“Warm Up” colour adjustment

  1. From the bottom of the Layers pallet choose the Create new fill or adjustment layer menu.
  2. Choose Levels
  3. Make a tonal adjustment by bringing the highlight and shadow sliders to the ends of the histogram. Adjust the midtone slider to set the desired brightness.
  4. In the Layers pallet choose Red from the channel menu.
  5. Slide the midtone slider to the left until the image appears noticeably red.  Let your eyes adjust to the colour for a moment then ease back the slider until the image does not look noticeably red anymore.
  6. Now choose Blue from the channel menu.
  7. Slide the midtone slider to the right until the image appears noticeably yellow.  Let your eyes adjust to the colour for a moment then ease back the slider until the image does not look noticeably yellow anymore.
  8. View the image before and after the adjustment by switching the visibility of the adjustnment onf and off. Make further adjustments as necessary. The image should not appear noticably red or yellow but should have a generally warmer appearance.

NOTE:  Most of the time the green channel will not need adjusting.

 

Image retouching with Photoshop


(See more “Celebrities Before and After Photoshop“)

The majority of images we see these days have had some level of digital alteration. It may be to simply correct the photographic aspects of the image (lighting, colour, sharpness, perspective etc) or may take the image to a level far beyond that which the camera captured. Although our image editing tools are much more sophisticated today, photographers have been altering their images since the early beginnings of the craft.

Digital image retouching with tools such a Adobe Photoshop allows us to elegantly alter every aspect of the image. From the simple removal of a blemish to a complete reconstruction of the bodily or facial form the original image captured by the camera can now take a radical and convincing departure.

Non Destructive Editing in Photoshop

This has become a real mantra for me when teaching. Photoshop by nature is quite a destructive application. It is easy to, in a few simple steps, irreversibly damage an digital image if we use Photoshop in the way that seems initially intuitive. Non Destructive Editing is a method of working in Photoshop that leaves the original image untouched and prevents us from progressive striping information from the digital file. Layers, Adjustment Layers and Layer Masks are key elements in this way of working.
