RED ALERT and Sharpening.

[Cal Brunker]

Assuming you guys want to do some post sharpening, how are you doing it? (software etc.) (I'm not missing something in REDCINE or REDALERT am I?)

Also, what is Leading Lady? Can someone explain Debayer detail? DRX ?

Is there a RED ALERT tutorial posted anywhere?

One other question ('cause I don't want to start another thread for it) how do you get the histogram up in REDCINE? Are there quality differences in the renders from REDCINE vs. REDALERT? Why two different programs?

Thanks so much!

Cal

I just noticed that in red alert "olpf compensation" to "high" will make the image very "muddy". My 2k images looked much bader than old HD Sony 730 images. Once I turned "olpf compansation" off, the resolution glory of RED was back again I find that the "sharpening" effect you get with the "olpf compensation" set to "high" not to be that great.

I think you will want "debayer detail" on "high" to get the most resolution.

Again, not to seem ungrateful...but I have been asking for manuals for long time.

The REDCINE tutorials only "scratch" the surface.

REDALERT...can't find anything...

I'd love a comprehensive explanation of these things too.

DRX controls image highlights, rolling off all colours to white if one channel is clipped prematurely

Debayer detail adjust the debayer algorithm depending on what's appropriate for the subject matter. From what I understand, higher settings favour detail; lower settings (Leading Lady) favour smooth gradations.

OLPF compensation is post-sharpening to compensate for the low-pass filter in front of the sensor. You can leave this off and use another sharpening tool if you like.

Hit 'u' in RedCine to bring up the histogram.

I have used the Sharpen filter in FCS a few times.

"U" in REDCINE brings up Histogram while "H" brings up the other key commands.

I find that you get the best results to export without sharpening, and then apply sharpening in FCS if required. The image crop (300% from 2k image) on the left is FCS sharpening and the one on the right is RED alert at "OLPF compensation at high"

Here with more sharpening in FCS. The image crop (200% from 2k image) on the right is FCS sharpening and the one on the left is RED alert at "OLPF compensation at high"

Another great tool is unsharp masking, which you'll find in most compositing software.
