Hello.
Example 5 was a more difficult image. It did not have much to chang with respect to the thresholds. I did apply some basic adjustments using both Lab and HSB. Please explain the advantages/disadvantages of HSB over RGB and LaB. Please give me your advice on this image.
Thank you
David
CM Week 1 Example 5
I'm not sure I would even tackle this one in HSB...I'll try taking an HSB swing at it next...But..in LAB it is a simple correction with a few things to note...
1) Shadow and highlight thresholds are the first step. You need only have a few pixels pop out in the highlight end. The shadows can take quite a bit more. In fact it adds drama to the image to deepen the shadows.
2) Over saturation in LAB will steal the highlight details. See screen shot. I kept the details in the petals...

Hello.
The reason I tried Example 5 in HSB was because I thought that the Hints Video mention HSB with respect to example 5. I am taking another try at Example 5 using Lab. This time I used less saturation. What do you think?
Also, with respect to selecting a neutral point; Can you give a formal definition of a neutral point? Neutral Points seem especially confusing when there is no obvious choice, a gray point. Again, can you quantify how to define the best neutral point for an image.
Thank you

David,
To my way of working a neutral is the same as Gray.
Things I look for that should be neutral...Concrete (in general) Tires on a car, shadows on a white wall, shadows on a white shirt, black shoes, white shirts, puffy clouds(be careful with this one) dark clouds(again care is needed) the Idea is using memory colors; things you know from experience and observation, that should be neutral or near enough to neutral that you can start your correction based on them.
It can have any brightness from 0 to 255 in RGB. so...
RGB(0,0,0) Black
RGB(127,127,127) Middle Gray
RGB (255,255,255) White
Are all neutral.
In LAB the numbering is different but the concept the same...
L0,a0,b0 Black
L50,a0,b0 Middle Gray
L100,a0,b0 White
Are all neutral.
When we get to color by the numbers you will get a much better feel for this.
By the way you flower looks better...
