Always use plumbers grease when replacing faucet seals? In Photoshop what is the best way convert color to B&W?

I am out of grease but I have the seals. Don't want to run back to the store.





I know about desaturate but it seems primitive and crass. Any other suggestions?Always use plumbers grease when replacing faucet seals? In Photoshop what is the best way convert color to B%26amp;W?
No grease will over time cause abrading which will shorten the life of the seals.





Set Saturation to -100


Use the Levels tool to adjust the black threshold, white threshold and then use the mid-tone slider to produce the ';best'; image in your opinion.





This all depends upon you using a calibrated computer monitor.Always use plumbers grease when replacing faucet seals? In Photoshop what is the best way convert color to B%26amp;W?
Desaturate is not really that usefull for black and white conversion.





Use the monochrome checkbox in channel mixer when converting to black and white. Alternatively, use the rgb channels. Delete the channels you don't want then convert your image back to greyscale/rgb. Finally use Levels to adjust the black and highlight points. Move the middle slider to adjust lightness and darkness. Then use Curves to increase contrast by making a slight S bend.
Use the channel Mixer when converting to Black and White





Mix how much red, blue, cyan, and all other colours in there to get the black and white that suits your needs.





De saturation and conversion to Gray scale barely cuts for my black and white needs.
Usually I do the Marc Williams method:


I use a BW Gradient map, then adjust levels to taste.





Occasionally I use channel mixers. I do sepia tone in channels.





Have no idea about plumber's grease.
The best way is to use Nik software 'Silver Efex Pro'..
