Getting Rid of Colour Cast
I am often asked questions about getting rid of colour casts in an image. This has been discussed in earlier issues, but since the question often repeats itself, here are two very simple ways in which you can colour correct your images. In both the cases, we shall consider that the image has only one colour cast (often, images can have more than one colour cast).

Method 1
This is the simpler method. It works most of the time. Do give it a try; just because it is so simple, does not mean it cannot be effective. In daylight, artificial light White Balance ( Incandescent light) was used, which has caused the overall blue cast. 1. Open the image in Photoshop. 2. Create a copy of the Background by dragging the Background Layer to the ‘Create a new layer’ icon at the bottom of the Layers panel ( In case your Layers panel is not open, press the F7 key to open it). ( PS 1 shows the new Background copy) 3. Go to Image > Adjustments > Match Colour. ( PS 2) 4. When the Match Colour dialog box opens, merely check (tick) the Neutralize checkbox and click OK. ( Don’t do anything else). ( PS 3) 5. If necessary, proceed with the usual basic editing ( like Levels or Curves etc) to punch up the tones. In our edited image, Brightness/Contrast has been slightly boosted in the lower part of the picture. 6. Save the file using the Save As command.
