Edwal TG7

Jon Buffington · Jan 27, 2018

So not a lot on the recent interwebs about TG7. I went by the local "camera store" (use that term loosely, sells a little film but everything else is new old stock and used cameras as this store been around since 1893). They have a big shelf behind the clutter with all sorts of chems. Probably been on the the shelf since the 90's and early oughts. Cleaned them out of hc110, all good stuff. Bought most of their diafine and acufine which was fine. The old Edwal fg7 bottle I bought was no good. However, there is a nice big bottle of Edwal TG7 on the shelf. It looks syrupy like hc110 so I am hoping the chems are still good. I get all this stuff at discounted prices obviously. My question is, do you think the concentrate is still good? Secondly, and more importantly, what is your first hand experience with this developer? The little out there was people loved it on the t grain films as it really controlled the highlights but was no longer produced and many were disappointed and moved on to other developers. I have a couple bulk rolls of tmax and delta so sounds like a promising developer.

Thoughts?

Even if it works, you will have trouble finding more. Why not accept the inevitable and move to something current?

I used to use a lot of FG7, but decided to start mixing my own developer when that went away.

TG7 was my mainstay when I was shooting a lot of TMax films. TG7 has been off the market for probably over 20 years now. It did not have tremendous keeping quality when it was available new (open the bottle, and within a year it was kaput). TG7 was basically FG7 with an additive, anyway. If you are curious about it, take a photo of/copy down the ingredients list from the bottle in the store and brew your own. It's just another Metol HQ developer IIRC.

I have d-76, hc110, diafine, acufine, tmax dev and rodinal here. Just curious about it as hate to see it just sitting on a shelf only to end up in a dump.

The fact I'm shooting a bunch of tgrain right now is what intrigued me but not if it won't keep. Probably will just pass on this.

Thank you both for the replies.

The ingredients list on the bottle is not detailed enough to reproduce the developer.

Jon I realy can imagine what your intention is.But if you may find no way to get your stuff - there is allways an alternatate.
What about other developers of Edwal type. There are some formulas I personal remember. Do you see a chance to try out one of these?
Sure - then you have to work with homebrew developer.
But I might also remember an Edwal type
from fotographers formula ???
The next method for you could be to focus in the characteristics of your beloved Edwal TG7 ! There are other developers in the near. So as some recomandations from here.
But then you have to say good by to Edwal?

with regards

PS : Come on - have a try!

PPS : If you can't live without you may start own research. If you trust yourself.
But Edwal has had the advance of many years - so this could be the extremest task

Sorry (wrong translated) - you got the stuff in expired condition?
I can't say - but you should shot a test roll of 135 film and soon you will see.
Perhaps you cut your test film in parts and develope this with all developers you bought.
I personal Do Not buy old chems as liquids - but old expired powder developers are welcome.

with regards
