Cloning and Spot Removal

Photography nowadays is happening to be one of the most important part of everyone's life. Everybody wants to store there precious moments in life so that they could cherish them in future. DSLR Cameras becoming more and more famous, increasing quality of photos , makes the age marks like wrinkles, spots, moles, beauty mark, etc. clearly visible in the photos which surely does not looks nice.

Spot removal tool is very useful for making localized spot correction and cloning fixes. It can used for many things like lens spots and blemishes. To use the Spot removal tool you can follow these steps:

1. Open the file you want to remove spots from, by going to File > Open > select the File.

2. Choose the spot removal tool from the tool bar. This will open a panel and the cursor will change to crosshair.

3. Now you can choose heal option from the drop down menu. It basically replaces the spot area by another selected area (it uses only lighting and shading whereas clone brush completely clones the area). Its important to use feathering so that the edges does not looks sharp and so that edges can blend in.

4. Now you have to select the spot. Select in such a way that it completely covers the spot, my advice is to select a larger area than spot.

5. You will get two circles, drag either of them and place to a nice area which you want to choose as a replacement of spot. (Choose an area not so far from spot, this will maintain the texture)

6. You can now play with the circle resizing it or moving it to some better place, repeat the above steps to remove other spots.

Hope you find this useful!!
