Using Camera Raw or Photoshop, how can I achieve this look?
It is simply low contrast images. Drop the contrast down, possibly pull in the white and black points so that they are grey rather than white and black as well.
The images you linked to are low contrast with elevated exposure.
To get this look:
- Reduce the overall contrast
- Reduce the highlights and brighten the shadows
- Increase overall brightness/exposure a little to the right of zero
But why would you want to?
