@@michaelangeloh.5383 Actually, 8 years later there is still no information on times (math) for fulling film per stop of overexposure. Pushing though there is a plethora of it

You have a book by Bruce Mau! I love his work, he designed some thing for my father back in the day, they've been friends since he was in school.

Just getting into shooting medium format and this was extremely thorough and helpful. Thank you!

It would be great to see the difference when pushing/pulling film, so hopefully you can get around to that video. Well explained, thanks.

Love this - more film goodness from Ted. Thank you for this video!

So simple. Thanks

I think another advantage or real use case of pulling and pushing is adjusting light level: e.g. you have light and shadows to far away such as in an indoor scene with a window and you want to take a picture which shows the inside view of a room and the outside view from the window pulling will help you to make that possible. Pushing will help you get a more punchy picture if you only have flat light available. So it is not only for low light circumstances.

Thank you for providing clarity on this subject. I myself am new to film photography and need to get the basics down.

Thanks for another great video! I've been getting into 35mm photography lately and your videos are a great resource.

Awesome video, Ted! Finally found a person to explain this to me and I understand! Thanks so much!

Your videos are really great Ted. Very helpful and informative! I especially love the ones you made on Saul Leiter, as I'm a big fan. Can you recommend any photographers that are a little similar to Leiter?

can I ask, for film cameras, how do you metering films with different ISO? when metering, does the camera consider all films as certain default ISO? 100/ 400? e.g. canon AE-1 metering for ILFORD delta 100 and ILFORD delta 3200? is there any formulas we should follow? thanks

Thank you! I finally understand! You answered all the questions I’ve always had, ty again!

Thank you I have been wondering about pushing & pulling film.

I shot Portra 400 at 3200 at a show the other weekend along with Fuji C200 at 1600. In fact if I know it's going to be low light I always push films like these. They will be grainy, but it's pretty and I like the richness of the colours and textures that can't be imitated with digital presets as much as they try (even if they could I wouldn't, one medium imitating the other is tacky to me. I love both for the record). I sometimes push when there is bright daylight even. However, I do not develop pushed or pulled rolls myself, I use a fantastic lab I mail to for that. If I shoot box speed and I can follow the recipe then I develop my own. Sometimes there is an image I know I don't want to risk ruining. It'd be interesting for you to do a video on 'grain aliasing' regarding scanning certain films, especially pushed/pulled, I don't know if it's a 'thing' but I'm beginning to think it is. I aquired an old Nikon LS-2000 recently that might do this, the scanner mildly accentuates the grain perhaps,. I'm not sure yet. Obviously if you zoom in the grain becomes noticeably pixelated at a certain point and this must affect the tonal range somewhat (though I'm still impressed with the amount it picks up uncompressed from a refurbished 20 year old obsolete film scanner than a recent upper range flatbed say), but those old Coolscans really reproduce a faithful image compared side by side with the prints I've made in the dark room, but there is a noticeable difference in fineness. I think you could just about get away with a faithful looking 40 inch wide print depending on the printer before it became unsightly. I've not printed anything off from it so far, just used the measuring tape against the monitor. Anyway, rambling on. Shorthand here is you're underexposing the negative then pushing (over developing) the processing time, pulling is the reverse overexposing and under developing. With pushing the underexposure will lose you shadow detail hence the contrast while the highlights may be blown from the over development, the pay off is the gorgeous over saturation of the mid tones from it 'soaking' in the chemicals longer. That's my understanding at least. I had a friend who thought she was 'pushing' film for years just by rating it differently, when in fact she was just underexposing it and having it developed normally. I did a mental face palm when I realised. They came out ok though! One stop here or there, I'm completely loose with it myself sometimes. Some films have loads of latitude.

Hi Ted, I need your help and experience :) do you have any ideas on develop times (20 Celsius tank process, Fomadon R09 developer -similar to Rodinal- 1:25 dilution), when i got 2 35mm rolls of Ilford Pan 400, exposed @ Iso 100, so I need to pull 2 stops. this is the first time i've ever trying something like that, so i thought you have some experience with these negatives and develop times! Thank you :)

Excellent explanation - Thank you!

Slide films can also be pushed / pulled. I regularly shoot Fuji Provia 100F at 200 and push +1, the results are fantastic and almost no different to normal. I even sometimes shoot it at 320 and have it pushed +2 stops and the results are also very good although the contrast gets very high.

I have pushed Tri-x allot. I love that film. Yes if pushing you are committed to the whole roll, but I heard there is a way around that by instead of rodinal, using Diafine. Any thoughts on that Ted or others... Greg

pushing and pulling is the best reason to shoot sheet film. thanks great vid

Sometimes people use EI to indicate Exposure Index rather than Exposure Indicator. I'm not sure what the official expansion of I is but whether indicator or index, it is what the film was actually shot at.

Thank you so much for this video. Now the EXIF data for medium format cameras makes so much more sense to me, when viewing shots on Flickr. It would really be cool if you did a video on what some of the EXIF, Tags and Info that Photographers include on Flickr means... I'm having to learn the hard way.

It was very helpful and informative. Thanks!

ASA= American Standards Association ISO= International Standards Organization You make a distinction between ASA and ISO. The ASA film speed is exactly the same as the same number ISO film speed. ISO just replaced ASA. Tri-X has an ASA film speed of 400 and it has anISO film speed of 400. You do not set the meter at an ISO number and then take pictures at an ASA number. The only time you have to ever think about ASA is if your cameras are marked ASA at the point where you set the film speed, or if you are reading old photography books/magazines Tri-X shot at a meter setting of ISO 1600 and developed in Diafine used to provide an acceptable speed increase with fine grain without suffering from increased contrast. Many of my college bw photography assignments were developed in Diafine.

Oh, and not being able to change the iso for the entire roll of 35 mm... you can note how many exposures on a partially shot roll, re wind it ... helpful if you stop rewinding when you feel it pull off the take up/ crank side so the already exposed leader is at least partially out. My f6 can be set for that or use an extractor if wound into the cassette. Mark the cassette for iso and # of shots. Reload another roll with a different iso and you have changed iso. You can re load what was the partial roll, put on the lens cap and cover the view finder/go to f/22 1/1000 and start firing off frames til you get one past where you left off as insurance. You can then shoot that at the iso you had used. So in fact, you can change iso, just not on the same roll.

Thank you for explaining this!

so what about if I push the film for a shot that I need more light (in a shadowed alley let's say) and then I need to shoot a sunny scene and set the ISO to film standard (same roll of film)..Is that doable or it's going to ''ruin'' the photos?I'm confused or just stupid

Thank you. That was very clear and helpful. I'm returning the Kodak Portra 160 (mistakenly sent) in exchange for the Portra 400. I'm excited to try it out. Does the same "side effects" happen with color film or just black & white?

I really like to push Tri-X 400, to 1600. The the prints are a lot more interesting, with a slight grainy feel. KG

Because of exposure latitude, Ilford XP2 for example is very good for this.

So i recently shot a roll of ilford 100 at 400 accidently, That means i push process when developing 2 stops correct?

Makes a lot of sense! Thanks for your explanation!

I've heard a couple times about pushing C-41 film. does this work too?

Hi when you modifie the ISO on digital it ils the same thing that you are doing in film, you amplifie or reduce the signal that you have in the raw file , same as pushing/ Pulling when you develop film

Thank you for this clear explanation!

ok.. I have a question since I am a bit confused here with the explanation. If I wanted to push 400 asa film to 800 doesnt that mean that I need more light since the 400 speed film is less sensitive than 800 asa film? At 800 a film is more sensitive to light meaning it needs less exposure time. Again, thank you for taking the time in addressing my question and thank you for the video

if you correctly metered on your subjects, assuming they're backlit, I'd have the lab pull one stop. -1, so your 400 box speed film was rated at 100 (-2) but I'd have it developed as if you rated it at 200. Your shadow detail should remain, and the highlights shouldn't be clipped. TriX has great latitude, I'd honestly just pull 1 stop.

If it's color film you don't need to tell the lab anything. If it's black and white I would specify. For example the times for processing Tri-x @ 100 and @ 400 are about a minute or two apart and I've seen it mentioned online that it makes little difference but I have tested this myself and can tell you the difference is quite significant and could potentially ruin a great shot.

Hi Ted, im new to this. If i shoot at 1600 on my 400 film, i bring it to the lab and push the film to 1600 means entire roll is developed in 1600. What if some of the photos in the negative i can see they are overexposed can i still pull them back to 800 in postprocess? - i think it's possible but the grains and strong contrast will still be there. am i right? Thanks

So if I want to shoot at night and shoot iso 400 film @1600, then should i develop it at 400 or 1600?

Awesome video, thank you so much!!!

I am probably a bit late with this reply but the only developer you can use for a 5 stop over exposure is Perceptol. Do a clip test at about 6 minutes in stock solution at 20 deg.

well explained - i was trying to eplain it to a friend in a facebook comment - i gave up and used this ;)

Hi Ted. What do you think of Ultrafine xtreme film? it's consumer film.

So if I'd shoot the same scene with a 400 Iso Film @200, then again with a 100 ISO film at 200, there'd be differences in contrast. Is the grain comparable then though, or is there still a huge difference between the pulled 400 and the pushed 200 film? thanks !

you can change push/pull the film frame by frame if you develop in stand dev. i do it all the time...

So are you pushing or pulling the negative or the print?

Can you push and pull according to the lighting in your photo on a single roll to ''even it up''...?

You could shoot at different ISO but you will need to know what is the right frame to cut. Take your camera and find how far the first frame is cranked. Then get some sticks that you can measure the film in the dark room with. What you want to do is take one or two photos of nothing important or just leave the lens cap on. Cut the film and you will now have to develop those strips by them self. It might take a little practice to learn how to do it.

What about the change in development time? Anyone know any guidelines?

Thank you much, now i finally understand!

Hey Ted I’m from the future, just wanted to tell you that you will age very well

Hi , I have a question, you say you are committed to the entire roll being processed the same. My question involves the Apollo photos , according to NASA the first few pictures on each magazine were exposed in a controlled manner. These first exposures were then cut from the roll and developed first to tweak the development/processing of the priceless lunar photos that followed. Is this pushing/pulling ? Doesn't this contradict the committed to the entire roll statement? Finally is this why in some Apollo photos you can see a faint square outline around the earth?

@thedarkroomukltd7541

6 жыл бұрын

The technique you are referring to is called a clip test. A small portion of film is cut off and processed first to assess if the development needed to be adjusted for the rest of the film, which could then be pushed/pulled appropriately. I'm not surprised they approached it that way

If you forget to set the ASA on the camera higher (when wanting to push) can you still have them push a stop or two at the lab?

Yes. Pushing refers to the development procedure. You can technically push process underexposed or overexposed film for different tonal ranges and creative effects. What is generally referred to as pushing the film, however, is when you underexpose a film and overdevelop it to compensate.

I've had problems with grain even when shooting my HP5 at 400 ISO. I know my temperature has been consistent at 20 degrees Celsius. Can you help me with a video on temperature or agitation? I think maybe grain has something to do with those with developing film yourself? Thank you very much for the videos!

Yes, otherwise your film will be underexposed and the images will be very grainy and lacking in shadow detail.

Thanks for the video but I feel like I'm missing something. If I load a 400 film and set the iso to 800, how does that result in the film receiving more light? In my mind, that would tell my metering system that the film is more sensitive, therefore needing faster exposures or smaller apertures to compensate. Perhaps I'm misunderstanding but I had assumed the iso dial was only to inform the metering and didn't inherently change what happened to the film.

@mechanicalcanvas

Жыл бұрын

Your comment is old but I'll answer anyways. If you load 400 speed film but tell your meter you have 800. You're telling your camera the film is more sensitive than it truly is. When you take your shot at the appropriate exposure, you actually underexposing the shot because the meter is reading 1 stop more light than there really is (400 -> 800 is one stop). Hence the reason to tell the lab or yourself to overdevelop by 1 stop during development. Like wise, if you rate lower from 400 to 200, you're telling the meter there is less light than there truly is and your shots will be overexposed so the film needs less development time. The ISO dial doesn't inherently change the film in any way but it does dictate your exposure settings which will affect the shot.

Very nice video bit no one ever answers the push pull question completely . If I want to push one stop what might the average time addition in the processing be . 1 minute, 4 minutes Where do I start to get that 1 stop push effect. Also if I don't want to push it but just increase the contrast I guess if you want to just increase contrast you are at the same time pushing it even if the exposure was proper. ????

+Ronald Ergen Hi Ron. In answer to your part of your question..... If you push a film one stop, then you have to increase your box speed development time by 1 + 20% Shown as 'n+1' Which means.... if it was this simple.... that normal development was 5 min dev by adding 20% to the dev time would increase the dev time by 1 min, eg 5x1.2= 6 min dev time. However, pushing by 2 tops will be 'N+2' Which will be 5min x1.2=6 6x1.2=7.2 min. If you pull one stop then you will divide by 20%, reducing your development time to 4.167min. Clear as mud I know but stick with it and you will suss it out :-) If you want to increase your contrast at box speed then shoot one stop under exposed and increase your box speed development time by 20% and if you want to decrease your contrast then do the opposite.I hope this helps a little :-) RegardsIain

This was quite some time ago, but if you just get the film developed at the normal 400, the 800 one might be underexposed (as the shutter time was shorter, as the camera thought the film was 800 and more sensitive). - So unless you're able to cut out that one image in a darkroom and develop it differently from the rest, it might just be too dark or dim.

Pushing and pulling is a lot better if you've determined the exact film speed and development time for a partiicular film with your standard film, equipment, agitation technique and printing.

if you were to pull film would there be less contrast? since pushing increases contrast

Thanks alot for this video. I have been confused about the pushing and pulling technique. I have a canon ftb ql and a roll of delta 3200. I did read that this film is actually not an iso of 3200, but it is intended to be pushed to 3200. My canon ftb's setting of iso just goes to 1600. So, should I shoot at 1600, and push to 3200? Or just develop at 1600. I'm assuming developing at 1600 will give me a neutral look that I can manipulate contrast in post. But again, this is my "theory" so I'm not exactly sure if it will work. Also, I haven't heard anyone talk about if pushing an pulling works for COLOR film.

could pushing and a red filter work together?

Another youtuber did a test of hp5 shot from 1 stop under exposed to 7 stops over exposed. At 5 stops over exposed there was hardly any difference with properly exposed one. Try 4 stops over with digital, that is how I get a pure white background in studio and a shot 5 stops over with digital would be pure white. So much for film being hard to use. So for street, if I expose for shadows, I am ok. Also, this film at 400 is pretty low contrast and for my taste, 1600 pushed 2 stops is just right and still minor room to drop shadows. Oh, and its not expensive. My go to 35 mm b&w. MF 3200 also at 1600 so it simplifies exposure although I try to nail the 3200 on stop over exposed as it isnt as forgiving as hp5.

im new to this so bare with me.... I'm currently using 25 iso film if I push this two stops to iso 100 , I use a development time based on 100 iso fil... am I correct or just having a blonde moment.?

You are actually going to develop to your 25 ISO, and then adjust. (I'm sure you have already figured this out). The short version is pushing one stop in your developer is adding 20% time. Pushing 2 stops in developer is adding 50% to your time. There is a more detailed formula but the 20% and 50% addition to your time works pretty well.

1:00 I suppose if you shoot in RAW you could say messing with exposure in post (photoshop etc) would be the equivalent to pushing and pulling, and to a lesser extent with JPEGs. Not quite the same thing but the closest digital equivalent.

If you pull film, does that mean you make the grain less apparent from the normal exposure as well? So, let's say if a 400 film used as normal (at 400) has a certain character to the grain that is noticeable, would it become less noticeable being shot and developed at a lower ISO? - I don't assume it would disappear, but just less apparent than at normal use.

Yes. Less development time = smaller grain and less contrast

Am a little confused. If you push film from ISO 400 to 800, you set the film speed on the camera to 800. Since the camera ISO determines how to meter the exposure, you then use the camera reading to take the shot. If you are using an external meter and metered at 800, then does it matter what ISO you set the camera at?

@nicovincenti9

If you're using an external meter it doesn't matter the reading from the in-camera meter. You just need to be in manual mode and set the parameters the external meter gives you related to aperture and shutter speed. Some cameras may have an automatic modes in which they set the aperture and shutter speed (based on the ISO you set the in-camera meter or which is determined by the DX code in the cannister; which is detected automatically by the camera) and other cameras have an internal meter but you gotta set the parameters on your own. You're gonna need to research about your camera to know how it works.

400 to 800 Exposure Index is 1 stop, not 2. and if you push from 400 to 800 you will get half the light (reducing exposure by 50%), not double like you seemed to have said, if I interpreted you correctly. Now, if you develop your film as a 400 ISO instead of 800, you're not really pushing your film. The contrast will be lower and I suspect your highlights won't be that developed, because you're reducing development time AND you likely underexposed your dark tones (if you metered for the medium tones or highlights). That may result in a lower contrast than desired, with blocked shadows.. but hey - shoot, be consistent and find out what's best for you. you may find your results very pleasing.
