Radial Blur For Solar Eclipse Post-Processing

[derekn38784682]

I'm doing some post-processning on some images I took of the total eclipse.  I need to apply a radial blur to a copy of a layer.  However,  the moon/sun are not exactly center in my images.  I've read that you have to shift your image so the radial blur can work properly.  However when I do that and then apply the blur, I get an odd warping on the right and lower portion of the empty canvas (due to the shift to center the image).  See image below.  How can I prevent this from happening?

Thanks

Did you apply the Filter as a Smart Filter?

I think I resolved my problem.  When I centered the image, I failed to select the full image prior to applying the Radial Blur.

Would you mind spelling out for me what you mean by "selecting the whole image?"  I have the same problem.  It seems like my whole image is selected, including the blank canvas.  If I crop the image, it goes back to off-center.  Move it back to center, and I get the canvas edges again.  Very frustrated.  Thanks in advance.

Well, I don't 'think you can select your canvas.  By performing a Select All, that selects the entire image on your canvas.  You should be able to turn your rulers on and use Percentage.  Make a horizontal and vertical ruler line at 50% for each.  Then do the select all on the image and move it to be centered on the ruler marks.  Only then you can perform a proper Radial Blur.

Hope the helps.

Thanks for the response.  I do all of those steps.  When I move the image to center it, it exposes part of the canvas.  Then the radial blur actually blurs the exposed part of the canvas into the image, with results that look just like yours.  How are you able to avoid blurring the canvas?

I'll be careful to Select All, or maybe try to constrain the blur to within a marquee-defined area. 

Would like to see your finished photo...

Is the image staying selected when you applying the Radial Blur?  That is the only thing I changed when I was having my issue of bluring into the canvas.
