32 Bit HDR in Photoshop

Gav HDRHDR, love it or hate it there’s no getting away from the fact that sometimes your camera can’t capture all the tones in a high contrast scene that you see. At that point you’ll need to take more than one image and blend the exposures together and create a more realistic (or surrealistic) image.

HDR is hugely popular too. Just look at all great ways that are already out there to make an HDR image. Software from the likes of Nik and Photomatix are popular choices. Camera’s like the Canon 5D Mark iii can process an HDR sequence without the aid of a computer. So why would you want to learn another method? Well this isn’t 16 bit HDR… this is 32 bit HDR and trust me, size matters!

Currently only on Adobe Labs, Camera RAW 7.1 Beta allows you to import and edit a 32 bit Tiff file and although the technique for making a 32 bit file is a little fiddly the results are truly stunning.

    That. Is. A-may-zing!

    Cheers guys.

  2. surely if the photo is 16 bit you cannot upscale it to 32bit?

    you cannot add data which was not there in the first place.

  3. Robert. Your theory is correct, if one photo contains 16 bits of data you can’t create more original data. However by combining multiple images you add their individual data together… The more images you combine the higher the bit depth you achieve.

  4. Gavin, your the man, thank you.

    Hi Gavin

    I have CS6 for Mac so I have Camera RAW 7.1

    I have clicked on your link to open Adobe Labs but I can’t find Adobe RAW 7.1 Beta?

    Has it disappeared or is it under a different name?

    Thank you
