Skin tone test

[Samana76]

Hello everyone,

I'm getting ready to do a shoot in about a week and have been trying to practice color correcting footage to create rich and natural skin tones. Here are a few screenshots of what I have come up with so far. I must say I am very pleased with the results but I would truly appreciate the comments and suggestions of the community here as I respect your opinions. If you have a critique please let me know how you would have done it differently so that I may test your suggestion and see if it works better. Thank you.

Here are the links to download the 1080p screenshots for a better view:

very nice skintones!

 

[skatajkid]

yeah, looks amazing! Scratch and ACES? Also interested in what lenses you use!

 

[Samana76]

Thanks guys for your comments. Skatajkid I used a Carl Zeiss Jena Biometar 120mm F2.8 MC lens on all the shots. It actually becomes a 180mm on a S35 sized sensor. It is a beautiful lens with great bokeh and is actually sharp from 2.8 becoming extremely sharp by f4. I used scratch, but not ACES. I used an X-Rite Color Checker chart and created a LUT in Resolve using the fabulous color checker function. I then slightly edited the LUT in Lattice and finally brought it in Scratch where I just lowered the gain ever so slightly to get the highlights back.

There was a third comment here yesterday which I glanced quickly at since I was at work. It was interesting as the commentator wrote something about seeing some green in the mid-tones of the skin. When I arrived home to read it more carefully it was gone. Can anyone recall exactly who it was and/or what the writer wrote?

Cheers,
Igor

I hate to be picky but a 120mm is still a 120mm, no matter what you put it on

Those Jena lenses are very nice though. The skin tones all look pretty decent to me, the close-up of the lady looks a little yellow to me, although I think that is probably the light she is in, it looks quite evening-y.

Wouldn't a medium format lens like the 120mm Carl Zeiss Jena Biometar have a crop factor and be a different focal length on a Super 35 sized sensor?

 

[JMtheDP]

No. A focal length remains the same, whatever you put it on. Now it is accurate to say that a 180mm lens on a full frame DSLR will have the same ANGLE OF VIEW as a 120mm lens on a S35 camera, but they are still two focal lengths.

Imager sizes change, which impact the angle of view. But they do not change focal length.

It gets complicated if you're using a speedbooster, because that changes the size of the projected image, but if you're using a simple physical adapter - that is how it works.

Exactly!

Thanks James for that explanation. Of course you are absolutely right and it is very clear by thinking about it. I hastily wrote that a 120mm FF lens on on S35 is like a 180mm lens, but in fact the correct wording is the angle of view is similar to a 180mm on a full frame sensor.

The young man was shot earlier in the day, around 5PM. The lady was shot later around 7PM, so the sun was lower and had a stronger golden tint. I am quite happy with them although not 100% - I still need to improve. I must say that I really do like the many gradations in skin color captured by this camera. There are so many subtle colors in the blemishes of the skin, the tiny blood vessels, the cartilage of the ear, etc. Unfortunately these variations are not so evident in the compressed images above.

Well thank you all again for your comments.

There is a lot of misinformation about that online. You are off course correct. A 120mm lens will always be a 120mm lens no matter what. Even because it's physically impossible for the focal length to change because we are talking about a focal length. It's a bit of a pet peeve of mine when I read people saying a focal length becomes something in another camera. I think this whole misinformation probably comes from the same place that teaches people to call a S35 sensor a "crop sensor".

 

[JMtheDP]

I think the whole misinformation on that stemmed from the DSLR world. People are always going to equate stuff to what they know. All the vocabulary about "crop" sensor, etc... comes from DSLR stuff. I guess a lot of shooter come from DSLRs these days, or at least have experience with them.

I get most frustrated now when I see some cameras (esp. cheaper ones) only have their focal length as "35mm equivalent".... 35 what? Full frame, APS-H, APS-C, academy !?

 

[Aaveum]

Yes I would have to agree with you James.
