Now, you can still use LW to write out the render buffers to separate OpenEXR files (using the Render Buffer Export image filter that ships with LW). RGBA for the final rendered image, X/Y for motion vectors, Z for depth).Īnd indeed, for the automated management of passes you need something beyond exrTrader, such as Janus or LWPassPort. changes of item visibility, surface properties, light settings, render settings, etc).Ī buffer in consists of one or more channels (i.e. I tend to differentiate them by using the term buffers for anything that can be extracted from a single render process, while a pass requires different scene settings and a separate render process (i.e. The handling of the names isn't the same across all compositing apps, which explains why exrTrader is more complex than it could be.Īs for buffers/ passes: The terminology is quite fluid here. R,G,B for colours, Y for luminance (which Nuke doesn't like at all), A for Alpha (also interpretedet as a mask in Nuke), Z for depth etc. The naming convention is layername.channelname - and a layer can contain multiple channels (which also follow a naming convention, to a degree). The named part is quite important, as that is used to mimic the notion of layers (by using a naming convention) and that in turn is what many compositing apps read as layers from a single file. OpenEXR in a nutshell: It is basically an image file format that allows you to save an unlimited amount of named HDR channels in a single file along with some meta data and optional (lossy or lossless) compression.

‘Out of Focus’ also offers background distortion for semi transparent areas.As a start I suggest having a look at the exrTrader manual since it doesn't only explain exrTrader but also tries to explain the buffers that LW exports as well as the capabilities of exr. It’s possible to use a custom drawn lens in addition to the generateable ones. It offers some extra functionality as well. It creates a blur with constant radius over the complete image and is a good complement to ‘Depth of Field’. Out of Focus ‘Out of Focus’ is a fast version that works without depth information. It needs a depth buffer for its calculations. The depth of field plugin generates those fast as a post process.
In computer graphics dof is usually generated using ray tracing techniques which increase rendering times considerably. It is heavily used in photography and film as a style element. Lenscare is available as plugins for Adobe After Effects and Photoshop compatible programs.Depth of Field Depth of field effects (dof) happen in all real optical devices to a certain extent. The key aspect during the development of these filters was to match the real thing as good as possible. It can get you rid of long extra 3d rendering times. If you need high quality camera blurs with the flexibility of 2d post processing, Lenscare is a great choice.
