These days of color photographs have moved a long way from those black and white images. Sometimes you may want to give a vintage look to a color photo as a spcial effect. It is not at all difficult. It can be done in any version of Photoshop. Just follow the steps below.
Step 1 : I have opened this free stock photo in Photoshop. You can download this photo from here.









Step 7 : This brings up the Color Picker. The column in the middle is called a Spectrum. You will find a slider at the bottom of Spectrum. Drag it up with the cursor till the color changes to Orange. The Color I have chosen is 'e3821a' . You can alternately enter the value in the box at the bottom marked with #. Click ok.




This is how the Layers pallette looks.



The Foreground Color changes to the color picked.





Step 17 : Reduce the Opacity of Layer 2 to 55 % by dragging the slider at the bottom or entering 55% in the little box.
The finished image. You can use any color for the Gradients. It is up to you.
