There are two new filters for Photoshop CS6 (currently for Mac only) that have been posted to Adobe Labs – Interpolate and Match Edge. The Interpolate filter fills the transparent areas of the current layer with a smooth mix of the colors in the opaque areas while the Match Edges filter changes the colors at the edges of the targeted layer to match those of the layer below it, and smoothly distributes this change through the layer. Like other technologies on Adobe Labs, these tools are not finished products, but rather beta or prototype utilities that may work in your particular environment. To download the plug-ins and for more information, please visit Adobe Labs.

There are several new filters that can be applied in Photoshop CS5 via Pixel Bender. Pixel Bender can be downloaded from Adobe Labs and while there are several filters that ship with Pixel Bender by default (I am especially partial to OilPaint), there are additional filters that can be installed from the Pixel Bender Exchange site. I have included just a few samples below. Have fun!

In Camera Raw in Photoshop and in the Develop Module in Lightroom, the lens profile popup will only display the profiles appropriate for the file type. So if you’re looking at a raw file, you get to see raw-based lens profiles. If you’re looking at a jpeg, you get to see non-raw-based lens profiles.
Adobe provides many more raw-based lens profiles, than non-raw-based lens profiles. Unfortunately, lens correction quality for non-raw files (JPEGs, TIFFs, etc.) can be very problematic. This is because it depends on where the JPEG/TIFF came from, and how it was previously processed. For example, a JPEG that comes straight out of the camera is very different from a JPEG that somebody created from a raw file in ACR. If you try to apply the same non-raw-based lens profile to these two cases, you can get quite-different results (even though they’re both JPEGs from the same camera & lens). In other words, correction quality is not very stable.
