Anchorage Glacier Paddle Boarding

Hello! So I’m very interested in signing up for the glacier paddle boarding tour found near Anchorage and would be planning for mid August. I’ve looked into what time is the best for pictures and videos and I’ve seen some sources say either earlier in the morning (8-11AM) or later in the day (3-7PM). Now I figure right in the afternoon around 12 would be best just due to the sun exposure and lighting and apparently that’s the worst? I figure it would be better for me to come here and ask to gain a better consensus
