Using Brightness / Contrast

(no, I am not going crazy)

If you look at your monitor you'll have a button or some knobs to do Brightness /Contrast adjusts.
If you look at your TV, you'll have a button or knobs .......
... so Brightness / Contrast would seem to be quite a fundamental image adjustment.

Then you come to Photoshop, and you discover that what ought to be the most useful adjustment of all is actually a quick way to ruin a good photo!

Here's a way to tame the B/C adjustment and actually turn it into something useful:
1) Use the Blend-if option, underlying layer, 0-127 (black) and 128-255 (white);
2) Set the layer blending to luminosity.

Quick and easy!

Quicker and easier - use the attached action.

I have read too many of your exellent tips to think that this one would be crazy, it just appears so. Will have to give this one a try. Thanks for your fresh perspective on things I thought I knew.

Upon 1st inspection, you're right: It looks like a b/c adjustment layer.

Notice:
* There's no mask (the thumbnail that normally accompanies an adjustment layer)
* If you open the Layers Palette flyout menu and check the Blending Options dialog, notice the settings for the "Blend if" sliders

Duplicate your image and apply a B/C adjustment layer and mess with the settings. Then apply the same settings to Ro's version. Seeing the difference is what turned on the lightbulb for me.

You once again are showing me things I didn't know were possible. I thank you, sincerely.

Alrighty then, dashing Danny. I get it! The b/c adjustment is less extreme, black and white wise. More subtle and pleasing.

BTW, as a BIG surprise b'day gift, my kids gave me a 5 day trip to Seattle to visit my brother next summer. I have googled 'whale watching', and several to choose from. Any recommendations??? Any other suggestions. Also going overnight to Victoria.

Thanks

Don't know if it's possible for you, but it sure would be nice if you could squeeze in some time for a short to us in Nanaimo! It's about 1 1/2 hour drive from Victoria.

Cheers
Dave

Sounds possible. I know I'm 'jumping the gun' here. Just excited. Wouldn't have done it for myself.

I used to live in Medicine Hat, Alberta and have visited friends in both Victoria and Nanaimo.

I'm sure you will have a great time no matter what you choose, and of course if you choose to visit DUV then theres a bonus for you.

I do not wish to hijack this thread, but if you get a chance to visit The Butchart Gardens in Victoria, you wont be disappointed, plenty of great photographic opportunities to be had and of course, you will enjoy the whale watching ( and the dolphins ) if you happen to come across any.
