This is really helpful for making your pictures look way better. First, open up your image.

Then, go to Layer >> Duplicate Layer. A layer identical to the image should have been produced. Select this layer and go to Blending Options >> Blend Mode >> Overlay. ( Blending options is accessible by right clicking on the Layer inside the Layers window )
Now go to Filter >> Blur >> Gaussian Blur and instead of having the radius at one, set it to around 5 to 10.

This is my flower now. It looks much brighter and fragrant!
