I hate movies with cryptic titles.
Does anyone know what the movie "Snakes on a plane" is about?
who knows? anyone go & see it?

Evening all.
It cold outside.
How do I know this?
Just had to re-float my concrete because the bl**dy cats have been having a dance on it

Coupled with this late re-floating and the fact that the concrete was almost 2 hours late, means I will be finish trowling it about 10 tonight, when it will be even bl**dy colder outside.
How has everyone elses day been?

and here we were thinking you had an ideal day to lay concrete. Do you not have an slug gun? In the good old days [I remember...] one could get away with building "cracker guns" in school metalworking classes. You have access to acetelyne yes? use your imagination man!

ok, serious photography question but I'll put it here for #@&*'s and giggles.
struggling to understand flash sync on my 40D. i know what it is and how it works basically. What I don't get is how it gets its speed. The manual says my 40D has a max flash sync speed of 1/250. I don't think I have ever got more than 1/200 and even when I get 1/200 sometimes it has the start of the unsyncing (black vignette along the bottom) Now I really want to get this sorted and know what to expect as a huge amount of my photography as most of you know is using off camera flash.
Why can't I get 1/250 constantly like the manual says?
Why sometimes to I have to drop to 1/160 to avoid syncing artifacts? (this is rare but does happen and has ruined a few good photos as its only noticeable on pc screen)
Chocolate fish and mucho appreciation to the best answer

need to understand what flash & how you're using it before coming up with an answer. Pictures with exif would be good too.
Chocolate fish already removed from #1 son's bathwater (ewww!) so we don't really need more, but thanks for the thought...
some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:
