Hi,
I have an illustration between Channel Mixing and Desaturation methods for BW conversion from colour pic. #1 is the orignal colour pic. #2 is converted by Desaturation method in PS and #3 is converted by Channel Mixing method. #4 is the same item shot with BW mode from S3 IS.
From the look of #2 and #4, it is obvious that they are very similar and should be converted by the same technique.
Now lets compare the 2 methods. Look at the right most 2 pegs (the half buried red and blue in #1), in #2, they have very close tone (due to the same luminance value) although from #1 they are diff in colour. But in #3, they are of diff contrasting tone. This is posible due to channel mixing in the RBG colour.
Hope this sharing can contribute to those interested.
#1 Original Colour
#2 Conversion by Desaturation
#3 Conversion by Channel Mixing
#4 BW Mode from S3 IS
Just hope to share will all what I have just learnt and please feel free to comment.
If you have other method, please share if you dun mind.
So that I can learn another method.
Thanks!!
