What Aperture Gives The Sharpest Print?
Вставка
- Опубліковано 7 вер 2024
- This week we are going to cover how to determine the sharpest aperture to use while printing in the darkroom. Not all f/stops are the same, some leave the image a little soft, some introduce diffraction, and some are just right. These are easy steps and you should have your answer in just an hour or two.

Thanks for this video! Your test shows the differences very clearly - I'm amazed at just how dramatic the differences were between f/2.8 and f/5.6.
Me too actually
Nice to see you do all these tests so we don’t have to 😊
I realised how lucky I am using the intrepid enlarger as since the last update I can change the led brightness (taking my prints from 2 seconds to 7 currently).
I generally avoid going over f/11 on cameras but it’s interesting to see that f/11 isn’t a hard limit
That's not an enlarger 😂
Good to know that I don't lose anything by printing at F11 or F16 mostly. I enjoy having longer exposure times because it gives me great control when dodging or burning in.
Thanks for this test, will do this once I receive my Intrepid enlarger with my Rodenstock N's.
And longer exposures times gives a nice window to hit the right exposure and remove effects from handling your paper/enlarger.
Good to know. I've kind of figured that stopping the aperture down would yield a sharper image. My mindset being that it would work like a camera lens by having a larger depth of field and less chance of stuff being out of focus. And this at least confirms that the high aperture yields better results to a point.
I've been using f16-f22 because of this, but also because my mechanical timer is not always precisely the time I set it. The precision can vary up to half a second, sometime a full second. So, I expose longer to minimize that error. Good to know that the aperture settings I'm using aren't adversely affecting the image quality.
I generally try to keep my exposure times between 10-20 seconds and set the aperture accordingly. If I find that my aperture ends up at f/16 or f/22, I’ll put a piece of diffusion between the negative and light to cut down the light and let me open up the aperture so that I’m in the f/5.6-f/11 range.
Very useful, especially as I use the same 100mm for my 6x9 enlarging
What a great channel and great content. Definitely helping me along as I'm getting into darkroom printing.
Thank You. Great as usual 👍
I feel like f/11 while not "sharper" was a bit tighter, especially on the V. I think f11 is the peak sharpness.
I stop down to F22 when dodging or burning is required. Give you more tine
Great video! I would love if you could do one showing what the different contrast filters do when dodging and burning. I am still trying to grasp it.
Like my split grade printing video?
@@TheNakedPhotographer Kind of, but that video (though great) didn’t really show the effects of dodging and burning with different filters. Like how different it is to burn in clouds with a Grade 0 vs. a Grade 5. Just an idea.... Thanks for all the hard work!
Interesting results. Interesting to compare with Ctein's tests in his book 'Post Exposure'.
I have the book, but not looked to see. And I think I used different lenses than his tests.
Great content as always
The shave looks great! Cheers.
Enjoy your videos - really appreciate the time and effort you put into them - thanks.
BTW shipping to Australia doesn't work either :-(
I will have to check with my store service provider
Hi there and happy new year. How do i search your channel for video on how to get the best tonal black and white. I was about to right “contrast” but im not sure that what im looking for. Actually i gave up on printing black and white because i allways ended up getting some very dull prints despite i was trying to print splitgrade printing eith nder the lens ilford filters. Mabey im not good enought /aware of the photograph in it self.. i mean howit is exposed …i guees it all starts with the photograph … anyway , now im ready again to try to get some good black and white pictures and prints but i need some good advices and some of your great videos to start on. Kind regards jesprt
Love the video, and greatly enjoyed the proof of concept of both this and the last video. I do have a theory question. What are your thoughts on using an enlarger lens for the next larger format when making enlargements? I.E. using an 80mm lens for 35mm film. Do you think it would help to reduce diffractction in the corners of prints at smaller apertures?
I use the 100mm for 35mm and MF film since it’s easier with my big enlarger. With low quality lenses it can avoid soft corners, but with good modern lenses it doesn’t matter in my opinion.
Hi, I guess I'm 2 years too late to be in the running to claim on of your medium format target negatives...can you please point me to where I may order some online? Thanks!
I got mine off ebay
👍🏼
Hi there. Ive been printing color for some time using your great videos and ive gotten some very nice pictures for my walls in my home. What i need , i think, is to get some more contrast in my prints and ive been using
hydrogen peroxide as you describe as a quick and easy way with some results. Now im thinking of getting a better enlarger lens ( actually im quit satisfied with the one i have now in terms of sharpness ( rodagon 80 mm 5.6 ) but maybe a better / more expensiv lens can boost the contrast more) . So my question is : do you think that this can display a visible difference in contrast ( ive been looking at some rodenstock apo lenses for 6x6 ) kind regards jesper
Do you develop your own film or have a lab do it? You may try developing a little longer to increase contrast, but I would only try 15-30 seconds longer. Another method is making contrast increase masks. That is time and labor intensive.
Yes i develop my own film and never thought about that. So i will try and folllow your advice here. Thanks again for all your fantastic help and great videos. 👍
I'm trying to purchase test negative from the UK PayPal says no. Guess they have probably all gone now. Will just have to see if I come across any here in UK.
Something is going on with my online store but their tech support isn’t available on weekends. I’ll have to talk to them tomorrow
@@TheNakedPhotographer If it helps sort things out, your site comes up as unsecured.
a pity, that you do not deliver to germany :-(
I’ll recheck the shipping settings
Try it again. I’ve changed the shipping settings. You may need to clear your browser cache too
@@TheNakedPhotographer still not seems to work :-( tried also a different browser ...
Message me through Instagram with your email and delivery address and I can figure up a PayPal invoice
@@TheNakedPhotographer it's gone now anyhow. Thanks and have a great weekend ;-)
keep the beard, it boosts the immune system.
Ups, I tried to get one of those test negatives but the website said that you do not ship to the UK. Sadface.
Weird. I have international shipping set as an option on my end. Clear your browser cache and try again
@@TheNakedPhotographer I am gonna try again using my phone. Perhaps my browser is messing with me or with your website.
If it still doesn’t work for you reach out through my Instagram and I can help you out there
Nope, I believe that is your website. I cannot access to the delivery options prior payment, and in the payment stage says that you do not deliver out of the US. Strange...
@@TheNakedPhotographer you got a message. ;) ahahah
Nooo the beard has gone
It migrated to my back for the summer
@@TheNakedPhotographer LOL
