Black and white filter
Below is a photo taken at a club with flash and a long exposure, close to a second. When you choose Black and White in the top right near Basic develop settings, a filter is applied based on the strength of certain colours in the photo. In this situation, a straight colour conversion to -100 saturation seems to darken or hide the blue ambient light, while the auto B&W filter brightens the blue/purple channel.
Another way to change the brightness of certain areas is to leave saturation at -100 and then change the white balance. Skin tones become dark and unnatural at cold white balance settings. For photos of a band on stage, changing the white balance in black and white can even seem to change the direction of the lighting, such as having red lights from the left brightened and blue lights from the right darkened at a warm white balance, then the opposite at a cool white balance.
- Press F twice for full screen view.
- Control + Tab to hide or show side bars.
- Press J to show clipping.
- Right click on the background past the edges of a photo and change the colour from white through black. I leave it on black with pinstripes.
- Control + Shift + Alt + E: exports the selected photo(s) with the same settings (size, folder, output sharpening etc.) as the previous export.
- Confirm cropping by pressing Enter on the keyboard. instead of clicking Done.
- Press X to rotate the cropping outline by 90 degrees.
- Press O to cycle through overlay modes. The default is the a big grid. The rule of thirds is very useful and there is a variation on the rule of thirds which can centre and strengthen compositions. The Golden Spiral is also great and I find it often more suitable when cropping 4:3 rather than 3:2 ratios.
- Press Shift O to rotate the overlay (there are many ways to display the Golden Spiral.
If you have tagged a photo, cropped it and edited it, then the picture and the bottom will look something like this, which each icon indicating the step was performed.
If you are in Develop mode and click on the tag icon, you will be taken to Libary view and the tag section. Similarly, clicking the +/- button will take you back to Develop mode and the middle one goes to crop view.
