HDRI render tests
I started to experiment with HDRI type of renderings.
Should produce some interesting renders i hope.
Not sure if its worth while or interesting enough to be a feature request.
Technical stuff below & some test renders.
High-dynamic-range imaging basics

Oversampled binary image sensor

Re: HDRI render tests
Nice! What would be the feature requests exactly?

Re: HDRI render tests
Still thinking on a cool name for it.Oscar J wrote:Nice! What would be the feature requests exactly?
Some automated setting for EV and ISO channels for saving out multiple images with multiple settings at once?
Or save out the HDRI type merged images? NOT Sure how or if it worth it.
But it can be useful to get a more wider spectrum in rendering...in therms of shadows & light.
These are just tests....you guys decide if its useful or not.

Re: HDRI render tests
Indigo already has HDRI output in .exr format (a more modern format than .hdr).

i know. But that will merge multiple expos in one?Oscar J wrote:Indigo already has HDRI output in .exr format (a more modern format than .hdr).
Its not the format its the result.
Preserve super darks and super whites whit no overflowing & more detail.

Re: HDRI render tests
Think of it like.... the data difference between a 8-bit|16-bit|32-bit TIFF format.

Re: HDRI render tests
Well, this is only a gimmick that allows a LDR machine such as a camera to portray an hdr one. Indigo doesn't need such gimmick as it already gives the full exposition gammut.Originalplan® wrote:i know.

High end RED cams have this option and high end HDRI lcd panels. Its a techological advencement...but if its needed...i dunno.

1 thing is certain you can eliminate the shadows in corners with this approach.

Re: HDRI render tests
Camera has a low gammut, so you take multiple shots so that you can interpolate the full gammut. Indigo make this calculation already, as these cameras you're talking about, it seems... there's not much to it. You might as well save the file in EXR and it will present you with all the available gammut this high cameras present you or you can select camera/reinhard mode and tweak it yourself. You can convert to HDR and import it on Picturenaut which is free or photoshop, heck! You can even take three different exposures, save them and create your own HDR!Originalplan® wrote:I don't think its a gimmick. But i don't know either if its needed...full exposition gammut or not.

The vignette has nothing to do with it and you can turn it off when exporting!Originalplan® wrote:1 thing is certain you can eliminate the shadows in corners with this approach.

Well how else would you do that?pixie wrote:You can even take three different exposures, save them and create your own HDR!
BTW PS has a great merge HDR feature inside so no need for plugins at all.

Not the vignette effect.

But if its pointless then it is..
I didn't said it will save the world.

Re: HDRI render tests
I think you might have had misunderstood the whole concept of HDRI's from Indigo. Indigo exports 32 bit HDRI images with a huge dynamic range, which allows almost endless post pro possibilities. These 32 bit images can be created with a normal camera by combining many exposures, but Indigo doesn't need that since it stores all necessary information internally to create a HDRI.
