Any answer to this? Noone?

The effect will be the same.

Exposure and processing have completely different functions, and I referring only to black and white film. In black and white film the amount of detail that is carried in the shadow areas is determined by exposure only. You cannot add significant detail to the shadows by increasing development by any reasonable amount. Shadow detail is determined exclusively by exposure. In development the shadow portions of the negative develop completely fairly early in the development part. Maybe in the first three or four minutes if you have a seven minutes or so development time - which is a fairly common time. (For instance when I was using Tri-X my base development time was 7 minutes at 70 degrees f.) The highlight areas will continue to build density as long as they are in contact with an active developer solution until all the exposed silver in those areas is converted from silver halide crystals to metallic silver. Once that is done the film will not gain density since all the silver has been converted - which by the way will render negatives that are bullet proof. So we control shadow density, or detail, by exposure and we control image contrast by film development times. That's why, if you look at the film data sheets it usually says "suggested times". Time and experience will show you that most black and white films are rated at a very optimistic ASA. There are some very technical reasons why these things are the way they are. The best advice is to do a little experimentation. If you are processing the film yourself just be sure to always do everything the same way. If you have the film run commercially get to know the people at your lab and always use the same lab. Consistency is the key to getting better negatives.

Not exactly. All c41 film is developed at the same time/temp no matter what the iso is. Changing the time/temp is what pulls or pushes the film. That’s why chemicals decide push/pull and settings decide over/underexposure. Shooting Portra 400 at 200 and having them dev normal would be overexposing but if you shot it at 200 and told them to pull it 1 stop then it would be pulling the film. They will leave it in the chemicals for less time than normal c41 developing

Pulling 400 1 stop would be shooting it as 200. Pulling it two stops would be like shooting with iso 100. Pushing 1 stop would be 800, 2 stops 1600

to answer your question. Yes. As it is literally the same film as 120. They take the film off the backing paper to process so the spool itself doesnt matter.

I’m planning to buy this for first time, so I need to buy a winder? Idk anything about these camera, can u guide me what I need to buy?

If your camera has a lightmeter and you set it to 200, it’ll read the light as if it’s 200iso film. If you’re trying to pull or overexpose then that’s what you want

Hey that’s not true at all! I have a few of Canons SLR film cameras and overexpose/push or pull film. You can override the DX code reading on your camera

@@gbonii5673 yes I know you can, but you were showing this for cinema not static photography.

@@SterlingSigurdsen this is used for static photography. I’ve never done cinematography

Depending on where you live but maybe just start by google searching for film developing in the area see if anything comes up. Certain drugs stores do it but quality is the main concern.

get the film to a lab and they will process and scan the film and send you the photos via dropbox or similar service

@@garvinkelly can I go to CVS and they do it?
