Hi everyone,

im very new about red camera, i just had the chance to shoot a short movie.

In a dark room... with some lights DYI

i woud like to know what is the best setting camera for that kind of shoot? ( shutter, Iso, Kevin...)

i joined a snapshot then you can get me better feedback

The actually setting was Shutter speed 172.8, Iso 250 , Kevin 3500, redlogfilm

Thank you

You didn't mention what lenses and aperture you shot this at. But generally speaking, you may need more light.

Red doesn't like underexposed, As Bob mentioned you may need more light... Fast glass and slower shutter will help you though

If you are shooting 24fps in a 50hz country you best you se 172.8 degree shutter as Patrick has done here.

If it looks to dark or uncontrasty in camera at 400 ISO in a scene like this, it probably is.

I read that as 1/170th shutter... My bad.. I should leave the advice to you pros :(

Yeah, that's likely way too underexposed; the minute you add contrast and/or try to get proper brightness you'll get some nasty noise in there.

At the very least, boost the ambient light level by a couple stops (via more light preferably, but even opening up the lens would be better). What is the left goal-post doing? What does this shot look like at ISO2000 (done in post)?

The exposure here looks fine. He says its ISO250. Which means he's got plenty of room if he wants to do any boosting in post, but it sounds like he wanted a dark room look anyway...

It doesn't really look like he's got plenty of room, unless he wants the image to be pretty dark. Lack of contrast is probably a bigger issue...

But an R3D would quickly disclose that.

Don't look blindly at ISO, as it isn't really too informative. Neither at 250 nor @ 12800 :)

Edit:
Phil is a source of good info.

Hi everyone,

im very new about red camera


Hi Patrick. I've found that many people new to shooting with digital cinema cameras like Dragon don't fully explore the in camera exposure tools and don't usually understand the concept of ISO rating. Here's some helpful things to get you started.

Thanks guys for all reply, thx Phil holland for the board i will study it. For my shot was using the 35mm Samyang lenses T-stop 2.2 .
i wanted my shot looking like dark room, here is the result after color correction and bring the iso up to 400 Iso. To me it looks good but maybe for you professionnal it might be wrong and lack of light. So should i bring the light higher? or should i be at 800 Iso and get bright light?

If it is already shot, then post an r3d file. If information is available, then guessing is not really needed, right?

An image looks good if it looks according to your intentions.

Hi Patrick, in Redcine-x, you can choose one frame snapshot for R3D file.
Go to the frame you like to send, and then choose R3D Snapshot http://i61.tinypic.com/34phvsy.png
After a few seconds, you'll find a one frame R3D file in your Desktop, upload that.

I once heard a respected lighting designer say "you have no idea how much light it takes to make a stage look dark". I think you will drive yourself crazying trying to get the look of a dark room from a room that's actually dark. You want to light it so it looks dark.

here is a quick pass on color. i think u have enough to work with. could have used some more lighting imo

Not that bad at all, I kinda dig the framing and the gritty look - especially when sampled down to HD.

Moving forward you may want try adding a stop more light, then do it again w/ 2 stops more light... the idea being to scale down later in redcine/post and see what works best for creating the look you want.

Here's a quick tweak I did in Redcine on an uncalibrated iMac display... I may hate myself for posting this when I look at it later, but BOOM here it is :thumbsup:
