  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

DR ..a good discussion!!

David,


I see what you mean. For the first one, I thought it was simply just the shadow from the blinds blades, but it didn't appear to be that. And on the black gentlemen's face in the backseat, I thought it was just my grade or the way his skin tone was being captured by the camera. If can help you any further with your test just let me know with a PM on this or in another thread, I'm nowhere near the smartest on this forum but I will do whatever I can.


Rand
 
David,

The last of the three images you posted.

I promise! no more than one possible "Redo" in the future. But be sure to remind me. I know people must get tired of me reposting shit all the time. Sometimes overnight, I think of a new way to grade what I already posted and just wanted to resubmit it. However, In the future I promise to wait for my third idea on how to grade something and then post "that" one. Okay, Deal?

I think your posts are great Rand. They are inspiring and fun.

And on the kid in the backseat, did you mean his "actual" right or "Camera Right"?

Hey, Rand,

wasn't that guy's hoodie supposed to look more, like, grayish than blueish? And why is there a reddish halo on that guy's green shirt?

This is what I get:

If not pushed too far, (chroma) noise is acceptable and smear isn't that visible.
And let's not forget that this is 6K @ 9:1 REDcode.

No coloring work, just exposure, contrast and custom RWG/Log3G10 to sRGB conversion. Think this is not bad at all... :smile5:
 
Its probably from me trying to get the gentleman in tbe backseat skin warmer and less blue or green and the seats more tan. In the guy with the woman in the car, his skin was easy to get but hers stayed more green so I tried to fix hers with out affecting his so much. Its more a mistake on my part for being aggressive with the grade. Don't really know what color his hood was supposed to be though.

Can't spot the smear though. Do you see it?

You're right, David knows that. :smile5:
 
Sabovic,


I think I got it right where that circle is, but again, that may be a grading error. I think you're more right about the color of the hood than I was though.
 
Sabovic,


Ha.Ha.Ha. David said that the scene with the outdoor light coming in to the dark room showed it. This was what I saw. I thought it was the shadow of the blades of the blinds but I don't think so.

Yep, clearly visible. It also is quite a bit noisier than what you usually get from Helim with Standard OLPF. :ack2:
I'm guessing it's that "blackshade" thing. Has to be. :smile5:
 
Sabovic,

Here are two quick re-grades approximations of two of the images in Redcine-X Pro along with .RMDs. I was just "Eyeballing" the guys skin tone without a vectorscope so take the skin tone with a "Grain Of Salt". Shouldn't be any or little chroma noise in the backseat guy scene now. So that you can see what I did right and what I did wrong.


Here are the links to the footage David provided.

This is what makes the noise pop. I think it's better to go with a toe than crush blacks. :smile5:



The other image, yeah, I see Tint around -9 there...if you WB it off of the pages of that book he's holding, you get better colors. :yesnod:
I'm getting 6145 Kelvin; -8.514 Tint. Then contrast => done! :smile5:
 
Sabovic,


Yeah, one of the consequences of me trying to "Open Up" the shadows was noise. The non-graded image didn't appear to have much "information" in the shadows so I just slammed the blacks like a Latino Lowrider. I usually try to use the typical "S-Curve" for "luminance". I am trying to "Wean" myself off of always trying to find a white point in the image and just trying to do it by using "Scopes" and using "Kelvin" , "Tint", "RGB Curves" and "CDL". However, doing that might not yield the best results as apposed to a simple white reference in the image.

Also, another little tip, if you can't find something "White" in your image to white balance from, find something "Black" and it usually gives you a similar result but sometimes its worse, just all depends.
 
Here's an unscientific Helium smear test. I'm not posting a photo because you really gotta see it in motion.

First with a smaller light ratio than the second. Both are ISO 800, 5600K -5 tint, Standard OLPF, IPP2 Low Contrast Medium Rolloff - Just manual black shaded right before this test.

Unless GIO scope and the stoplights were lying to me, the white in the phone screen was NOT clipping.
 
Aaron,

It appears not. Funny how the overall brightness changed when the only thing you did was change the lighting ratio but with the same "brightness" level in the phone.
