Comparing Kodak TRI-X and Ilford HP5+ with the Heiland Electronic TAS film processor
This video is about the visual differences between Kodak TRI-X and Ilford HP5+ using the Heiland Electronic TAS film processing unit for developing.
Both films were developed using the TAS developing system from Heiland Electronic. (heilandelectronic.de)
Developer used: Adox Rodinal, dilution 1+25, 20°C, 7 minutes and 30 seconds.
Inversion type: Inversion/rotation for 10 inversions in the first minute, then 3 inversions every following 30 seconds.
Other chemicals: Ilford Ilfostop at 1+19 and Ilford Rapid Fixer at 1+4
Paper used to make prints: Ilford Multigrade RC Glossy for contact sheets and Ilford Multigrade FB Classic for test strips and final prints.

Honestly I’ve been developing for such a long time but never heard of this ingenious device. Thanks for sharing, mate!
This was definitely one of the best videos I watched about developing.
We've heard about thin and thick negatives. What we really need are juicy negatives. That is such a great video, man - it is so nerdy and genius. Thanks for the darkroom test too!
Extremely thorough. Best example overall.
I really enjoyed this video. Please keep it up.
Great video intelligently delivered !
Really excellent video.
This is the most thorough test I’ve seen on black and white exposure and developing. There are great videos out there but there’s usually at least 1 or 2 variables they decide to not bother with which makes the results less conclusive. I’ve been shooting tri- x forever before it was renamed 400tx. I’ve also noticed recently the rebate on my contact sheets are nearly black when I exposed the paper for max black. So confused as to what they’re doing since tri-x in 120 seems to be normal. I thought my paper developer was bad or I wasn’t developing long enough. Tri-x also seems to be at a minimum a true 200 speed film or even less. Maybe 160. Apparently it used to be marketed as a 200 speed film. My recent hp5 contacts have been near perfect at 400 with extremely bright film rebates with clear sharp text. I’m always on the fence about switching to hp5. I also gave pan f+ another go and it’s now my go to low speed film at 32iso. I’ll be bulk loading soon. Thanks for this great video. Are you shooting tri-x consistently at 200? What’s your go to development time? Mine has always been 9.75m in d76 1:1 or 7min in rodinal
wow. it's so nice to be learning about these films and the ways to control the developing not just a review of which is better. i'm reading ansel adam's 'the negative' at the moment, do you have any other books or resources you recommend about science of developer dilutions and times on negatives? or is it all just practical trial and error? i really admire how meticulous and calculated you are to the artform (not to mention, a very creative eye) thank you for your time, for these videos, for your input x
Super Video, hab so einiges mitgenommen. Congrats!!!!
Curious why you add more time for HP5 and rodinal? I use it at 1-25 at 6 minutes and find it’s great but super curious what you found the benefit of a longer development time. Great video by the way!
But how do you calculate the times in such processors for the development?
Hey! I think the film curling up might be a different factor i tried a long fixing time with tri-x and its still curling up. That being said i don’t have acces to a drying cabinet. Might that be the factor making a big difference? (I just airdry the film, with weighted clamps)
