1. In HSL Set all "Saturation" Sliders to "0" for a 'Global' effect (Hint: Make a Preset when you do, then it only takes one click!!)
2. Paint with adjustment Brush and "Saturation" set to 100. For specific areas when you want the color restored.
Working in Lr6, want to change a colour pic to B&W, then change selected areas back to colour, eg child with medal, want the child and background in B&W, and then bring back colour to the ribbon and medal.
No need to use the HSL sliders, which will produce a less than perfect B&W image.
1) Set the Adjustment brush tool to -100 Saturation, large brush Size, 100 Flow, and 100 Density, and paint over the entire image until it is fully B&W.
2) Hit the Escape key to deselect the current Adjustment brush pin. Set Saturation to +100 and adjust the brush size so it is small enough to fit into the medal area of the image. A small Feather setting (50 to 75) may help, but keep Flow and Density both at 100. If you paint outside the medal hold down the ALT key, adjust to a small brush size, and paint over the area that shouldn't be in color to erase it.
Thank you very much, appreciate your help!!!
thank you appreciate
Thank you to everyone that took the time to help, greatly appreciate it......
Just want to add that wobertc's suggestion to set all of the HSL Saturation sliders to 0 to create the B&W image works the same as a -100 Saturation brush–I stand corrected.
That said the best results can be obtained using the Basic panel Treatment> Black & White tool to create the B&W image. It uses the HSL panel's 'Black & White Mix' luminance sliders to automatically create a more natural looking B&W image. If Adobe ever adds the HSL panel to the Local Adjustment tools you will be able to set all of the Saturation sliders to 100 and paint color back into the 'Black & White Mix' image. For now you'll need to use Edit In> 'Open as Layers in Photoshop' using the original image and a virtual copy with 'Black & White' Treatment applied. Make sure the B&W layer is on top and then use the eraser tool to reveal the color layer where desired.
I think we like to agree there are several ways to achieve a 'pop color' result.
I would like to expand on the suggested method of De-saturating all sliders in HSL- and why I recommend it.
1. You can Brush-back areas of color by setting a brush to +100 saturation.
OR: and these are the good parts!-
2. You can also recover ONE color by simply pushing that color Saturation slider back to normal. (eg. Red)
3. If your color (eg. Red) returns to unwanted parts of the image- then a Brush -100 Saturation will remove it.
4. If you expand the HSL panel to show "All" sliders you still have FULL control over the individual color channels for "Hue", "Saturation" and "Luminance"- meaning you can do better than the any B&W auto-mix.
5. Using the Basic panel B&W auto-mix, locks the image as B&W- no brush can change that. (no colors!)
6. Using B&W in the HSL panel also Locks the image as B&W- only luminance can be changed (no colors!)
In other words do not use any click in Lightroom that says " B&W " even on the HSL panel!
This screen-shot is simply Desaturation of all channels, moving the red channel back up to +100 and adding some red "Luminance". Note that some red also appears in the background- this is brushed out with a -100 Saturation Brush.
And the "Luminance" channels can change all color channels for luminance. (ie. contrast in the monochrome)
AND you can use the TAT (Targeted Adjustment Tool) to alter ANY of these sliders!!
Brushing away 'unwanted' areas of color that 'returned' with the "Red" slider-
