Why You Need Perfect Exposure in Digital Photography

http://cazillo.com/articles/37-photography/190-why-you-need-perfect-exposure-...

Underexposure is THE ENEMY of digital photographs! In this video I show you how underexposure can ruin a photo, losing color & adding tons of noise to a photograph. When you underexpose you dramatically lower the dynamic range of the captured image. Your camera might have 10 or 12 stops of dynamic range (which you paid a lot of money for) but if you don't expose properly you are wasting those capabilities.

I've noticed over the years many people are afraid of high ISO. I show you how exposing properly with high ISO can produce better results, check out the video!

I find in full manual, my meter jumps around. It is correctly exposed, then a second or so later, it isn't.

[GregoryCazillo]

@Maxsdiscos You are probably pointing it at something brigher/darker, that makes a difference!

Greg, I accept and appreciate what you have demonstrated and can see the reason for exposing to the right. It is really useful to see this type of educational video.

My only criticism is that you adjusted exposure using the ISO. It would have been a fairer comparison if you had used shutter speed to adjust the exposures between the two samples. That way we would not be comparing noise/grain in the images. Changing ISO can slightly effect sharpness and colour rendition too.

Still a great video.

@trevager That was my point, I wanted to show how underexposure can hurt a photograph and give it more noise vs a higher ISO.

@GregoryCazillo That's exactly what I got from this video. Great job explaining! I have a question, what kind of test can I do to see what is the highest iso I can shoot for an acceptable image?

[GregoryCazillo]

@unclestuntman That is all relative to personal taste, lighting conditions, lens quality, post processing, camera, etc. I shoot ISO 6400 and print 16x20 or bigger with my D3/D3s all the time. YMMV.

@M3mPHiS Do I look like a doctor?

[M3mPHiS]

Greg, I have a random question: what's a human eye's aperture number? :) thx

Good video

[rhidalgo987]

Agreed, Thanks!

[incamera2]

thanks

@Maxsdiscos or you're in single point metering. and its bouncing off shadows versus bright sunlight or w/e. if you change to evaluative metering. it shouldn't jump around so much

[MrRLPhoto]

Your the bomb. the most important exposure meter is the six inches behind the the camera. :D

@falecomcyber no, I only shoot in RAW i will do a vid on it when i get some time

[Wes2299]

@GregoryCazillo It's ok, I read up on it and when I import RAW photos into LR the photos become darker due to in-camera processing it does when I preview photos on my camera's LCD screen. Guess I gotta adjust my settings when I'm shooting.

I actually did a video on getting it right in camera. I OVER exposed an image instead and showed how important it is to get it right in camera. See, we all mess up sometimes LOL
