  • 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 :)

Profile: SC 4.1 250ISO

Thanks all

FYI... I had my first EXTERIOR shoot on Friday with the SC.4.1 profile (credit to Miguel) with some pretty good results.

It was a cloudless, sunny, early winter day here in West Australia (love the light this time of year) and I was filming a series of roving vox pops with Aboriginal people. The only ND I had was a 6 which i used for most of the unshaded exterior shots.

I did stuff up the first few shots as I used the ND with both myself and the subjects under some shade. Im really paranoid about over exposure (bad habit from video) which is something I need to address with this camera as the shadow noise can be brutal.

The second half of the day we shot interviews under a patio. I ended up ditching the profile and used the default 320 ISO without a filter. Once again some really nice results using only available lighting EXCEPT I was riding the exposure as the clouds kicked in and flucutated the light. I wont do that again! If I had a colourist he would linch me but in my case its me so I will do the suffering in post.

A few days later I ran some tests outside without the profile. I feel at this early stage im better off running default profile until i learn and undertsand the parameters of the camera. I bascially kept it simple, used my light meter and recorded my fstops for each shot for reference. I also just used the raw histogram. I found myself setting about a stop under the light meter and achieved some good results.
 
Miguel, have you test your profile with the new Red B20 and color science?

just wondering because we have been using it on both exteriors and interiors and the DP seems pretty happy with the results. We're also using an 80C for interior tungsten scenes. We're still on build 17 for this shoot but I've been experimenting with the new Red Alert build. The DP seems to be getting more comfortable with working with this profile and the 80C filter.
 
I've completey fallen for Mac's profile - but thus far I havent been able to make it mesh with build 20. The colors seem overly warm and more importantly the curve seems to be completely different - when brought into RA the curve looks like simply a boost of the highlights.

This has got me for the mean time sticking to camera build 17 and just posting with ra build 20.

Any one have any thoughts on this? Do looks made with certain builds fail to load properly on new builds?
 
I have done shoot with macs profile and B20, no problem. We did a early morning shoot with low light. Used a MP 180mm, and a RP 18-85 and processed in RA 20 with very little noise.

Here are some frames.

Gorgeous grabs. Perhaps Im just unable to get it loading properly - You didnt have an issue with the 6000k setting looking very warm, even with daylight sources?
 
If the monitoring path and colour response has changed in build 20, how can Macgregor's color profile be accurate any more? I would imagine a new version needs to be made.

Macgregor?

Cheers,

Build 20 ...

Build 20 ...

The look profile file is [SC_41 250ISO.RLK] ... Build 20 seems to save them as [x.RPF] files ... eg : PROFILE_0.RPF.

Anybody got this profile working with Build 20 ? If so ... how ?

Thanks ...

EDIT : ops ... apologies was trying to 'load' profile from the wrong menu ;-( ... PROBLEM SOLVED
 
I´ve used the profile without problems on bulid 20.

Build 20 changes WB response and how colors are displayed. The SC profile introduces gamma curve changes, like a 1D LUT (mapping values into different zones) so they´re totally different things.
 
Wow Janne, that footage looks truly amazing. I would recommend to convert from video levels to Full range computer levels, since redcine and RA output in video levels (allthout you can clip and crush blakcs if you play with the settings).

Andrew, if 6000ºk are too warm for you just bring the WB down to whatever it looks appropiate for you. You´re not forced to stick with that color temp.

It seems to me, allthoug i haven´t tested this yet, that the new color science introduces the necesary changes in the RAW-RGB conversion to avoid the cold colors that we were getting before (something that i previously mentioned on this thread), therefore that problem might have been solved and you no longer need to compensate the WB as you raise ISO.
Again i haven´t tested this fact and i´m not really concerned since i always re-calibrate WB in post and i don´t pay too much attention to it while shooting.
 
i cant find the file sc41
where do i download it?

ty very much
