week 1 example 5 own photo

[mikemeister_admin]

here's a photo from my library,
it represent stairs from an old XVIth century mansion in my town, Toulouse (France)
there's an obvious lack of details in the shadows, while the sunny part is over exposed.
I'll post the result s a reply to myself...

[mikemeister_admin]

I've done it with CM set highlights/shadows and also neutral
but I failed to avoid yellow cast of the over exposed part
I tried to make a color correction with curves in order
to "standardise" the 2 parts but as the density were
quite equal, the yellow cast became worst and worst,
even with local curves command, even with the
blue channel put at the max density there was
still yellow in the image so I got stucked (so I had to post unfinished work)
tried in LAB mode, no better results
Can anybody help me with that stuff?

let's try this...in LAB

Step one:  Set a neutral on the white pipe. (image4)

Step 2: Set shadow and highlight.  (image 5)

Step 3: darken the shadows under the stairs (image 6)

Step 4: restore the rest of the curve smoothly...(image 7)

Step 5: switch to the B channel in LAB place the mouse on an area where the shadows turn too blue and rigt click. Choose "mark" from the menu to mark the area of the curve for adjustments. (Image 8)

See next post.....

Step 6:
now that you have the mark on the curve (image 9)
you can "pin" the curve down to one end using the pin curve function that we would be introducing to you later in the course.

right click on the center of the curve and select the "pin curve" function from the menu. (image 10)

Pin the "lower right" in this example.  I want to pin the yellow since it is the blue that is the problem. (image 11)

Step 7:  Drag the mark down tword the center to "kill" the blue values at and around the mark.  The closer to the center the more "not blue" the pixels become.  (image 12)

Step 8: increase the saturation using the slider.  (image 13)

There you have my version of your image...Actual milage may vary...Void where prohibited....

or wait later that the image fits the lessons (think I'll try now)

another thing, 1/I have problems to darken the stairs the way you've done in the capture.
It seems that I don't have any zone to write my own digits as you done with 35-19
2/ You seem to have a zone system scale on your lightness curve, mine is in %
Have I missed a version?

[mikemeister_admin]

ok, I played with the options and I was able to set my grid in the zone system scale, I think I should read the whole help file first :)

Please do read the manual...there are tons of items in there that will help you along...

Keep asking questions even if you answer them yourself..it helps everyone.
