In Topic: Fish eye or rectilinear for filming?

Today, 01:44 AM

Cal, the 16-35 f4 is definitely the lens to get if you can afford it.  It also has IS which works with video.  17-40 is problematic with corners. especially on the wide end.

As mentioned by others, rectilinear has always been the classic preference for most underwater shooters because of the lack of distortion, especially on moving shots with a busy background.  But even rectilinear wide angle will have some distortion if you pan.  20-24mm is about my favorite focal lengths for underwater use.

In Topic: Softbox vs. diffuser for YS-D1's

Have you tried testing the output of the strobes topside at various levels to see if they are faulty?  The DS1s did have some issues with recalls and such.

Looking at your pics and if you say you had the strobes at ½ and ¾ power, then they can't be working right, assuming you used the correct lighting technique.  The pic of the lady seems to indicate your strobes were pointed up.

As an aside, the 5D3 flash sync speed is really 1 / 200.  In manual, you can go above but you will get a slight band at the bottom of the pic and also catch less light.

I just reread your initial post.  You haven't compensated for the extra power of the DS1.  The DS1 is just under 1.5 stops more powerful than the YS110.  That would be your reason for overexposure.  


my ISO, f-stop, etc. have stayed pretty consistent with both strobes so no issue there.



As for the anemic power, I suspect one strobe is cycling slower than the other, because of the higher setting.  I'll have to see your images to confirm that.

How are you shooting with the new strobes?  Using TTL or manual?  It would help more if you gave more details on how you got your inconsistent results.  It's often technique/settings.

I'll second the recommendation of the H20 Tools carbon arms.   I've used them for 4+ years and they are still going strong.  Travelled over 300k miles in cargo hold and hundreds of dives in demanding conditions and other than nicks in the CF veneer, it's been great!
Comes in various lengths and buoyancy.
