When you need to make really subtle refinements using Quick Develop in Lightroom, Shift -click on any of the icons to cut the default amount of change applied in half.
Here are the default values for the single and double arrow icons (adding the shift key would cut these in half):
- Exposure 1/3 stop / 1 stop
- Contrast 5 and 20
- Highlights 5 and 20
- Shadows 5 and 20
- Whites 5 and 20
- Blacks 5 and 20
- Clarity 5 and 20
- Vibrance 5 and 20
- Holding down the Option (Mac) / Alt (Win) key toggles the Clarity option to Sharpen and the Vibrance to Saturation (which also make changes in increments of 5 and 20).
- The Temperature and Tint sliders are dependent on the file format. When working with JPEG files, you guessed it, the changes are in increments of 5 and 20.For raw images, the increments for Temperature and tint are also 5 and 20. However in this case they are being calculated in relative percentage terms. (Camera raw translates the relative percentage amount to the absolute temperature and tint value using curve functions – both are quadratic and perhaps not as obvious!)
