Step 5: Set Black and White Points

Second: Choose Image -> Adjustment -> Levels, choose the "Set black point" and choose a dark area on your photo, see how the overall color changes. In this photo I choose the right-side of the forehead.

good tip
great instructable!

&nbsp;I've done something similar myself, but with a different aproach, and it renders similar results. Also since my MBP is out of business for upgrades, i've done this in a hp mini netbook with paint.net. Here is an example
&nbsp;Gud job..............
thanks for all the instructions & tips..my work.. :)
You can make a BW to Colour gradient, it looks pretty cool and works well with a far away background but a really close middle ground. Get Picture->Create copy ->Delete all colour on one copy->Return picture to RGB Colour (it is still blackandwhite though)->Make sure BW picture is below the coloured picture ->Create layer mask for coloured picture->Make sure layer mask is active (double border on the icon) ->Go to gradient->Radial gradient (Its circular)->Foreground to transparent gradient (its in the presets). Then do the gradient!. If it doesnt work try a Black to white gradient on the layer mask.
One of the challenges with this method is posterization. If you look at the histogram on the levels palette in your screen shots you will see that you are getting some. The graph should be a solid black. when it is broken up (looks kind of like a bar graph) your image is getting posterized. If you don't do it too bad, you won't see it on the computer but when you go to print you will not have a smooth gradation (there will be harsh lines between the different tones of shadow transition edges.) If you do your black and white with a channel mixer adjustment layer and a careful adjustment in curves or levels (also an adjustment layer) you can avoid damaging your image in this way. All that being said, my favorite method is to use a custom quadtone.
Great instructable, learnt a few new things here! Many Thanks.
i could just desaturate, darken and export with a low quality
Very informative, thank you.
Thank you for this instructable!!! Like an amateur, I've always just been using the 'desaturate' option - I thought the photos looked good as is, but now I can see how much definition this really adds, and how flat my others look. Time to make another action. Thanks again! :)
Thanks for a great instructable! I always favor black and white photography or sepia tone-classic.
they look filipino.
He's actually Thai, my best friend.
nice look, but you forgot to mention that you applied "Auto Levels" before dropping saturation. i can clearly see that in the screen shot.I mean auto levels itself fixes the image.then you basically just did a brightness/contrast adjusting which would have been easier to make because you just move a slider rather than playing blind with gray shades .
I think it's also a good idea to use Auto Levels, just because it's easier. But I do prefer to adjust the tone by myself, sometimes there're details that I just want to show/hide, but Auto Levels wouldn't listen to me. The idea of using Brightness/Contrast is also good, but I like changing the shades because I found the color more balancing.
very nice, I will share with some of my buddies in my graphic arts class.
Have you looked at Photoshop's Quadtones? I got the <a rel="nofollow" href="http://www.kenrockwell.com/tech/photoshop/b-w.htm">tip</a> from <a rel="nofollow" href="http://www.kenrockwell.com">Ken Rockwell</a>'s site. They give a very nice conversion of the colors (of course, the noise and darkening are still up to you).<br/>
but why though?
cause u can / wanna
as vdubya said - using the color mixer is a much better way to get decent b/w from colour shots in photoshop.
this thread's really nice... ive been using all the various Filter options in Photoshop for quite some time now, and i havent thought of the Noise application as a means to make a photo look grainy (i usually use it to grunge up photos for alternative/rock posters), since i havent considered interusing it with other features. kudos to you man. i really love photography and editting pics... hehehe check out mah photo blog: www.snaeib.blogspot.com and my editted photos blog: www.ijusthavenothintodo.blogspot.com then tell me what you think. i need another person's opinion on 'em so maybe we could exchange notes on photography too.
I've found the best way to convert a color photo to black and white, is to use the color mixer in Photoshop. Preferably use the non-destructive layer adjustment rather than manipulate the original layer. Click the "monochrome" check box, and then manipulate the individual color channels until you get a picture you like. I find that the green channel usually gives me the best results. The blue channel usually will have the worst amount of noise, so I rarely use it. From there usuing some of the techniques listed above to age the picture should give you a really nice print.
excellent tutorial - thank you
Thanks for reading it.
Excellent idea. Though there is an easier way. "Desaturate" the photo as you did, add noise (for your photo, I'd go for Gaussian at about 4%), and then just use the curve function (somwhere around: Input: 93 and Output: 78, but you can play around with the line until you get it the way you want it). Just thought I'd let you know one of the shortcuts. There are probably other easier ways, but I was self taught in the ways of photoshop (I didn't even bother with the help section, they usually lead you around in circles) and so I only know of my way, but have fun with it and perhaps I'll learn something new in your next post.
I still like the "point and click" method more, but thanks for your tip. I think this is such an amazing platform that people can exchange their tips and ideas so easily. I'm new to here.
nice classic look I like it!
You can also use the channels palette. Open it up and click on either of the red, green or blue channels. This has the effect of using the same coloured filter on a B&W photo. You can get some really nice effects. For instance, using a green filter blocks red, so your subjsect's skin will look a lot clearer.
