Default Noise Removal the better way (Photoshop)

Noise Removal the better way

I know that most of you people would think that there is a despecle feature in Photoshop.

Well this method provides better results!

Step 1: Open the Image
Step 2: Convert the Image to Lab Colour by Image --> Mode --> Lab Color
Step 3: Goto the channels pallete and select Channel "a"
Step 4: Filter --> Blur --> Gaussian Blur (5px)
Step 5: Now select Channel "b"
Step 6: Filter --> Blur --> Gaussian Blur (5px)
Step 7: Now select Channel "Lightness"
Step 8: Filter --> Noise --> Despecle
Step 9: Image --> Mode --> RGB Color

Here is the difference...

Original Image


After Normal Despecle (Coloured Spots)


Using my Method (No spots)



Any comments are most welcome

First of all the 14.4/28/.../2MBps is just to tell you the approx time the file will take to download on a specific internet connection... Has nothing to do with compression...


Then the quality is the quality of an image... The higher the quality the higher the clarity but higher the filesize...

Better option would be 6~8... But photoshop is a poor compressor of files... So better use ACDSee to compress files after they have been saved in Photoshop...
