First open your Photo in Photoshop and then remove all the color ( it should be black and white), then unlock the background layer or you can simply create a duplicate of background layer so that changes does not affect our original photo
Then we need to section our image in three parts using Guide. Simply go to VIEW - NEW GUIDE, Then set position to 30 or when Move tool is selected after creating a new guide you can set the position you desire by dragging the lines. Repete same procedure to create as many guides as you like
Note: Make Sure Snap To Guides Is Turned On
Once done, Grab the Rectangular Marquee Tool to start dragging a selection around our first section
Now create a new adjustment Layer Hue/Saturation for the first selection, Check colorize and preview box
Change Blend mode of this Layer to color
Repeat same procedures to colorize second and third Sections
Go to View > Clear Guides to remove the guides from your photo
Well that's my final photo
