To make an introduction, do this short exercise :
- Use your colorful kiwi image from the former session.
- Make selection to the four kiwis. Make refine edge. Then do : menu Selection -> Inverse, so you get the invert area are selected.
- Put a gaussian filter, click menu Filter -> blur -> gaussian blur. Set the radius according to your taste – you can see the preview if you check the preview optional checkbox

- Now you would get this final image. Save as jpg.
Photoshop provide many types of filter that you may find in “Filter Gallery”. Filters are used either for art purpose or correction.
There are some notes you have to remember in working with filter:
- Filters are applied to the active, visible layer or a selection. Most filters can be applied cumulatively using the Filter Gallery. All filters can be applied individually.
- Filters cannot be applied to Bitmap-mode or indexed-color images.
- Some filters work only on RGB images.
- All filters can be applied to 8-bit images. Only the following filters can be applied to 16-bit images: Blur, Average Blur, Blur More, Gaussian Blur, Motion Blur, Noise, Add Noise, Despeckle, Dust & Scratches, Median, Sharpen, Sharpen Edges, Sharpen More, Unsharp Mask, Stylize, Emboss, Find Edges, and Solarize.
- Some filters are processed entirely in RAM. If all your available RAM is used to process a filter effect, you may get an error message
You will enhance your skill with some next exercises.
