Custom Image settings and RAW.

Do camera Custom Image settings affect the RAW image? Searched here and the latest thread I could find about this is from 2015. And dealt mostly with Silky Pix. Some answered Custom Image settings only affected jpeg images. Others said the changes in RAW would be saved if using Silky Pix. One answer said "some" Raw conversion software would save Custom Image changes. Searched the web too and could not find a definitive yes or no answer. Is there a simple answer to this question? Any help would be greatly appreciated.

Some, if not most raw converters “read” the custom settings and use that as a starting point for development. From my understanding (which could be wrong) the custom settings are for jpg and the jpg thumbnail preview which gets embedded with the raw file. Silky pix and I believe Adobe products will use the settings as a starting point. Rawtherapee does also, which can be turned off to render the raw image without the presets. I’m not sure on other software.

Hope this helps.

I have always thought that Pentax Digital Camera Utility (PDCU) was the only RAW converter that could read the Pentax custom settings and apply them ...... I believed that all other software was unable to act on them.


As I have understood it, the Custom Settings when shooting RAW, will only have an affect on the JPEG preview on the camera screen, and the Embedded JPEG (as Tony explained) which would show up in the Thumbnail Displays of software like Lightroom. But in terms of actual processed output from Third Party software then don't think there would be any effect from a RAW file conversion. The software would apply its own default (or user customised) profile for the RAW type as the starting point.

Thanks. I appreciate your help. Also dawned on me I could take a shot with the default settings and one with custom settings drastically changed and compare in my RAW converter. Duh. Again, I appreciate your quick reply.

Thanks for your input as well mcgregni. Rain has finally stopped after three days so I think I'll go outside and do some test shots.

Yes, please try it, and tell us what software you used. It would be great if you shoot in RAW+, to see the original JPEGs from the camera (with the 'drastic' differences) and then a default conversion (with no adjustments) from the RAW file for both of the shots. That would be a very informative exercise and benefit many people here.

The settings are written down in the raw file's metadata, but otherwise have no effect on the file itself. Depending on you raw converter, they may (if using your camera or PDCU) or may not (most other software) be applied during the development process.

The best way to check is to set the camera to take a black and white shot.

Geez Dave. Sounds so simple when you put it THAT way. And that's just what I'm going to do. From one Dave to another. Thank you.
