Well, processing photos is quite new to me, so I'll record some of my
experiences as I go along here.
Idea was to expose for the highlights, then boost the shadows in
another layer. The use a mask to show the appropriate bits where they
are needed. Alas the camera ISO was accidentally set to 800. This
resulted in the boosted shadow bit being very very noisy, with
horrible splotches in the red channel.
Do two conversions, one for highlights, one for shadows.
Shadows, noise processing
- Copy to new layer
- Blur only the red channel with gaussian, radius 10
This seems to be one way of getting rid of the big splotches
- Select original layer, decompose -> LAB
- Gaussian blur the A channel (I think) which seemed to contain most
of the big splotches with radius 9
- Recompose to new image
- Tried recursive de-speckle on R+B channels of the recomposed layer,
looked quite good. Did however make a colour artefact around the
fire. We'll fix this later.
- On another layer tried same de-speckle settings on all channels,
but had weird artifacts, such as red objects "growing"
- GREYCstoration, applied on the R+B de-speckled layer, p1=0.1,
p2=0.7, dt = 178.976, sigma = 1, iter = 1
- copy above to new layer, and apply same GRYCs again. Now it looks
- apply USM, 2.5, 0.57, 3
- apply USM, 0.6, 1.1, 6
- LAB decompose original, gauss blur A,B 11, recompose copy below
- use opacity to combine double-USMed layer with above layer to
achive desired effect
- make a selection around the fire on LAB A blurred fire, and give it
a bit of a selective gaussian blur. We'll use this to fix the colour
artefact on the fire
- now remove all unneccesary layers (we should have the double USMd,
AB blurred, and fire layers
- open file as layer, the highlights-converted file, turn off visibility
- The highlights layer should be first, then the fire, then the rest
- adjust fire layer opacity till it looks good. For extra points use
a layer mask, and paint it to transparancy on all the fire-layer bits
that isn't actually fire.
