Lightroom 4 Tip – Blacks and Whites
Here’s a cool little tip that’s actually been around in Lightroom for a while now, but it makes MUCH more sense with the renamed sliders in Lightroom 4. Basically, I get asked what the whites and blacks sliders are for a lot. I use them to set the white and black point in the photo. Usually, you’d think you have to turn on the highlight and shadow clipping warnings (by pressing J) to use them but there’s another trick. Next time, try just holding down the Option key (PC: Alt key) when moving the sliders. For Whites, everything will turn black as you drag it to the right. When you start to see some details popping up (don’t worry too much about the color) that means you’ve got a good white point.

Then drag the black slider and everything will turn white. When you start to see a decent amount of black specs showing up, then you’ve got your black point. Setting a white and black point have been around for a while in Photoshop, so it’s definitely nice to see them show up in a more consistent way in Lightroom. Enjoy and have a great weekend!

Hey Matt,
Thanks for that tip! I was wondering what those sliders were for! I just used them to bring out some contrast. Wow, I like this tip!
Thanks,
Dennis
Matt: I typical set these in LR with the option key. However, I’ve tended to set the black point as soon as I see any black show up. In looking at the histogram and the clipping warnings, it seems to me that that’s the place where I begin to crush/clip the blacks and lose some detail.
Is that too conservative?
Can I send more of the photo to pure black and have it show up black when the option key is held down? Does this depend on whether I’ll be printing the photo or just displaying it on screen?
