  • 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

'Never a rose without the prick' 3

'Never a rose without the prick' 3

Finally we've got it:

"Our favorite RED1 footage" that obviously is not affected with some of you guys beloved (virus) profile.

Game Over

The End

My experience shows me that rating the camera as 250ISO (not to confuse with setting the red one to 250iso) allows you to get the best possible image in 95% of situations. But always have an eye on your RAW parade.

So now I'm a little confused- should the ISO of the camera NOT be set to 250, and then the camera also be rated at an ISO of 250? According to the earilier posts, I thought that the camera was supposed to be set to ISO 250 ...
macgregor said:
... - Your ISO setting in camera should be very close to the ISO in a lightmeter (250ISO in camera, 250ISO in your lightmeter) ...

So, once you load the profile all you have to do is set your camera to 250ISO.

Lastly- Can someone clearly explain to me the rainbow meter on the LCD? I get that it is supposed to be a meter for the RAW image, but what do the colors mean exactly?

RED ONE 320ISO with rec709: real life 125-160ISO
RED ONE 250ISO with rec709: real life 80-100ISO

Ok, I get that- that fits with my own experience...

macgregor said:
RED ONE with SC 4.1 250ISO profile: real life 250ISO

So does that mean- RED ONE 250ISO with SC 4.1 250ISO profile: real life 250ISO?

That is what I understood from the first posts, but then the later posts do make it as clear ...
 
so basically you just underexpose 1stop in high contrast scenes to get the highlights in rec709, right?

wouldnt that mean that you feed the blue channel less than optimal and thus creating a little noise when going to redlog?

edit: just trying to understand :)-no rant
 
macgregor said:
Nope, same shutter but different apperture, since with default 320ISO you get a real world 125-160ISO, while with the SC 4.1 preset, you are getting a real 250ISO, so it´s more sensitive to light, therefore, you´ll be closing your lense about 1 stop.

without SC,
real world iso of 160 asa when looking in redspace or redraw?

in my experience when looking in raw the lightmeter seems to be right....in redpsace there is a one stop difference
 
I did a quick test of the profile, and I think it was very useful and very good work by macgregor.

:thumbsup: you're fully right.. you can always avoid a stupid smile as avatar as you wish.. does it work w/ the PMs too?.. :blush5:

but then anyone can somehow bash you and you will not even take notice..

clever tip.. seems the same strategy of those incredible posts ki$$ing the usual asses announcing a timeline ridiculously unlikely.. but someone is keep going w/ the most pathetic fantasy trying to convince himself (worst.. thinking to convince all the others too) of a somehow useful way to kill the useless time.. do not dare to answer this one here now.. you won't take notice anyway..

:iamwithstupid: stupid smile avatar apart

albert is right.. your true contributions along reduser history don't worth it.

take it for free as a sincere advice.

edit
nice idea for a thread anyway

View RAW seems to be just like if you set the camera to 250ISO, camera RGB, 5000ºK and any other value set to default. That´s why if you use false colour with this view (which you shouldn´t use btw) will give you a real world ISO of something like 100.
 
macgregor said:
Now another problem for the old school DPs that want to use lightmeters when shooting digital, is that the readings from their lightmeter set at 320ISO do not match the false colour and readings when exposing with the RED ONE at 320ISO setting. Usually the difference is about 1 stop and 1/3 in 709 mode and 1 stop in RedSpace. This sets the real world sensitivity of the default RED ONE about 160ISO. Not good.

This thread is really interesting...

now can you explain me why the readings of their lightmeter set to 320 do not match the red histogramm readings with the red at 320 asa?

the why is the important part for me.

Hi Macgregor,

Just to make sure that i have the right curve, this is the right s-curve of your look ?

Thanks so much for this look btw...
Click to expand...

Yes, those values seem to be correct. (19.22, 34.57, 75.88).

Also have in mind that the RED LCD, RED HDsdi and QTproxies work in limited range, while redcine and redalert seem to show the footage in full range. Just so you don´t get crazy about colour spaces.
 
macgregor said:
Ask RED not me. I didn´t design the camera. ;D That´s why i took some time to develop the profile curve, to fix this problem (among solving the other issues discussed in the thread).

i dscovered that lowering just the exposure -0.4 and in the RED solves that Problem too.

btwl
i cant exactly remeber but graeme or stuart wer talking about something with -0.4 exposure


@Cristina:
so why do you post another useless sentence in this thread :)
