Daeberethwen Arbenlow has a 20 minute video (3/27/2016) on controlling your Windlight settings for photography in Second Life. She uses the Firestorm Viewer and the Photo Tools feature it has. Those using the basic Linden viewer can accomplish the same changes to Windlight, just not as easily nor will the video help you learn how to use the Linden viewer, just the Firestorm viewer.
Daeberethwen does a good job of explaining all the settings and what they do. Along with the verbal description is the video example allowing you to see the changes.
Firestorm has the best set of features for photographers and machinigraphers (or is that machinamists?).
For ‘artistic’ photography and machinima the Firestorm viewer is my favorite. I still have problems with the FS viewer going all jerky on me. The PING time goes high, pulls FPS down, and things get jerky. I can ping the sim from the Windows command prompt and the ping time is good. So, it is viewer/server lag.
The FPS is better in this version (4.7.7-48706). I do tend to turn Sun/Moon & Projectors off when using FS. But, I haven’t crashed with FS. About 90 minutes in I get mini freezes and low FPS. But, I haven’t used this version as much as I have the current Catznip and HTTP RC Linden, mostly because they seem to work better.
For a series of quick still shots, I like FS best, click and save, repeat. Several other viewers have a couple of more required clicks in the process slowing things down. Also, some viewers with each new secession require you enter a beginning file name for your shots. I find that handy and prefer it. Others don’t. They just use ‘snapshot’ by default and I have to ‘save as…’ to change the name.
For quick photos and machinima I tend to just shoot from the Linden viewer (HTTP RC for now). It too is jerky but doesn’t seem as jerky as FS. I do crash with the HTTP RC sometime after the first hour of use.
While I find all the viewers currently more problematic than past viewers, when I go back and look at the images I captured from 2008 to 2014, they don’t compare with what I capture now. Second Life is much nicer looking now than it was. With the features in Firestorm your images can be gorgeous.
