A few months ago I started testing some of Topaz Labs products using the 30 day trial offers. I particularly like ‘Impression’ but until recently I had been very frustrated by not being able to access Topaz Impression directly from Lightroom.
Because I really like the software I persevered for many weeks and was in constant touch with Topaz support who were most helpful. However, they too were unable to fathom out the problem and the conclusion I came to at the time was that it could only be used as a ‘stand-alone’.
But, as often happens, my subconscious continued working and in a light bulb moment it became obvious that we had been barking up the wrong tree. Topaz products work via Topaz ‘Fusion Express’, which has to be installed in Lightroom before it can access the plug-ins. But ‘Impression’ doesn’t work through ‘Fusion Express’ like the other Topaz plug-ins do.
So in order to avoid exiting Lightroom to use ‘Impression’ you have to add ‘Impression’ as a pre-set.
Then you can access Topaz Impression directly from Lightroom (but not via ‘Fusion Express’). Then your processed image will be returned automatically to Lightroom as it is with other Topaz products.
To link ‘Impression’ as a pre-set, on PC, this is what you have to do.
After Installing ‘Impression’ open Lightroom:
Go to Edit>Preferences> Additional external editor> Choose
Find ‘timpression.exe’ (Program Files>Topaz Labs>Topaz Impression) and click OPEN. You will see it appear next to Application: timpression.exe
In the Preset box type ‘Topaz Impression’.
File Format: TIFF
Color Space: ProPhoto RGB
Bit Depth: 16 bits/component
When you want to use ‘Impression’ first select the photo in the Develop module.
Then go to Photo>Edit In and choose ‘Impression’ as the pre-set you want to work in.
You can add any processing software to Lightroom (Additional external editor) in this way by saving it as a pre-set as described above.
