Isolate and Sharpen Image

  • April 22, 2023

I have an image to which the lower half of the image is blured assuming this is the outcome of the original picture. I would like to remove this blur and isolate the other parts of the image which have no blur. I tried smart sharpen but the results are not what I expect. 

Is there a method to which I can use a gradient to control the blur so I can isolate where I want the image sharp ?

Without seeing the image it is hard to advise specifically.

You could apply your sharpening as a smart filter and use a mask, or you could take the image into a third party deconvolution sharpening filter and mix it with the original using a mask. In either case, the mask could be based on a gradient or on an extract from the image itself using a separate filter such as find edges.

Unless you have room to downscale, I find removing DOF in Photoshop is a struggle. I suggest AI 🙂

What method of AI did you use ?

If you think the Filter High Pass can achieve the same as AI sharpening you might not fully appreciate the difference between the two concepts. (Which is not to say that AI sharpening might not still produce »nonsensical« results in some cases.) 

 

Please post the image in question. 


The AI sharpening along the edges of the desk are clearly; which I'm not able to acheive with the high pass filter. I have set the blend mode to overlay with the highpass filter layer above and the original image layer below. Any suggestions on how I could fix; I know there are touch up methods for this exact issue ?

The image is a table with depth of field. I want to remove the portion of the image with depth of field to further minipulate the image. 

The image is; 340349851 in Adobe Stock.
