Focus only to one object

Diposting oleh excellcomputer on Senin, 03 Januari 2011

I have an image where there are some people on that image. I want to focus to only a girl who wear purple dresses. So I try to find some way to do that, and on blur setting, I get lens blur setting. So I try to use the technique.
Firstly, it’s better to repair the condition of the image, if you think the image is needed to repair, such as the brightness, contrast, or level of the color maybe. This step is to make the image being more clear when we are going to make it focus.
So this is the image before and after repair..
BEFORE REPAIR












AFTER REPAIR












I use brightness/contras and level setting to make the image better than before.

After repairing the image, let we go to next step, that is focusing the purple dresses girl.
Make selection on that girl. To make it quickly, I use “quick selection tool”. Actually, we can’t get perfect selection using this tool. You can see this image which shows the result of selection using quick selection tool.













To repair the selection, we can use “polygonal lasso tool”, don’t forget to set the intersect or subtract of selection using this tool. After repairing the selection, let we choose intersect by click your right mouse and select “intersect”. This step is held to turning the selection from the girl to all image except the girl, because the blur setting will be given to all image except the girl. So that the girl image will keep on focus.
After selecting intersect, let us go to toolbar menu, than select blur => lens blur.

















Then there will shows the lens blur setting on your screen



















change the setting according to your mind. In this case, I do not change anything, just let the default setting. After you think that is enough on setting the blur, select ok.
To make the image better, I try to edit the image by duplicate than change the blend mode on “soft light”. Than merge visible layer by press Ctrl + shift + E.
So the result will be…
