Conversion Artifiacts

deeky · Mar 9, 2014

Forgive me if this is the wrong place.

I've been running through Lightroom for initial RAW conversion, and then using "Photo - Edit In...", I move it over to Elements 11. Everything has worked fine until tonight. two different photos (only ones I tried) gave me issues. You can see in the photo below where I circled it in red. It seems to be happening when I am converting from 64-bit depth, since Elements 11 doesn't support that depth. I've done it the same way in the past and had no issues. The only difference I can come up with is that I was using a cpl on these photos. It's a decent one I think - Hoya #62.

Any help?

That could be from light hitting the CPL, is the other image shot from the same angle with the light hitting it the same? I would worry more if it had been an ongoing problem, but since it's not (at least yet) it most likely is flare or something from the filter that you got in these two images. Is it a known better quality filter?

i wonder it would be flare from the filter or something like that,
anyone might have a better conclusion of this?

If it happens on different photos, but stays in the same area of the photos, my guess would have more to do with the sensor.....maybe some oil, or something on it. I am reaching on this, but I can't see the other pictures to see if this is true or not. Maybe post another shot.

The photo is no longer available at Flickr.
It could be posterization.

Elements is pretty much limited to an 8-bit color depth.

How do you come up with 64-bit depth?
The max bit depth in Photoshop CS/CC is 32-bits and that is for HDR work.
ACR (Camera Raw/Lightroom) can only do 16-bit unless a photo is first set to 32-bits in CS/CC and then imported into ACR.
John Nack on Adobe : Creating 32-bit (HDR) images in Lightroom 4.1

Personal computers today handle OS code in 64-nit chunks but that is not the same as color bit depth.
So there are 32-bit and 64-bit versions of Adobe software but that is not about the color depth.

DSLR cameras make Raw files in a 12-bit or 14-bit color depth. Raw converters make those files 16-bit files but the color depth of the files is really still 12-bits or 14-bits.
