Rodinal is one of the most popular and widely used black and white film developers in the world.
It has been used by some of the greatest film photographers for its look, feel and amazing shelf life.
Often lasting years when kept in ideal conditions, you don’t need much of it to develop your film as its dilution ratios are much less compared to most film developers
My primary use of it, as well as many other photographers, has been for pushing certain films to higher ISOs using stand development techniques.
Rodinal’s performance with stand development has given me some amazing shadow detail and sharpness in images, specifically with films such as Kodak Tri-X and Ilford HP5.
The history of Rodinal hasn’t been paved in gold unfortunately..as its formula was in danger but saved due to its sale to other companies a couple times
Here is some quick info about that taken from Wikipedia:
Rodinal has for a long time been manufactured in a chemical plant in Vaihingen-Enz owned originally by Agfa. In November 2005 the plant was sold to a&o Imaging Solutions GmbH in Koblenz, Germany, who continued the production of Rodinal. In 2008 it was sold again to Connect Chemicals (Ratingen, Germany.) Today Rodinal can be obtained from ADOX Fotowerke Bad Saarow, Germany. It is now called ADONAL.2
While surfing the inter-webs, studying as always, and looking up cost effective techniques, I came across a website channel called Dr. Frankenfilm.
It included a youtube video that appeared to show the ingredients and steps on how one can make DIY (Do it yourself) Rodinal.
Here is the video below:
Annnnndddd so of course I went out and purchased these chemicals to attempt to see if this was indeed true
I searched for other users’ results using this technique from Dr. Frankenfilm but was having problems finding any that confirmed their Rodinal was made with this specific formula…this lead me to try it myself
After some time, patience and making sure I safely mixed these chemicals without blowing myself up, my chemistry was complete.
Fast forward and It has now been 72 hours, the recommended time you need to let the mixture sit before using it.
I poured out the mixture as i prepared to test it
To my surprise the homemade Rodinal is the same pinkish/purplish color as the one I’m used to buying!
I began by taking 3 35mm rolls, one of Ilford Delta 400 and 2 of Ultrafine Xtreme 400, and also 2 rolls of Ilford HP5+ 120 from a recent photo shoot that i did with my beautiful friend Mondee and prepared to develop
1:100 Dilution for 2 hours, agitation only for 1 minute in beginning.
I’d like to share the results with you now
These are from my Pentax 645 with Ilford HP5+ 120:
These are taken with my Nikon F100 35mm with Ilford Delta 400 and Ultrafine Xtreme:
I was amazed at the results..and STILL am!
I can’t wait to do more shooting just on the principle that i now have the ability to make my own Rodinal from scratch and really embrace the fact that it is possible
I’m very glad that i went through this experiment as i see myself utilizing this technique more and more
Thank you everyone for checking out the blog once again and HAPPY SHOOTING!
Remember to keep progressing with your photography and to experiment as much as you can
