Re: Gimp film-simulation resources
The problem is, apply it to what? Different digital cameras process their raw files distinctly,... I did some work along these lines, but it got bogged down. The idea was to photograph Makbeth chart, process the RAW using some standard settings then use Match Reference to figure out standard settin...

Re: Video editing advice
Million thanks! I have another ignorant question about the video formats - but just the big picture: what's the going standard format(s)? Here is what I would answer for photos. While there are many fine points for any of the following: 1) shoot RAW, but never send it to editors - process it and edi...

Video editing advice
Could anyone point me to some simple but sufficiently informative resources to explain the video editing technology (formats, quality, encoding, compression, codecs, editors requirements etc). Similarly, any portable software (freeware or not) that is worthwhile. If someone asked me a similar questi...

Infrared, digital cameras and purple fringes
While I was aware of digital cameras capturing light wavelengths outside of visible range, I haven't paid attention much. Below is a chance picture of a IR comm port of a laptop - invisible to a naked eye. It is rendered by the camera as bright magenta. I don't know what the wavelengths are, but pro...

Re: Flash Light Temperature
I removed EXIF:MakerNotes from a .CR2 file to see what will happen. It looks like PWP RAW defaults to 'no WB' when it can't read the WB data, but still reports 'Camera WB'.

JPG/PPW preview extracted from RAW
I understand that dcraw -e option can extract Jpegs/ppm: in-camera-processed preview images embedded in RAW. I find it useful in that I can only shoot and store RAW, always having access to the embedded Jpegs if needed (even if it's 1/4 size, that's still useful for web or previews, without having t...

Translating GIMP script to PWP workflow
This looks like a challenge that Den may like: what would be the simplest workflow that could consistently process images in this fashion? http://www.flickr.com/photos/28653536@N07/2879128071/#/photos/28653536@N07/2879128071/lightbox/ p.s. Would it be a good idea to start a depository of PWP workflo...

Re: Flash Light Temperature
There are channel multiplier values listed in EXIF/MakerNotes. Is that where dcraw reads them from to, then, derive Colour Temp and Tint values?

Re: Flash Light Temperature
When PWP RAW uses WB=Camera WB, where does it read the value(s) from? An EXIF/MakerNotes? I can't match the values of Colour Temp and Tint with anything that I can see in the EXIF.

Re: Flash Light Temperature
I noticed that as PWP RAW recalculates the preview, the Noise Reduction (if it's used) is applied twice: once for the WB and once afterward. Is that how it works? If it is, would it be possible and would it make sense to always apply the NR for the white balance (regardless if NR is actually used or...
