fill deep pot with water and set sous vide machine to 130°F for medium-rare. (Make sure to put pot on trivet or on stove, as it will get hot).
    2. Step 2In heat-safe gallon-size plastic bag, place steak, seasonings and 2 tablespoons oil and seal tightly, removing any air.
    3. Step 3Place sealed bag into heated water and cook 90 minutes (refrigerate if not cooking right away).
    4. Step 4Heat remaining tablespoon oil in large skillet on medium-high until oil just begins to smoke. Meanwhile, remove steak from bag and pat dry. Strain out seasonings from bag, discarding liquid. Season steak with 1/2 teaspoon each salt and pepper and cook until deep brown, 2 to 3 minutes.
    5. Step 5Flip steak and add reserved seasonings to skillet, scattering around steak. Cook until steak is deep brown on second side, 2 to 3 minutes. Remove steak and seasonings and let steak rest 5 minutes before slicing. Serve topped with seasonings.
CHOOSE YOUR SEASONINGS:

4 cloves garlic + 8 sprigs thyme

4 sprigs rosemary + zest of 1 lemon (in thin strips)

3 scallions (cut into 1 1/2-inch pieces) + 1 red chile (halved)

1 1/2 teaspoons coriander seeds (crushed) + zest of 1 orange (in thin strips)

Honestly, they look good. I waiting for some images.
 
The good news is the Nikon works and the lens focuses (after I had to re-attach the focus ring upon arrival). I need to get better with my metering. The CineStill C-41 processing went well. The copy/paste of one set of editing criteria in Film Lab is very cool however I'm not certain that my first go at processing my negative to positives is the be all/end all.


More experimentation is required.
