WB Presets- Flash is 6518 K, not 5600K, why?
My Flash preset is 6518 in the WB Tool menu, my understanding is Flash is either 5500 or 5600; if so then why does my preset set to 6518? Can this be changed?

In general, in raw converters or raw processors, the white balance Kelvin values are merely an indicator or approximate. There is no reference. Don't bother (if possible). 0 -
Hello Paul-
Thanks for you response. I would like to discuss this more; not having the vast knowledge of the program as you do and probably as deep an understanding in photography either, I tread lightly here. The purpose of the presets is to give you a starting point based on an generally agreed upon value, from my understanding. From what I have read, 5500/5600 is the color temp. of flash which is set by the manufacturers to match mid-day sunlight. 6500 K is more a cloudy WB value, so for C1 to use 6518 is to cool of a temperature. Thoughts?0 -
To echo Paul's reply...the K value is just a reference, much like the "film counter" on a digital camera. It's only approximate and in fact Kelvin temps are not exact anyway. They certainly will not match to any standard across software/hardware to any degree of accuracy...
RAW converters ARE accurate AFA white/grey values, and in the case of COne's profiled workflow, you can use a WYSIWYG approach with a good calibrated monitor if strict WB is not the goal (warm lighting at sunrise/sunset for example.) I think ignoring the actual K numbers presented is really good advice wether COne, DPP, or other software...0 -
Hello John,
Thanks for hopping in here. I have to respectfully disagree... 😊
Here are the presets w/in C1:
Warm White F: 3142
White F: 3162
Sodium Vapor: 2801
Incandescent: 3003
Cool White F: 3756
Day White F: 4853
Sunny: 5204
Cloudy: 5972
High Temp Mercury: 6277
Flash: 6518
Daylight F: 6578
Shade: 7985
Strobes from what I have studied are built to match Bright Day Sunlight, which is C1's preset of 5204 K. This being a generally accepted standard then the "Flash" preset would be better at a lower temp value, 5500/5600 as the default setting. When I process I know what type of lighting I want to match and want the preset to be closer to that range rather than further, e.g. 6518 which is a higher temp than the "Sunny" preset value. The current "Flash" setting is higher than the "Cloudy" Setting which is a setting a lot of photogs will use to "warm" photos when using "Flash". This goes directly against intuition.
Cheers,

I'm not sure what you're disagreeing with, this is a workflow issue. IMHO, the most efficient way to shoot/adjust files is to shoot with a consistent "as shot" setting (I use 5200K consistently) other than AWB. As long as all the raws in a given lighting situation are similar, you can then adjust one and apply to all.
You can choose to WB, use a preset, or just eyeball and adjust one file. In my case, since my studio strobes are best at 5200 K, many files go as shot...however, it would not be "wrong" to use, say..the cloudy daylight preset on those shots even if they were not taken in cloudy daylight. I don't use the flash preset much, I find it is a little cool for my taste when I tried it. Color is very subjective, my goal is to present warm and true skintones. If your files look great at 5500K, simply use that setting and apply. I find fellow photographers like the cooler look of files, so they are very happy with the flash preset for their work. It does render wedding photos to a very neutral WB...so there's absolutely nothing wrong...and if it doesn't fit your vision, use a preset that does (or if you want absolutely neutral files...use an Expodisk or grey card and click balance.)0
