Ilford Delta 100 - Long Exposure Clouds - Reciprocity Failure

[@ShootFilmLikeaBoss]

This video is kind of a new journey for me into the Reciprocity Failures we have to compensate for when shooting longer exposures. I'm scratching the surface here and will eventually feel more comfortable with it moving forward. Hopefully it will help those that are also on the same journey.

[@borderlands6606]

It's great to see someone shooting and printing. Makes a change from the endless new gear tests. Ilford should sponsor you!

I've been shooting film for 45 years and I appreciate what you are doing - that's a lot of work. That's film, you have to earn your chops by learning what works, plus it is time consuming. Digital processing is like cheating it's so powerful and easier. Get a lot more pleasure out of the craft of film photography when you get it right.

[@ShootFilmLikeaBoss]

Exactly why I shoot more film Steve. Digital is great and a lot easier but I find the workflow of film more challenging and rewarding.

[@tonyrigg9182]

@@ShootFilmLikeaBoss i totally agree i could easy go back to film full stop, so so much more rewarding

[@iangordicans8763]

I much prefer film. I still get a real sense of excitement when I'm shooting with a film camera which I don't get when using a digital camera.

[@mikethomas1073]

@@ShootFilmLikeaBoss I agree. I must use digital to get paid (sports), but I've just begun the process of getting back to film. Just waiting on some Russian cameras & some film. I think film is going to get me back to "enjoying" photography like I used to. Great vids, love the channel.

Thanks for letting us tag along in your experimenting! I've got 4 35mm rolls Ilford Delta 100 for my first attempts back into film shooting and film development. I've got 4 old cameras that my son and I are going to try out. Hopefully no light leaks!

Great work Roger! Very well done indeed, and no one can say you’re not committed to your art but it was well worth the results. The best thing about your channel is your willingness to try and experiment. A great video, thank you for the work you put in to it.

Thanks Mark. Always good to hear from you.

[@jonloder]

I've been working with D100 for long exposures for years. I probably know it better than any other film in my bag. Your video was very well done. I hope it inspires others to take advantage of what I consider to be one of the finest films ever produced. Keep shooting, sir.

You have taken things to the next level mate. Four dimensional photography, based on obtuse calculations that even Stephen Hawking would not fully understand. Not sure what daemons possess your soul, to bring your photography game up to these insane and brilliant levels.

[@lensman5762]

I have really been enjoying your series on film photography. Not much is being shown about film which is the original and the most challenging media for creating photographs ( which stay in your possession and not some virtual ' cloud ' somewhere in the US ) so thanks to you for your efforts. I am sure that you know that reciprocity failure can also be caused by too strong a light source too. One of Ansel Adams's lesser known masterpieces shows this effect very well.

[@ShootFilmLikeaBoss]

I didn't know that strong sunlight caused reciprocity failure! I'll have to look into that. Glad you enjoy the vids and thanks for your contribution.

I know this is an older video but it was one of interest to me. @ 10:20 ~ I noticed a beautiful shot over your shoulder. Would have been a beautiful sunset behind the tree. Using Porta and a gradient ND or deep blue for the upper 1/8 of the frame. What do you think?

[@mjones410]

I use Kentmere VC Lustre, I really like it. The Kentmere papers are a bit faster and more contrasty than Ilford Multigrades so I do find I sometimes need to pre flash the paper to control contrast, but I still love the results, deep blacks and punchy whites.

[@ShootFilmLikeaBoss]

Yeah I like Kentmere for the punch. I also have to pre flash sometimes. I have another enlarger set up just for that.

[@iainmc9859]

Really like the moody penultimate shot of the windmill (portrait, quite dark) before you re-dodged it. It looks like the kind of location that would make a good shot in any conditions (even overcast). Still don't understand reciprocity failure though... something to do with the longer the exposure the less effect it has on the film per second??? (Law of diminishing returns?)

[@ShootFilmLikeaBoss]

Pretty much. I'm a really testing ADOX Silvermax today with long exp as the conditions are perfect. Big ass White clouds moving along with sun breaking through now and then. After my tests I'll go out on location and shoot a few.

[@anja5758]

I was shooting long exposures on delta 100 with a rule I have found somewhere in the internet (actually it was Howard Bond on Photo Technique Jul/Aug 2003). However I was scanning my negatives, but they were pretty consistent in results. The rule is: Tn = 0.05698 * To ^ 1.5755 + To So for 60 seconds (To) I get 96 second exposure (Tn). I have created an excel sheet on the phone for ease of use in the field. This rule was derived by APUG user, sorry I do not remember names, from the Bond's findings.

[@ShootFilmLikeaBoss]

Thanks for this Andrzej

Other manufacturers: "here's s vague chart and a recommendation to just kinda figure it out." Illford: "here's an exact formula to use."

[@racecarinred]

Very cool, nice video

[@briansanderson5084]

Fuji are discontinuing it but I hear Acros has no reciprocity failure under two minutes and only half a stop from 120 - 1000 seconds. I always enjoy your videos, thanks very much.

[@ShootFilmLikeaBoss]

I've read that Brian. Thanks.

Yeah this is one of the greatest things about Acros, it's so good for long exposures.

[@ytdanielle]

[@ShootFilmLikeaBoss]

Thanks Dan.

[@liz.morrigan]

I see you're using an ND to increase exposure time and mentioned maybe using a red filter, the dark red 091 should give you 3 stops and really draw out the contrast even in your heavily overcast skies, then you can stack a graduated ND on top of it to act more on the sky so you can do maybe less dodging of the foreground in the darkroom.

[@ShootFilmLikeaBoss]

Good call. Thanks!

Good question. I never have and it's something I'd like to do and show in the future. Resin is less expensive for me at the moment.

[@terrywbreedlove]

I have come to realize the Delta 100 poor reciprocity performance will be a big plus. Fuji Acros 100 and it’s very good performance. I have to use dark ND filters to get long exposures on the beach. And with them on I can’t see to focus. Delta 100 will give me long exposure times just to adjust for the poor reciprocity failure. No need for dark ND filters :)

[@ShootFilmLikeaBoss]

Across is great for no reci worries

[@jasonblake5576]

Another great video, just wondering how you metered your initial exposures when dark, unless I missed something?

[@nelxonmiranda]

Cool prayer rug.

[@tedsmith_photography]

Interestingly, I just shot a roll of Fuji Provia transparency in 120 format to capture some cityscape night time shots where I was using 6-10 second exposures. I hope they come out OK because I had not compensated for RF. Your video made me check what it is for that film, and according to this (www.fujifilm.com/products/professional_films/pdf/provia_100f_datasheet.pdf) it doesn't kick in until 128 seconds!! (2 minutes). I find that hard to believe but its in the data sheet. (Page 2 : "For shutter speeds longer than 128 seconds, exposure ad-justments will be necessary to compensate for reciprocity failure"

[@MegaSumo67]

im confused how you metered the first shot. i have heard everything from lightmeter the highlights...take average of multiple readings to take a reading then at half box speed add two stops...problem is when you ask why they dont know they say you just do

Takes a lot longer but with Ilford slower films I get a good result.

[@josebainakielorriagaarriet2066]

Ilford have an easy APP TO PHONE to take the reciprocity of their principal films in any kind of medition

[@ShootFilmLikeaBoss]

It appears to differ from ilfords "to the power of" calculations. Delta 100 at a metered exposure of 10s I calculate at 18s. That app calculates it at 30.9s. that's a huge difference.

[@werewolf164]

I´ve tried that but it gives the same results for all types of films ... "inverso" app works a lot better :)

[@josebainakielorriagaarriet2066]

@@werewolf164 What is that app? I have written in the app store the word "inverse" and I do not find anything related to reciprocity. There is another app called reciprocity but it is not intuitive to use, especially for committed moments in which you find yourself with the tripod almost balancing on a rock and you need to have all the data in one look .Thanck you
