FS7: blotchy footage

Where in the menu would you go to see if the "master gain adjustment" level? thanks!

I rarely jump in on the exposure conversations anymore since I now know how to nail it every time. It started with a ride back from Boston with my friend Doug Jensen years ago. Remember Doug? Doug was too the point in the conversation which I always appreciate. Doug told me as he has here, how easy it really is, just trust your zebras. Learn the right zebra setting and use it. Done!

Hi Paul, of course I remember that trip but it seems like a hundred years ago! Time sure flies.

I must admit that zebras were absolutely of no help tonight with the FS7!



But zebras sure worked earlier in the day.

I have two methods on getting correct exposure with the SLOG3. By eye using the REC709 Mlut, not a pretty thing to look at but if you have some experience with traditional videocameras you can clearly see just by looking at the image if you are blowing out any face or other parts of the image, of course a lot will LOOK overexposed but that's when you use the high/low button to check the highlights and lows.

Second method is the one I use 90% of the time: I look at the bare SLOG3 image, then I open up until I hit the highlight warning, and from there start closing the iris while looking at the WFM. I'm aiming for a fat line in the middle of the WFM, and often that will be just a bit under the highlight warning. It works great most of the time, but sure if you're shooting an interview where the subject is in front of a bright white background, you have to accept that the most of the WFM will be over the middle but you will clearly see the subject being under on the WFM.

Ah, so that rocket finally launched, cool. I missed it by a week.

I can see why the first one Zebras did not work, but the second I would use nothing but Zebras and never a LUT or by eye.

My eyes are never consistent. They are affected by adjacent colors and gradients.

Like this one:

For example, in the image below, you will probably find it hard to believe that squares A and B are actually the same shade of gray. However, if you screen cap or save this image and open it in your image editor, "select" square A and then pull it next to square B, you will see that they are in fact the exact same color! Almost impossible to perceive at first glance though.

Zebras would spot the illusion right away. My eyes are fooled time and time again

I just want to take time out to thank Doug for the extensive input he provides to this forum.

Thank you for the nice comment, but I am just one of many people here with good information to share.

Indeed.

Another one, no movement at all, until you stare at it.
