What is ISO? ISO Has NOTHING To Do With Exposure!

What is ISO? How does camera ISO work? How does it affect exposure? This photography tutorial explains these concepts in simple to understand language. NOTE: ISO is a very complex topic. Some of the ISO exposure and light settings have been simplified for clarity.

ISO is a complicated topic. Hope this helps. Feel free to share any ISO tips below.

pal2tech My man Chris! Went full Wayne Szalinski lab coat mode at the end of this clip hahah. Glad to see u back at it man!! A quality video, well done! My best ISO tip is more lighting lol. In all seriousness sometimes you can’t. Then maybe all we are left with is “fix it in post” kind of work arounds... which would make a great segway video by the wayyy ;). As a new photographer it’s been hard to find content in the pal2tech learning style that helps with the whole “post process”; stacking, mild composite edits in photoshop, cleaning up noise, these are all foreign to me right now. A problem/solution approach is so valued and you’re def good at delivering that.

I played around with single lens reflex cameras in my younger days, but am just learning how the new fangled digital cameras work. I ignore ISO with the idea that I can adjust brightness "post production." Meaning, if my computer image is dark, I can use the software to brighten it up and lose no picture quality. Am I right?

@AndersRomin 4 жыл бұрын

I never realized before that ISO is just like the input volume when recording audio. It doesn’t make the instrument play louder, it just amplifies the existing signal. 🤔 Thanks!

ISO is input gain! Nice comparison. The noise with higher ISO photos is like the hiss of a higher noise floor from cranking the gain!

As a film guy, this is the best clarification of ISO in digital photography I've seen. Thanks!

@ChrysAureus 2 жыл бұрын

... for us old timers it was all about "film sensitivity" ASA number (usually varying between 50 and 400 ASA) and you chose your film according to the expected light conditions of your shooting setup. Sometimes you could try "pushing up" your ASA into extreme territories like 1600 or 3200 for extra dark conditions but the price to pay was obvious graininess (noise) and less contrast. There was not much wiggling room for post production corrections if you missed the right exposure mix!

@mr_mr 2 ай бұрын

Good point. I've usually thought about my digital ISO as ASA. It seems to be more like, but not completely related to push/pull. There is a healthy range of adjustable digital ISO that is natively comfortable for your camera and outside of that range it becomes the equivalent to push/pull film. OR is it that there is only one, the lowest ISO is the only true equal to a film ASA? That's where this is losing me a tiny bit.

It shouldn’t be called the “exposure triangle.” It should be called the image brightness triangle. Changing any of the corners has an effect on image brightness. You did a good job of explaining a very complicated subject. Personally I usually choose my shutter speed and aperture based on artistic choices and then set the overall image brightness with the ISO setting. Sometimes I do it manually and sometimes I let the camera choose one or more of the settings based on a range and strategy I have preselected.

@pal2tech 4 жыл бұрын

EXACTLY: Image Brightness triangle. I'm all for that.

While everything you say here is technically correct, most of my students are only concerned with the camera's inputs and outputs. From their perspective, the "effective exposure (actual exposure + ISO)" IS the actual exposure. So, heuristically, there is a real advantage to treating ISO "as if" it were a third exposure variable. The exposure triangle is just too good a teaching tool to ignore, at least early on. Excellent video! Thanks.

@pal2tech 4 жыл бұрын

Yes, I think the Exposure Triangle should always be used to explain this. I just wanted to dig a bit further under the hood in how it's affecting the sensor vs. aperture and SS.

Just finished this awesome video it's good to see the information broken down in a usable way. I did one year of shooting where I set the iso at 400 and did not allow myself to move the iso. this one thing improved the quality of my photography by leaps and bounds. This method frees you to focus on composition lighting and motion capture. Liberating is the only way to describe it. I would recommend at least a few weeks of intensive shooting at a fixed iso it's a good look inward. Thank you again for this helpful bit of information.

When I will become as good teacher as you, this is how I will teach my students: ISO is not your friend! ISO is that compromise that once you optimized aperture and SS allows you to gain some brightness in trade with noise. This is how I have been seen the ISO for myself, as last tune once I could not get any more exposure through A and SS

This is a great explanation for why in certain situations I will, in a situation where available light cannot be managed (action nature shots, for instance), underexpose a photo with my digital cameras because I can push the exposure in [Lightroom] after the fact using its 'algorithms / amplification' bits and widgets rather than pushing the ISO in camera and using its 'algorithms / amplification' bits and widgets... doing it in post is sometimes preferable (again, to 'me') because I can control it very specifically and very precisely in post.
