Hi,
I have the Kindle version of this book since January. Overall it's a good book... with some errors. I have already reported to the editor a problem with the discussion about the Bayer matrix (section 9.2.1 The technical side of input sharpening). I just discovered another issue with the description of the Levels tool:
Section 6.3 | fig. 6.8
Shadows, midtones, and highlights each have two sliders— the upper ones determine the input and the lower ones the output values. You can also set black and white points by clicking the appropriate area in the viewer with the Shadow and Highlight Pickers.
and Quick tip below
It helps to imagine the lines drawn by the shadow, midtone, and highlight sliders as a kind of funnel. If it’s broader at the top than the bottom (that is, V-shaped), the input tonal values have been compressed, the histogram curve shortened, and contrast increased. If the funnel is broader at the bottom (that is, A-shaped), contrast is reduced and the image will have less punch. In other words, the Levels tool adjusts the distribution of tonal values to form either a narrow jet or a broad spray but always using the tonal values available in the original image file. The tool cannot create and add new tonal values.
As far as I know, in the Levels tool, input levels are specified at the bottom of the histogram and output levels at the top of it, like in any similar program. All the explanations in the Quick Tip are therefore wrong : in the V-shape case contrast is increased because the output values are expanded (larger range) while in the A-shape case, contrast is decreased because the output values are compressed (shorter range).
Or am I really that dense?0 -
If you're dense then I'm dense too, because that's the way I understood the levels tool works – input values at the bottom, output values at the top. 0
