floating point reflection maps

#1

Hi guys,

feel a bit stupid asking this but I not had much experience creating hdr’s or floating point images.

If i’ve got a photo i took in raw mode on my slr, whats the easiest way to make that into a high dynamic range image? Can it just be imported and exported in photoshop?

I’m not talking about making a spherical map i just want the flat photo so it can be mapped onto a plane but have full dynamic range.

Thanks

As far as I know you won’t get enough dynamic range in a single RAW to make it high dynamic.
You will need to take multiple exposures and combine them with programs like HDRShop (and maybe PS even?).

Ah i see, is there any benefit to using raw images then if your going to combine different bracketed exposures?

Thanks dude

The last time I made any HDRI, I remember the program would take LDR images as inputs. So even if you had different exposures in RAW you might still have to convert them to 8bit jpg or tif first in order to create the final HDRI. I am not sure if that’s still the case today.

Cool thanks dude

Some software accept raw images, I think Photoshop and maybe PTGui.
The have more information in a RAW images than a LDR image.
There is a noticeable difference between the 2 when creating HDR images but in most case a bit overkill.
