Bottom line here that everyone needs to consider is that the sun sets to the west and the Riviera Maya (most places) face due east.
If you DONT get married during daylight savings time, if you start your ceremony at 3pm-4pm, someone (usually always the bride or the person standing on the left) will be blinded by the sun's harsh beams of light.
This is a fact, no disputing this unless you are getting married under a covered area.
Harsh beams of light make for the hardest to photograph in relationship to contrast. Squinting eyes and just harsh light...
We recommend 4-4:30 ceremony start time if you don't get married during daylight savings. I've seen hundreds of weddings on the RM coast, and LOTS of them starting at 3 or 3:30... blasting the poor eyes out of the bride.
Check out this slideshow to get an idea of what I'm talking about...this was a JAN wedding:
The light is harsh, contrasty and slightly painful for bride and bridesmaids to stare at... Shot in Playa del Carmen.
Here is another non-daylight savings wedding |January 1/19/08 wedding
Either way, we think some of the best light in the sky happens AFTER the sun sets. If you have super nice equipment (fast lenses) then you can shoot well into the early evening.
We shot this wedding in tulum this year... ceremony started real late after 6pm... , bride and groom walk down the isle at 6:27pm!
Last picture we shot on the beach is actually moon lit, shot at 6:54pm.
Pretty insane eh?
Notice the quality of light during the ceremony..
Here is their slideshow: del Sol Photography Wedding Photojournalism
| Shot in Tulum. We don't actually recommend ceremonies to start this late as we won't have time to shoot any formals / b&g portraits post ceremomy, but this just goes to show you the maximum of our camera's abilities very late in the evening!
We use very fast pro lenses, so we can shoot with very low light situations...another advantage by hiring a pro photog! You may want to ask your photographer... but you can trust that later is better than earlier for us
If you are considering a Daylight savings wedding, try around 5 or 5:30 ceremony start time.
hope that helps put some photo perspective to your question!
