There are a lot of issues when using a depth map with Lens blur. I just wonder if there's anything else to blur an image (DOF wise) in PS. Image is pretty large, 6000px square.

Any experience?

Cheers

P.S.: Or are there any tricks when using Lens blur. I didn't try to blur the depth map slightly. does this probably help?

Hi neverko,

this issue arrises on the border between objects in the for-, middle- and background. All the images in the example are heavily blurred. Though the border between them is crisp like hell. I wonder if blurring the depth map in area in the back will help to supress these issues.

I wished DOF pro would work with .hdrs and you didn't have to use paypal. I'm not going to sign up with this sleazy company.

Well, that's only one web site which is run probably by only one single guy, but I stumbled across it while actually wanting to sign up with them to be able to pay on the internet. There are many pages out there describing what might go one and that their policy is a bit dubious. I'm luckily not one individual who did have any bad experiences with paypal, but what I've read, especially on some German websites, was enough that I changed plans to do business with this company. So I can't say that it is pure evil, but I won't be able to trust this company too much. Well, have a look yourself.

One thing is, that if you even sign up on their German website, all law suits which might arise during or through business, will be held in the U.S. So there's actually no chance for Germans, U.K. members, French, etc. to get into court with this company (although this might not be the case), unless you plan to get bankrupt.

There are many other issues which led me to the decision, to look for alternatives when paying for stuff on the internet.

Cheers

Yep. What helps in cases with very out-of-focus zones and lensblur, is to make a focus map instead of a depth map and render this map with a real DOF effect applied. We can't do much to change the focal point after that, but since it's like a matte pass, render is a lot faster and if we have saved the map in some FP format, we can vary its contrast levels and expand or reduce the convolution circle a bit.

DOFPro is very good too, but is too slooow with hi-res images. Other great tool is XDof from evasion3d (it's a pixel filter solution). It works well with classic and perspective camera. I've noticed also they have an stand alone solution (but I haven't tried it). At a compositing packages level Lenscare is the best thing that I've tried, but I don't think it works at 6000p.
