Question 1 - from Listener Tom

I use Aperture. I would like to combine two or mor photos into one jpg pr tiff file to make a diptych or triotych without any loss of quality, without any Adobe products. Any suggestions on how to do that? Thanks.

Question 2 - from Listener Ken

Greetings from Vermont. A question came up while looking to upgrade a lens. What is the operating temperature range for a lens? Specifically since it does get cold and I do take the camera (Pentax K-3) out in the cold (zero degrees F). The camera is rated to -10 F but what about the lens. It's not about condensation when coming inside. I contacted Sigma and asked about their 10-20mm F4-F5.6. They came back with a low of 38 F with the comment "it will go beyond for short periods of time". I've check Pentax lenses and the specs do not specify a temperature range. Several Pentax blogs state use well below zero degrees. So I wonder if this might be a good thing to talk about. Many thanks for the show.
