Hello.

I have included an image that was adjusted using the HSB mode.  I believe it did an interesting job on the pumpkins. 

Would you please post a Rule of Thumb summary of when to use RGB, Lab, HSB and CMYK as defined by CM?

What do you think of Exercise 3 - the pumpkins?

Thank you
David

David,
You have desaturated these far too much...The gray "mold" and gray stems means you took this one too far.

Rule of thumb...??  hmmm Let me think on that one a bit.  tick tock...tick tock... ;)

In general I use HSB for specific trouble spots; the eyes in a portrait, over saturated colors like the shirts on the kite fliers from last week, too much red in skin tones...
I use LAB when the color is pretty good overall or when there is a uniform color cast on the image.
If the shadows are different from the mid tones or highlights then I use RGB to correct the color.

In general...My current work flow goes something like this...actual mileage may very...see dealer for details...

1) Color Correction.  I try LAB first but usually end up doing a "By the Numbers" correction in RGB.
2) Recover shadows and highlights; I use various techniques to do this from the simple "lizard tale" to multiply or screen with masks...I sometimes even use the old clone stamp...
3) Adjust the overall tonal range of the image.  I use LAB, Channel copies, Curving single channels and setting the layer to Luminosity,  shadow/Highlight, and/or exposure.  The idea is to get all the tonal range possible into the image by hook or by crook...
4) Boost Color...LAB for a fast saturation slider or for some color specific color contrast moves...We cover some of these later in the class.
5) Sharpen.

Hello

I have tried the pumpkins again; this time paying closer attention to saturation and brightness.  What do you think?

Thank you
David

Much better...

I think the greens are giving you trouble but they are hard in HSB.  I would not try for them personally...

Good job.
