Depth of field effects (dof) happen in all real optical devices to a certain extent. It is heavily used in photography and film as a style element. In computer graphics, dof is usually generated using ray tracing techniques which increase rendering times considerably. With the Lenscare plugin depth of field effects can be generated fast as a post-process. It uses a depth buffer for its calculations.
Apart from its speed and quality, an important advantage of a depth of field post filter is that you are able to test various focus settings easily without re-rendering the whole scene. That way you can quickly get an impression of what settings work out best for your shots.

IntroductionLenscare moves depth of field and out of focus generation to post production.If you need high quality camera blurs with the flexibility of 2d postprocessing, Lenscare is a great choice. It can get you rid oflong extra 3d rendering times.
The key aspect during the development of these filterswas to match the real thing as good as possible.Lenscare is available as plugins for Adobe After Effects and Photoshopcompatible programs.Depth of FieldDepth of field effects (dof) happen in all real optical devices to a certainextent. It is heavily used in photography and film as a style element. Incomputer graphics dof is usually generated using ray tracing techniques whichincrease rendering times considerably.
The depth of field plugin generatesthose fast as a post process. It needs a depth buffer for its calculations.Out of Focus'Out of Focus' isa fast version that works without depth information. It creates a blur withconstant radius over the complete image and is a good complement to 'Depth ofField'. It offers some extra functionality as well. It's possible to use acustom drawn lens in addition to the generateable ones. 'Out of Focus' alsooffers background distortion for semi transparent areas.
But slight distortions help adding to the believability of your comp.To experience this effect try holding your finger in front of your eye so thatit is out of focus. Now look through the blurred region on whatever is behind.Move your finger around slightly to see the effect better. Apart from its speed and quality, an important advantage of a depth of fieldpost filter is that you are able to test various focus settings easily withoutre-rendering the whole scene. That way you can quickly get an impression whatsettings work out best for your shots.Speed'Out of Focus' effects is a speedy 2d blur and can compete with any existingsolution. 'Depth of Field' is very fast for what it does. In a lot ofsituations you can save hours of render time for just a couple of seconds perframe in post processing.
This is a big advantage especially with high qualityglobal illuminated renders. Imagine what you can save on animations. Check outthis of Brazilsdepth of field with Lenscares. (Brazil: 190 minutes vs. Lenscares dof: 6seconds + 4min no dof Brazil render). Of course Lenscare takes advantage ofmultiple cpus if present.QualityPlenty depth of field and out of focus solutions are available. Fortunately forus most don't simulate camera effects properly.
They don't do their namesjustice because their algorithms are not physically based. They are justmethods that look nice in some situations but fail in others. A common mistakefor 'depth of field' filters is to 'blur' all the surrounding pixels withoutregards to their depth values. Usually this results in ugly glow effects inregions with great differences in depth. Isa comparison of the After Effects standard depth of Field filter compared toLenscares. The artifacts described above can be seen pretty good in the AfterEffects version. Please note that the After Effects version was honestlyadjusted to look as good as possible.
Stochastic or super sampled ray tracedblurs suffer from artifacts if not enough samples are used. Lenscare doesn'tproduce any such artifacts. Of course both filters support 16bit image format.Judge the quality for yourself and take a look at theor download the.IssuesThere are common unavoidable problems that all post processing depth of fieldsolutions have. It's not possible to blur reflections or objects behindtransparent objects correctly. This is obvious when you see that the depthbuffer can only hold one value per pixel.
Our Lenscare plugins move depth of field and out of focus generation to post production. Knowing that there is a lack of solutions for real camera blurs we tried to work out our algorithms to come as close to the real thing as possible.Lenscare for After Effects (professional Lisence) 1.1 Animation software developed by Frischluftcom.
