Re: Blue Splotches Showing Up In Video

Then that's great news. If that's what you were trying to tell me, then why were you focusing on me cropping in the image? I'm here for a solution no matter who gives it to me.

Re: Blue Splotches Showing Up In Video

Wish I knew more about video, but when I zoom in I see blue/green and red splotches.  It isn't limited to a fringe along hard edges like chromatic aberration (purple & green fringing) but that could nevertheless be part of the issue.  

 

It really looks more to me like color noise artifacts.

 

The small phone screen isn't helping me here. 

 

What ISO were you using?

Scott

Canon 6D, EF 70-200mm L f/2.8 IS mk2; EF 16-35 f/2.8 L mk. III; Sigma 35mm f/1.4 "Art" EF 100mm f/2.8L Macro; EF 85mm f/1.8; EF 1.4x extender mk. 3; EF 24-105 f/4 L; EF-S 17-55mm f/2.8 IS; 3x Phottix Mitros+ speedlites

Why do so many people say "fer-tographer"? Do they take "fertographs"?

I believe I was using 400 while filming this shot.

So I noticed this week that I'm getting blue splotches (and a lot of them) showing up in my footage, more specifically outside and in the brown colors (trees, fields, rocks, etc.) I'm shooting on a Rebel t5i. Here is an example. This video has it the worst and it even shows up some in the water. Any help would be appreciated. Thanks!


What where you cameras settings what ISO, Aperture, and shutter speed?

ISO: 400
Aperture: 3.5
Shutter Speed: I'm not entirely sure. Possibly anywhere from 200-600

At ISO 400 most likely it is not noise, but, chromatic aberration. 

 

What lens are you using?

Re: Blue Splotches Showing Up In Video

It's a stock lens that came with the camera. Canon EF-S 18-55mm.

Has the lens been dropped?

BTW, as a rule of thumb, you want the denominator of your shutter speed to be approximately double the number of frames per second that you are recording. In other words, if you are recording at 30 frames per second, you want your shutter speed to be 1/60th of a second.

No the lens has always been handled with care and placed in a bag after every use. Had it for 2 1/2 years.

And thanks! That's a good tip I wasn't aware of.
