Good demonstration. In the 70s, there used to be at least four grades of popular papers. Soft, special, normal and hard. With varying contrast characteristics. Glossy, matte, slik surfaces. Single weight, double weight etc... beautiful times... thanks. Mixing developers is an art in itself.... ❤
I studied with Ansel Adams and I can assure UA-cam readers that your printing demonstration is one of the very best I've ever seen here. Bravo. One comment I would make (basically agreeing with your method but with a slightly different approach): I make my test prints in three-to-five basic steps. The first step concentrates ONLY on using an important white area (the lightest white which shows detail) to determine an over exposure time (which be tweeked later). Instead of moving a card to expose the whole print for my test, I expose ONLY that same white part (and, at a low contrast, such as grade 1.5) to various times by sliding the PAPER past a slot cut into a card which covers it. In that way I can compare this important white section, side by side. From here I can derive a basic exposure time for the whole print. After that I make an overall print at the best looking time to see what that exposure time does to my important dark & shadow areas, whose density I can test and control in my third test print by estimating which contrast filter will best do the job. I can normally arrive at a good "first" print after about five test prints (which, to save paper, needn't be whole sheets!) Thanks again for your excellent demonstration.
Yes, I do the same, I even narrow it to a smaller test strips with a special mask I created. Wasting a whole pieces of paper sheet just for testing is not an option, at least not for me in these crazy times when paper is so expensive. I am amazed how many people said it’s a great tutorial and I noticed no comment about paper wasted to do it.
Test strips are a waste of paper as they only show you the incorrect exposure in a small area of an image. They tell you very little about the whole image. The tonal strips he makes is not even in stops. One exposure for the whole image (or use strips of paper covering from shadows to highlights) will show how many stops you need to change the exposure from shadows to highlights. This is of course the primary function of The Zone System of exposure as formulated by Ansel Adam’s & Fred Archer in 1939 to 1940. Just apply those principles to your print. The rules are always the same. It’s why we talk in stops not time and aperture. I understand this may be a shock. I came to this realisation when I began teaching darkroom printing at the age of 47 after a lifetime of professional photography. I began teaching test strips as I was taught at college. I quickly realised that I don’t do that. I hadn’t made a test strip in decades. So what do I do I asked myself? Simple, I know the grey scale. I then got the students to make a set of small prints in stops from white to black of a whole negative and there is your reference for life. Soon you will just know. No need to repeat the process every time you do a print. This can then be transferred to knowing how much to dodge & burn when you reach the fine tones you require to make that beautiful silver print. The technician said it would waist a lot of paper but on the contrary it saved a lot of paper and also taught the students the Zone System of exposure. This is what I made in my darkroom…… www.hagsphotography.com
Sir, I have watched this video 10 years after you kindly made it for us. Thank you for taking the time in sharing this and I am off to my darkroom to implement it. I wish you well.
Thank you for watching! Luckily printing technique did not change in the last years, so the video is still "up to date". :) I wish you better prints and fun in the darkroom!
I second that, very nicely made video, clear explaination of the concepts, could we have some more please ? Books are good, to be shown is better. Thank you
That was quite possibly the best explanation and tutorial in making a test strip I've seen on UA-cam. Thank you so much. Can't wait to see the rest of your videos.
This is the most useful darkroom video I have watched. Your explanations are clear and concise especially the part about getting the test strips. Well done and thank you!
The point at 10:30, about correct highlight in 1 exposure and the correct shadow in the other is the first objective description of picking correct/incorrect contrast I've seen on youtube, thankyou! (Obviously, it's still subjective, but adjusting contract filters makes a lot more sense to me now)!
most would not bother to go through the 3 contrast attempts, but this video is fascinating as you explore the 'correct' contrast through trial and error. thank you!
I was taught very basic darkroom technique at highschool. This is how I've always done it. Your video has completely revolutionised my printing! Wow, thank you!
As much as i simply love the technique, your amazing teaching skills and the result i can't help but thinking those test pieces were also amazing artworks.
The absolutely critical phase, which Mr. Calabresi touches on, is evaluating the whites - or highlights - determined by exposure (+usually much lighter than you think). Dialing in contrast for the blacks is relatively easy. Developing judgement to evaluate the highlights is pivotal - otherwise you will be turning round and round, like a dog chasing it's tail, as I did for many years, so I harp on it. Split grading while doing whites first is a good way to develop this judgement.
+Igaluit I am sorry, you missed the point. Yours is the old approach that suits graded paper. The statement - exposure determines the whites, contrast the blacks - is not true on multigrade papers, hence the need to find a method to determine exposure and contrast at the same time, as I show in this video. Your approach could only work with a condensor head and contrast filters IF the tone that does not vary when changing contrast was a highlight, but the tone (when it exists) is not so much a highlight and it is not so stable. You can see it clearly on the characteristic curves of papers, where the curves of the different grades tend to cross each other at densities of around 0,5 (and not so exactly), that's more a midtone than a highlight. The approach I suggest works with any paper on any enlarger. I am not a fan of split printing. Split printing makes it easy to get a work print, but afterwards it is simply double the work. I am not a fan also because split printing is a procedure and not a method and this means that you don't need to understand how things works to make a (work) print.
Thank-you for taking the time to explain this for me (and correcting my misconceptions), especially since there are few experts now of this arcane art. What we find in old photography texts is so often cursory and even misleading. I had nagging doubts about the highlights as a focal point and was more or less reverting to looking at the general aspect of the print. What you say about split-printing is true; it's sometimes a lot of work. Also, it seems to give a very distracting sheen or shine to the image. Still, on very difficult negatives I seemed to get better results. I prefer straight printing if I have a choice. I have never seen the methodology you teach before having seen your video. The beauty of your method is that it immediately orients you in the direction you ought to go - minus the endless tries and the going around in circles. Am looking forward to trying it. Thanks again for the feedback. Mille grazie.
Reading AA's The Print, you both evaluate correct contrast in the same way, but your way is a measurable, easy to follow method with a nice demonstration and explanation. Thanks very much.
In the past 12 months I have started shooting and developing my own film. I have recently purchased an enlarger to learn to make my own prints. Fantastic explanation, you are a great teacher. Thanks for taking the time to do this video.
Excellent tutorial. I learn something new every time I watch this.👍

thanks a lot Mr Calabresi for sharing this method of finding the best contrast for a print. I've always struggled with contrast while printing. Really appreciate your kindness on sharing this. Best wishes, Santiago
Mr Calabresi, thank you so much for your dedication to your art, the outcome of which is this very informative gem of a video! And thank you for your kindness to share!
Andrea! Many thanks for taking the time to share your skills and expertise. I am just setting up my first dark room and there seems so much to learn. Thanks again for your help in your video,so well presented and understandable. Regards Ken
Very useful insight about contrast control on printing. Thank you very much for your video. Looking forward to more videos like these. Regards from Greece!
Thank you for sharing your technique, this is greatly appreciated! I've always been doing actual test strips by cutting up photo paper and exposing several single strips - then developing. This makes so much more sense and the work process feels much cleaner.
+Jakob Reisinger, it seems to me that you get a better reading by exposing a full sheet and in the end actually save paper by not having to keep printing with each adjustment. This method looks pretty accurate and I'm excited to give it a try. Best of luck in your work!
Congratulations. This is a great darkroom tutorial. Excellent in every detail, technical and not only,... including the tone of your voice. Really superb. Thanks
Very very well explained. Some expert just say my feeling is to use this or that filter, but you explain why the filter you use is higher or lower. This helped me alot
What an excellent tutorial. I figured out more about nailing contrast in fifteen minutes here than a year of photo school and four years of sporadic darkroom practice (...and googling, forum-ing, book reading, etc. ...)!!! Any more tutorials coming???
Thank you for a very informative video Andrea! I can't wait till my next day off so that I can go into the darkroom and put this new knowledge to use. :-)
Thanks for chiming in so quickly. I will say the split grade works very well for and a lot success in tough negs situations. Like bullet proof skies like we have here in New Mexico. I do float between technique simile it to yours in low contrast negs and the other. Thanks for posting. Your technique is another tool I can use in my darkroom tool chest.
+ToddB987 I know. That's exactly what I intended about non optimal negatives quality and use of split printing. Why don't you reduce film developing times instead of saving them while printing? The results will be dramatically different and the freedom in print interpretation will be saved. The newest T-grain films can accomodate some 20 stops of dynamic range even on grade 2 if properly processed. BTW, Which light spource are you using in your enlarger, condensor or diffuser?
Condensor on 120 and diffuser on 35mm. I usually develop film on recommend manufactures recommendations. For example using Delta 100 developed at 12.00 min at 68 degrees using D-76. I know less time reduces contrast and more time adds more. I usually shoot a lot of varing light situation on a single roll that's why I use manufacturers recommend times. I usually shoot a lot of black and white film with a orange filter on most everything.
+ToddB987 Hi, this time I am late... Ilford developing times are generally producing negatives suitable for low contrast scenes to be printed with diffuser enlargers. So development times should be reduced (sometimes a lot) when printing with a condensor head, and/or shooting high contrast scenes. This is normal. I warmly suggest you an experiment: do dev times "bracketing" combined with exposure bracketing. Make the same images on three rolls of film (if you have a MF camera with film backs it's easy), expose with bracketing and then process for 50% 75% and suggested developing time. Finally print it all.
Just learned something. I have been leaving my print in the developer until the time was up. He takes it out a few seconds before and then waits for the time to end. Will start doing that tonight.
Wow This turned on the light for me. It's really quite simple when someone explains it in simple terms. Thank You for this. I'd like to see you explain the change of enlarger f stops and the results obtained. Thank You again
+EFD620G Hi. Glad you appreciated. Changing enlarger f-stop will affect exposure the usual way: closing one f-stop will require double the exposure. E.G. if the exposure is 12" @ f:8 it becomes 24" @ f:11. This follows the main exposure rule (reciprocity) wich says: E=txl - exposure= is time per light. Less light, more time and viceversa. Lens performance is also affected, but with good lenses this is visible only on higher magnification (bigger prints). Generally speaking the intermediate f-stops will yeld the better lens performance. It is advisable not to use the lens wide open or fully closed. For best performance every single lens shall be tested individually in a perfectly alligned system and at different magnifications. This requires equipment and expertise.
incredible, your clarity, simplicity of explanation and clear love for the subject are remarkable. So pleasant and instructive to see this. Thank you so much!
Yo, no shit this vid bangs hard. Cool technique with the contrast homeboi, I heard some guy said if I wanted more contrast I had to stick the print in the freezer but this makes more sense.

+mefourb Thank you very much. An expert appreciating is, indeed a great compliment. :)
NB. A more technical answer is above.
So you make the first test without filter?
Yes, I do the same, I even narrow it to a smaller test strips with a special mask I created.
Wasting a whole pieces of paper sheet just for testing is not an option, at least not for me in these crazy times when paper is so expensive.
I am amazed how many people said it’s a great tutorial and I noticed no comment about paper wasted to do it.
