Planning Ahead Pays Off
In this week's edit, I use an Edit My RAW submission to address skin tones. Balancing the needs of the image as a whole with our model's beauty, I use cropping and light to draw the eye to her eyes. I reference the Lab Color Chart to guide skin tones in light and shadow.
Treating the woman's image separately from the background, I find another use for compositing in the Watermark Module. I discuss prior planning throughout the image edit to make recombination a smooth and seamless process.
Getting more nuanced with compositing
In this week's edits I look at some trickier blends while compositing with the watermark module. I use a 15 second and a 1/4 second exposure of the supermoon rising and create an HDR image with parametric blending. I discuss some considerations involved in this composite in an attempt to show more nuance associated with the process.
The Edit My RAW this week is a shot from Thailand that was previously processed with beautiful results. I attempt to compliment the photographer's work with a few of my own touches.
Here is my latest version of my compositing script:
#!/bin/zsh ls -t .config/darktable/watermarks/tmp* |grep -v svg |head -n1 |read file inkscape -f "$file" -l '.config/darktable/watermarks/tmp.svg' ls -l '.config/darktable/watermarks/tmp.svg' |cut -d' ' -f5 |read size_n ls -lh '.config/darktable/watermarks/tmp.svg' |cut -d' ' -f5 |read size_h [ $size_n -gt 8000000 ] && echo "File too large. Size $size_h, but needs to be smaller than 8M." || echo "File size okay $size_h"
I set it up with a hotkey sequence and use it often now.
This Week Is All About Color
I've been working on a Lab Color Reference Chart, which you can download here. I looked through many thousands of images to find examples of common colors. After sampling and sanity checks on the data, I came up with these numbers as starting points for white balance and color correction in general.
These references are already quite valuable in my work; I hope they help you also. I put a copy of the png file in the directory I'm working in, to give me quick reference to the chart while working in Darktable.
The RAW file used in this video is available here. Thank you Andreas for the contribution 🙂
I also calibrated my monitor for both web and print profiles. After a bunch of bumping around in the dark, I came up with a simple solution here:
#!/bin/zsh dispwin -c dispcal -v -m -H -y l -q l -t 6500 -b 80 -g 2.2 web targen -v -d 3 -G -f 128 web dispread -v -N -H -y l -k web.cal web colprof -v -D "web" -C "Harry Durgin Photography" -q m -a G -n c web dispwin -c dispcal -v -m -H -y l -q l -t 5500 -b 80 -g 2.2 print targen -v -d 3 -G -f 128 print dispread -v -N -H -y l -k print.cal print colprof -v -D "print" -C "Harry Durgin Photography" -q m -a G -n c print
I switch between them with a hot key sequence. For web I use
dispwin -I web.icc
and for print
dispwin -I print.icc
I hope it works for you too.
In this video I demonstrate the functioning of the parametric mask sliders in Darktable, use my new compositing functionality on a contributed RAW file, and introduce my Lab color reference chart.
Along the way, there are quick tips on Inkscape and on adjusting panel width and font size in Darktable. I use compositing in Darktable like an old hand now, but here's a quick reminder from last week: Keep your SVG file under 8mb; use Inkscape to convert it from a bitmap like this:
inkscape -f filename.jpg -l filename.svg
and put your SVG file here
