Photoshop Technique

I do know that we are turning to study Adobe Flash in class, but I am still fascinated with Adobe Photoshop. Therefore today, I want to write about a Photoshop technique that is applied widely in the photography.

This picture above is applied some effect to make it look colder by adding more the blue color. Now I will guide you step by step how to make this effect. Let's start with the original picture.

Step 1: Open the picture with Adobe Photoshop and then Duplicate it by going: Image->Duplicate

Step 2: on the copy of your picture, go Image->Mode->Lab Mode, and then you go to to the Channel tab
Step 3 (Working on Channel a): click on the Channel a to active it and then you go to Filter->Gaussian Blur , set 5 pixels

Next, you press Command+L or Control+L on Windows, and a tab should appear. Now you set the Input Levels: 77, 1.00, 255

Step 4: Click on the Channel b, for this Channel, you do not need to apply Gaussian blur effect ^_^. Next, press Command+L or Control+L on Windows, you should set the Input Levels: 77, 1.4, 255

Step 5: you should select all the channel in the the Channel Tab( as the picture below)

And then, press Command+C or Control C on Windows to copy these channels

Step 6: go back to your original picture, and then press Command+V or Control+V on Windows to paste

And then you set the Mode of new layer to Overlay, and then you would set the opacity from 60% to 80 %.
