Smooth Bokeh ?



A combination of PS ‘Lens Blur’ and ‘Gaussian Blur’. Lens Blur alone left a ghost outline so a bit of Gaussian needs to be added to remove this.

smooth bokeh with a mirror - only 2 possible explanations, either photoshop or witchcraft (or maybe a combination of both). nice job!

Thanks Guys. I like the Tamron 500mm Mirror and it is about the most practical way of getting to 500mm. The Donuts on the Tamron are smaller than other mirrors, much smaller and controlable than my 300 Rubinar. I thought this photo was a good test of 'Blurring them down' as there is a lot of back light on the subject.

Nice!

The hard part is the masking, right?

You don't make a mask. Just put the blur on an underlaying layer and selectivly erase what you want. It takes about five minutes

Did you erased in the top or in the bottom layer?

Make a Dub layer. Hide the top layer and put 'lens blur' on the bottom layer, add a bit of gaussia blur for effect.

Go back to top layer and use eraser brush small soft about the size of smallest donut and 40% opacity. Go over donuts and other bits you think need it.

When adding somethin via another layer it is often better to do it on an underlaying layer and then reveal, rather than trying to remove the unwanted part of what you are adding from your main picture
