webuxer Posted July 23, 2017 Share Posted July 23, 2017 Hello, I was wondering if someone can do a quick tutorial on how to accomplish this effect in affinity photo: damnedghost632 1 Quote Link to comment Share on other sites More sharing options...
altae Posted July 23, 2017 Share Posted July 23, 2017 And why do you ask this in the beta section? Do you think you'll get an answer here? Don't you think the beta section is, well to talk about the beta releases Quote Link to comment Share on other sites More sharing options...

toltec Posted July 24, 2017 Share Posted July 24, 2017 This is only a quick, rough job to explain the technique. Original image Select the background Refine the edges (Refine) Apply a blur. Layer > New Live Filter > Lens Blur. There are other blurs that would be suitable, depending on what result you want. Gaussian Blur, Lens Blur or Depth of Field Blur. Same technique for each.

toltec Posted July 24, 2017 Share Posted July 24, 2017 Oh yes. I wondered why I had an extra image Trying to do too many things at once Apply a gradient to the filter mask with the gradient tool. Black to white. Obviously this is a bit more subtle than the rather freaky Photoshop example. But you can apply as much as you want IanSG 1 Quote Windows PCs.

Just curious but what in particular do you find awful about Affinity Photo's Lens Blur filter? It includes essentially the same adjustment parameters as the Photoshop one & unlike the PS one in Affinity Photo is a live (non-destructive) filter.

IanSG Posted July 24, 2017 Share Posted July 24, 2017 The problem I find trying to produce a shallow depth of field effect with the methods described above is that the in focus subject bleeds into the blurred background. That's not too bad when the subject and background are of similar colours, but it's horrible when they contrast. I've worked round this by cutting out the subject, cloning the background into the gap, applying the blur and then pasting the subject back in. Next time I'll take toltec's advice and use a gradient blur. Quote AP, AD & APub user, running Win10 Link to comment Share on other sites More sharing options...

On the second thought I think it was the combination of gradient mask fading and (what was probably most important) difficult background - greek beach with a lot of pebbles. Full frame blur looks quite normal. Quote Link to comment Share on other sites More sharing options...

The gradient tip is great though - thanks! Optoreba 1 Quote AP, AD & APub user, running Win10 Link to comment Share on other sites More sharing options...

Have you included the silhouette in with the gradient... and clicked "Protect Alpha" in the blur settings? I get no blur on the hat (for example) bleeding in...

No, I hadn't - I'll do it properly tomorrow but a quick test looks like it's fine. Thank you!! Quote AP, AD & APub user, running Win10 Link to comment Share on other sites More sharing options...
IanSG Posted July 25, 2017 Share Posted July 25, 2017 Sadly, preserve alpha doesn't do it. I've got pale heads against a dark green background, and as the blur radius increases you can see a halo developing around the heads.

toltec Posted July 25, 2017 Share Posted July 25, 2017 OK, changed the approach somewhat due to the nasty edge (halo) that sometimes appears. I used to paint it out with the blur tool, but this is faster and better, IMHO. A Select the model B Refine selection C Duplicate the selection of the model onto a new layer D Hide that layer E Remove the model from the background layer by inpainting or clonng. F Apply lens blur G Apply gradient to blur mask H Restore layer of model Result Quote Windows PCs. Photo and Designer, latest non-beta versions.

All you need is a mask that looks like this, and you'll save yourself a lot of time and effort! Quote Link to comment Share on other sites More sharing options...

IanSG Posted July 25, 2017 Share Posted July 25, 2017 I was right - we're at cross purposes! It was suggested that the background could be blurred using a particular method - I was just pointing out the problem of using that method. That said, I really need to make better use of masks, so thanks for the prod Quote AP, AD & APub user, running Win10 Link to comment Share on other sites More sharing options...
