It is a non-solvent developer, but not all non-solvent developers are high acutance, though all high-acutance developers are low- or non-solvent.. For those who want what Rodinal is supposed to offer, I suggest FX-39 II, at 1+14 dilution, using the times for the 1 +9 dilution. See: https://www.catalinsamoila.com/perfect-developer/ From the Adox web site "Rodinal - ACUTANCE ENHANCING FILM DEVELOPER" and "FX-39 II - BALANCED GRAIN, SHARPNESS AND CONTRAST" From the Catalin Samoila site quoted, speaking of Rodinal, "Its most appreciated parameter is acutance, although much later I discovered that it is only apparent and is useful only for magnification on photographic paper." It sounds like she is confusing acutance, where in my experience Rodinal excels, with sharpness, where Rodinal is only average.

Aryel Posted October 17, 2021 Author Share #22 Posted October 17, 2021 I found one more reason for me to try Rodinal: I don’t really grasp the difference between acutance and sharpness. I am hoping to understand by seeing it on my photos. 1 Quote Link to post Share on other sites More sharing options...

Think of acutance as an increase in edge contrast, making edges more defined, but not actually sharper. 1 2 Quote Link to post Share on other sites More sharing options...

FX39 is far superior to Rodinal in every way. Quote Link to post Share on other sites More sharing options...
oldwino Posted October 17, 2021 Share #25 Posted October 17, 2021 Use 1+50 for a more normal contrast. Use 1+25 if you want negatives that really pop. Slight overexposure seems best. Also, VERY gentle agitation, as in, just gently turn the tank over once each minute. Otherwise, you’ll have a whole bushel of grain. I sometimes agitate once every two minutes this way. There are probably “better” developers, but nothing gives you the look of Rodinal. It’s unique. And often, for many, “better” just means “bland” or “boring”. 3 Quote Link to post Share on other sites More sharing options...

And often, for many, “better” just means “bland” or “boring”. Haven’t received the developer yet. I shot two rolls of trix400 exposed @200 and one roll of fp4+ exposed @100. Trying to find recommended starting point for the trix. Massive dev chart indicates 9 minutes (1:50) with 10 sec inversions every minute. Was thinking to do only one gentle inversion every minute. 2 Quote Link to post Share on other sites More sharing options...

Not quite sure how your reply pertains to understanding acutance, although I think we all understand by now that you dislike Rodinal. To which I have but one answer: Welcome, dear visitor!

There are some advantages to having a fridge reserved for storing chemicals! Some products achieve 'cult' status for no particularly good reason. Sometimes there is a lack of technical sophistication, as in those who prefer 'vinyl' to CDs. Rodinal is one such product. I do not for the life of me understand why anyone uses it. 1 Quote Link to post Share on other sites More sharing options...
chrism Posted October 18, 2021 Share #29 Posted October 18, 2021 You got me - I love my LPs! But really, you should let us wallow in our lack of technical sophistication. We get to do what we like, and you get to feel superior. Otherwise this thread is hardly going to turn out encouraging for the original poster. 2 Quote Link to post Share on other sites More sharing options...

Aryel Posted October 19, 2021 Author Share #31 Posted October 19, 2021 Hello, I am really thankful for the tips and advices that I received about Rodinal. @Ornello, thanks for suggesting fx-39 instead but I hope we can keep the thread on track with development tips, fun combinations to try and so on. In the mean time, I found quite a few interesting threads for rodinal wannabe 😊 Quote Link to post Share on other sites More sharing options...

I think there are far better developers than Rodinal for many jobs, FX39 being one of them. But better at what? Everything has to line up with the look you want, matched to the film you choose and the developer you use. Threads like this help in understanding why to use Rodinal although I appreciate it is too often seen as a miracle cure and the buzz words acutance and grain sharpness are often mistaken for 'more is better'. 1 Quote Link to post Share on other sites More sharing options...
Aryel Posted October 22, 2021 Author Share #33 Posted October 22, 2021 (edited) I processed my 2 first rolls yesterday and scanned a few images doing exactly the same thing as with dd-x (same sharpening). summicron v1, trix in rodinal 1:50 Welcome, dear visitor!

chrism Posted October 22, 2021 Share #35 Posted October 22, 2021 I think the OP has done well. We all know by now that you hate Rodinal. Leave him/her in peace to get on with it. It's hardly a mature attitude to keep on criticizing the OP. 4 Quote Link to post Share on other sites More sharing options...

Unless the photographer wants it to show grains. It is all about choices and intent. However, one has to take the time to experiment and learn first. I will try to scan the print, I like it actually. The grain is very visible but in a subtle and beautiful way. 1 hour ago, chrism said: I think the OP has done well. We all know by now that you hate Rodinal. Leave him/her in peace to get on with it. It's hardly a mature attitude to keep on criticizing the OP. No worry, it will take more than this to discourage me. Beside, I am having fun. Next TriX will be at 1:25 to see the difference but I have a few more to print first. Edited October 23, 2021 by Aryel 1 Quote Link to post Share on other sites More sharing options...

Aryel Posted October 23, 2021 Author Share #39 Posted October 23, 2021 (edited) I think it worked very well for this one (this is a scan of the print). My main issue with this one is that I mis focused the eyes a bit 🙃 Welcome, dear visitor!
