  • 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 :)

9 1/2 stops...

Not being a smartass here...but there's even more stuff there. Taken from the first dark example JPEG. With the 4K RAW/tiff route results could be even better. Also NOT meant to be usable.
Sorry Jim for fiddling with your pic.

Wow.

Amen omen! :)

How much do you charge per hour?

Maybe I should delete that 2nd one? It is not a useable grade. It is just hyper-extended to show the info is there. Or were you kidding?

Don't delete the second image, I (others) understand the point of what you're showing.

T32 -1.7
To pull out anything like that is to my calculations 9 stops under exposed and hold that much detail while the background stays almost the same. Damn. I have been to hundreds of telecine sessions and that would be a good grade in anyones book. Obviously this is showing a more docu situation but if you have some fill you are golden. This blows my socks off. I have seen Jim grade images before and I don't think most people understand what he knows... Curves. To anyone who thinks that the second image should be deleted I wonder how many times you forgot your light meter and needed to have a colorists save your .... project. If this was a docu and not a larger project with more money for fill etc. I would be really pleased.

Extremely well put. As a matter of fact, all the griping and such makes me wonder how many people on this board actually shoot. This is a no-brainer guys.
 
You can take it really far in a few minutes if you're wiling to use a garbage matte and venture into uncanny valley. It just starts get pretty splotchy pretty quick. :D

I guess it frustrates me a bit when people say we have 6-8 stops of latitude. But RED is a different animal. If you know a few secrets, the image is incredibly elastic. It is not film. It is RED. RAW is your friend.

Here is a frame from a short I shot and am beginning post on...
BrumbyHDR.jpg

The top frame here is properly graded, the bottom pic is what I saw when opening the R3D. I exposed this scene at ISO 500 knowing that those building in the background were 4+ stops hot and I wanted the chance to recover them. Experience told me I could do that and still light for the face at ISO 500. All I had was two 1200W HMI's bounced into foam core and a 200W Joker for an eye light. There is some noise in the lowest tones but it's not distracting at all once they are dropped into their proper range. I think this shot is gorgeous! and I can't wait for B16 so I can push it even farther.

Yes sir, now you're talking. Excellent work. So what's your day rate? :biggrin:
 
Jannard said:
Great example Evin... we are finding that way too many graders would NOT have recovered the detail in the building.

Well, Evin sounds like he truly understands how to expose an image for a given lighting condition. That first step makes it a tad easier to manage a scene such as this in post. If your background is super hot, and you know you don't have a way to physically knock it down on set...your other option is to reduce the contrast ratio between the subject and BG - which is what he did. He brought the subject up to a reasonable point, so a proper grade could be accomplished later.

As simple, and as difficult as that.

I've been pushing the limits of curves and DR on DSLRs sine the Kodak DSC760c which I shot product photography with in 1998 right out of Brooks.

Ahhh, so you went to Brooks. No wonder.

Don't let it frustrate you...it seems to me people just need to USE the camera, read a few books on proper exposure technique, or as many have suggested - play with a DSLR, and then grade the images in Photoshop. That ability in and of itself is revolutionary. Jim has tried to make a professional grade camera accessible to the mainstream, by basing the fundamentals on techniques available to most of the population.

In school, I remember exposing Super 8 reversal and being frustrated with the results at first. Now, I understand why those lessons were so important. Talk about no latitude. If you can get that right, you can shoot damn near anything and get usable exposures.
 
The great thing about RAW is that if something went wrong, it's pretty easy to figure out if it was user error or faulty data. No need to call a post house and ask them to see if they can't stretch it further you can just check yourself.
 
With all the talk about getting the exposure right, what was the exposure?
Reference T1.7 - 32. Are the highlights +2? +3?

Just shot a test yesterday, found 10.5 stops of latitude.

thanks,

Yep,

There will always be some people to say that sort of things.

This camera is a monster, it's strong, it can save you and do wonders, but without proper care or basic knowledge, it can bite you.

This is a purely MANUAL camera, in the best possible way. Love it!!!!

Now please bring that @#@# beta build 16. :)

Cheers.

In RedAlert, altering ISO is the same as altering exposure.

Graeme, you lost me here. Evin - "I exposed at ISO 500 (Camera setting), chose consecutively lower ISO's in RA until the right side of the histogram pulled behind the wall, then used the exposure slider to fine tune the highest value to what looked right"

Exposure slider for fine tuning?

Lim
 
Yes, it's for fine tuning.

Now do some creative secondary color correction and you get extra stop.
It is what I see but it is by measuring absolute pixel values that may not be always related to the visual perception.

I have to do the film versus RED test, but when I will do it I will screw up the film test big time, since not much up to date experience here:-)

If David will make one together with Jim, I will know that they got the best of both.
 
Just a thought.

If one wants grain in his final picture, he could just play with ISO and processing and achieve a pleasant level of noise [+ (possibly) extra DR].

Without the need for additional grain, later in post.

Not much control, though. Of the noise structure, etc.
