Quick tip for removing color cast using Photoshop

Actually, it is not just Photoshop, any graphic manipulating enabled software can do this, as long as it can use Level adjustment.

Steps are:
1. Open up your picture/photo.
2. Add Level adjustment layer (Layer > New Adjustment Layer > Levels...)
3. Change the upper Channel to Red and drag/pinch the most left(shadow) and right(highlight) arrow sliders so they are placed where the information begins in the histogram view of the dialog.
4. Do it for the rest of the channel Green and Blue. Voila, your picture will be color corrected.
