Let’s talk about film photography Since I recently got back from my Japan trip Shot a lot of film photos there My tech reviews are still coming This is what I’ll be reviewing next, hopefully Google Pixel Stand Stay tuned Ok, now, let’s talk about film Let’s get to the point What is pushing film? I believe many of you know That you can’t change the film’s ISO mid-roll. Say … This is a ISO-200 film That is how sensitive the film is to light Unlike sensors in digital cameras Where it can vary up and downs as you demand Basically, the film is a sensor where ISO is pre-determined However It’s actually not impossible to change the iso Let’s see what I mean. For those who didn’t know … This is very basic. Photography 101. The lower the ISO The less sensitive the film (sensor) is to light If you have an ISO-100 film And you wanna shoot in a low-light situation You’ll need a longer shutter speed So the film is exposed to the light longer Hence correctly exposed images That is ISO 100, for example It’s common to shoot with higher ISO film in low light Say, 800, or 1600 What if you don’t have films of suitable ISO? Say, you only have ISO 100, and you wanna shoot in low light without the motion blur due to longer shutter speed. What do you do? That’s where pushing film comes in handy Pushing film is metering the light as if you’re using the film of your desired ISO For example, this film is ISO 200 To push 1 stop means to increase the rated ISO 1 stop. So from 200 to 400 is 1 stop. That is pushing 1 stop. You treat it as if you’re shooting an ISO 400 film. When you develop it, you develop it longer as well. Just like when you develop an ISO 400 film. For the sake of example, the following numbers are made up. Say, an ISO 200 film needs to be submerged in the developing chemical for 2 minutes. If you push 1 stop. Remember, these are only made-up numbers, I repeat. Let’s say an ISO 400 film needs to be in the developer for 4 minutes. Then when you push 200 to 400. You submerge the film for 4 minutes. Can you push more than 1 stop? Sure! 200 to 400 is 1 stop Push 1 more stop, the film will be at ISO 800. 2 stops in total. When you develop the film pushing 2 stops, just treat it as an ISO 800 film. Submerge it longer. Do you know why? An ISO 200 film needs a lot of light in order to produce a correctly exposed image. Not too bright, or too dark. But since you rate your film’s ISO higher than it originally is, say, 400, the metering will think “Hey! This is ISO 400 film. You don’t need long shutter speed to get a correctly exposed image.” If you develop it as an ISO 200 film, not enough time in developer, the image will be underexposed. That’s why you need to compensate in developing time. This is unlike digital cameras where you can change ISO between each frame. Usually when developing a roll of film (all images), the whole roll goes into a developing chemical at once. So if you rate the film at a particular ISO Keep the ISO constant through the whole roll. You shouldn’t go “Oh! It’s a little dark. I’ll set the meter as ISO 1600.” Then the next morning you change it back to ISO 200. If you push, push the whole roll. Don’t know why I did that but I like how it sounded. The effects of pushing film How does it affect the images? Let me list this out Higher contrast, grainier Kinda like digital sensors The higher the ISO, the more noise. Like I said, contrast, gets more obvious. It won’t look pale, or pastel. Let me show you some sample images. Oh! One more thing! The colors will be more saturated too. Ok, let’s check out the images. And that’s what pushing film does. You can also pull film, not just push. You can also pull an ISO 400 film to 200 as well. If you want to shoot in bright light while maintaining slow shutter speed or large aperture Pulling film may help you. Pulling ISO 400 to 100 would be pulling 2 stops. From 400 to 200 Then from 200 to 100. 2 stops in total. In this case, it need less time in developer. Just like that. And if you don’t develop your own film but send to the lab This is how you let them know. On a 35mm film canister, there is an empty “note” area you can write on To push 1 stop, write “+1” Push 2 stops, write “+2”
“-1” means pull 1 stop This is a roll of medium format I shot Lomo Color Negative 800 I pushed 1 stop to ISO 1600 I shot fast-moving subjects so I pushed I wanted to freeze motion to avoid motion blur. So I was like “Let’s go 1600” I hope you guys found this video helpful Especially those of you interested in film photography If you learned something new from this video, please consider Liking and, or Subscribing. Thank you for watching. See you in the next video. Might be a review, or my Japan trip vlog, we’ll see. I really wanna review this. It’s already plugged in so, yeah. Ok, bye!
