I have found Ilfosol 3 to be a very good developer and can highly recommend it.

I used only Ilfosol S, many years ago now.

I found it to be a great and easy to use developer, but the shelf life of the concentrate at the time, was quite limited. I don't know about the newly named Ilfosol 3, but I would squirt an amount, of one of the various tinned gases that are available, to extend developer's life spans and that means with Ilfosol 3 or any other developer that you may use.

Kodak Alaris specifically recommends as their go to all around developer.

https://imaging.kodakalaris.com/sites/prod/files/files/resources/AJ-3.pdf.
Having just skim read the links PDF, I was quite taken back to read the following instruction, twice, on the start of page 2:

Before you turn off the lights, pour the developer
solution into the tank. Then turn off both the room lights
and the safelight

Smoothly lower the loaded film reel into the developer solution in the tank,
and attach the top to the tank. Turn on the lights.

I've never heard of this instruction at any time I've been using film = about 45 years.

Does anyone develop films in this fashion?

If I remember correctly, that was the method recommended for Techpan film in Technidol.

I have always followed the same procedure as outlined in the Ilford processing your first black & white film booklet.

https://www.ilfordphoto.com/wp/wp-c...rocessing-your-first-black-and-white-film.pdf



I personally don't like the procedure described above. I don't like the idea of liquids in an open container in the dark. It is an accident waiting to happen.

In a way yes. It is not that odd at all -- and it is the recommended procedure when developing, for wxample, four 120 reels(or 8 35mm reels) in one SS tank. These tall tanks even came with a rod you threaded through the center of all the reels so you could hold the end of the rod and lower all the reels into the developer at once. The fill time is so long on these tall tanks that pouring developer through the lid gives uneven development.

But I have developed 4x5 film on hangers that one dunks into open containers of liquid. Open containers (and trays) in completely dark rooms is photography.

Makes sense ... never thought of that.

Any reason for this weird procedure?
If you're referring to Technidol, I found this:

KODAK TECHNIDOL Liquid Developer Small-Tank Processing (rolls)
You can process roll film in small 8- or 16-ounce stainless-steel or 10- or 20-ounce plastic tanks with spiral reels using the following instructions. With some spiral reels, the 35 mm film may be susceptible to nonuniform processing effects if agitation is not carefully controlled. Pouring the developer on dry film through the light trap in the tank top can also produce nonuniformity. To avoid processing problems, pour the developer into the tank before you insert the loaded reel, and follow the agitation recommendations below.

Take a look at the Kodak datasheets.
A cursory review of the datasheets for Plus-X, Tri-X, T-Max 400 and X-Tol all recommend this.
It is probably relevant that the graphic used to illustrate this looks like a tank for steel reels - the ones that can be slow to fill and empty.
I have used that method in the past, but only with larger tanks.
It would probably be okay if you had extra tanks, and could store the loaded reels in one tank while you fill and prepare the tank used for development ahead of time.

I normally use SS tanks that hold just two 120 reels. If I was worried, I have seen the rods for that size tank, also. But my SS lids are fast filling, and I wet the film first, so I have no had a problem.

Okay, cool, thank you. What does "speed" mean in this context - shorter development times?

Do some tanks fill faster than others? I'm using an Arista quart tank, and it takes almost 30 seconds to fill (if I don't want to be pouring chemistry all over the place). I just read a suggestion that you tilt the tank sideways to fill, but haven't tried that yet.

Oops - sorry for the jargon.
"Speed" in this context relates to the sensitivity of the film.
If you use Rodinal or Kodak Microdol-X/Ilford Perceptol or (to a lesser extent) Kodak HC-110 you need to give the film more exposure, which means metering using a lower EI setting on the meter.
It most likely comes from the fact that if the "speed" of the film + developer combination is reduced, you will need to increase exposure by reducing the shutter speed you use.
Practice with some water - tilting may help.
The 30 second fill time is one of the reasons I prefer slightly longer developing times - they reduce the effect of any such delay.

Definitely tilt!

I use tanks that hold 1 liter, which I can pour in in about 10 seconds.

PS...my lids and caps for the SS tanks are also SS. A nice design that lets air in/out while you pour into it or out of it. The ten seconds for a liter is about as fast I would like to comfortably pour into that size opening without spilling. I can fill it with water a little faster (for a water stop bath, for example) over the sink.

Whenever I tilt a tank, I just put both the tank and the cap or lid on a flat surface and put one edge of the bottom up on the cap or lid.
Otherwise it requires two hands.

Oh wow, I didn't know the developer you use had any bearing on what speed you rate your film. I just read some development sheets for a few different films and saw suggestions to rate higher or lower than box speed based on which developer you use. Had no clue.

I've been practicing the tilt, and noticed it does help me get my pour times down a little, though it's a bit messier. Not sure if some tank lids are faster than others. I'm getting what looks like some uneven development, not sure if I'm taking too long to pour and developer is falling on the top rolls but not immersing until the pour is finished or if it's another issue.

I've been practicing and the tilt did help, though I'm still not as fast as I'd like to be. Gonna keep practicing!
