  • 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 :)

HDRx Overview...

Got that... :-)

One thing I wonder, though (directly in connection with your statements), is

Do you have to adjust it in whole stops?

Let's say I want the A track @ 1/48 and the X track only at 1/72 (half a stop over) just to get the little additional headroom in the sky I need.

Ah...

Bottomline is:
Cannot wait to play with it and test it a bit systematically out...

I really hope you will be able to shoot some more HDRx very soon Mark!
 
Driving around today, a hot summer's day in Melbourne and I can see HDRx opportunities everywhere. Anyone who's ever seen Australian light will know what I mean. First time I shot in the US it took me days to get used to how flat the light is. Over here it's really contrasty.

The pictures we posted earlier were made with our standard DI system. No new software. We literally just loaded 2 dpx sequences (rendered out of RCX), stacked them on top of each other, and started keying/masking/coloring them.

I believe RED is also developing tools in the SDK to make this process more automated and hassle-free. (a la the slider)

I am assuming that blending the streams in the SDK will save most workflows some storage and render time as well.

Ian, as Jim suggested and you have verified, there are going to be many ways to skin this cat.

That's good because professionals like you will surely be able to use it in ways where footage can be made to jump through hoops.

I really hope the slider approach RED is adopting becomes common across all apps, at least as one option. Being someone who prefers a ballpark visual approach to that of an exact numerical one, I really would like to get that same "feel" when working with HDRx™ footage no matter which app I'm using.

Let's not forget that we can still incorporate grad filters to really start to play with looks.

My guess is that the secondary stream is increased that the motion math will have a unique look. It will be cool to do some "power windows" in camera with traditional filters and then see what kind of unique new cinema we can produce with that.

I wonder what the IR differences will be. If you shoot ISO 800 outdoors with filters and HDRx.

Dang it. I just realized that I am a Testoholic. :)

HDRx™ Check

HDRx™ Check

Mark L. Pederson said:
What would be super awesome is if RED could add a "HDRx™™ Check" button in the menu - this would have Off, +1, +2, etc.

All this would do is adjust the shutter setting - altering the monitor path so you could see (in an RGB representation) how much of your highlights are clipping and/or can be restored at the specific HDRx™™ setting (+2, +3, etc.)

This way, for example, you could expose for the darkest part of the image that you want to hold detail, click on the HDRx™™™ Check in the menu and look at the monitor path and find your HDRx™™ setting - as I think the name of the game, unless you are going for Magic Motion specifically as an effect, is to use the lowest amount of HDRx™™ to get what you want.

You can obviously do this "manually" - changing the shutter and then changing it back - if you are good with math and can think fast - but I thin it would be wicked cool to have in the menu -

DEFINITELY Second this idea. I would program it to a user button and make it part of my RAW Check/Exposure Check rhythm before shooting.
 
Well there you go...Mark has used in the field and made a wicked observation. Definitely seems like that would be a great feature if it could be done (i.e. HDRx Check).

But sure, you can just open up a bit, exposing a bit more to the right, and "pick" (guess) an HDRx™™™ setting like ... +4 and go. -

A new kind of histogram could be usefull: Showing you how many stops are beyond the right border.

Just thinkin' out loud ....

Also racking the iris a couple of stops would work for a quick look see too, especially for Dp operators, I would imagine that that would be the way I would evaluate how much HDR to use in the first place since I rarely use a meter.

Does HDR work in stills mode, if so what is the upper limit of shutter speeds?

Yes... limits are the same as motion.

2.5:1 is somewhere around 14-18fps to an SSD. That will grow as SSDs get faster.

And, of course, I will need to overcome other important limitations, such as my own imagination...nice one :beer:
