In Topic: Flash settings with Olympus E-M1

Hi Michael,

 

maybe you want to have a look here. I did some tests with the magnet in/out and TTL/manual:

Generally I think it is not a good idea to mix different strobe brands and try to use TTL; even with two identical Inon Z240 TTL is not reliable - at least in my setup with an E-M5. Maybe the E-M1 is better in that respect? (I doubt...)

 

For wide angle TTL does not make sense, and for macro it is convenient (if it works!), but I shoot manual now. If exposure is a bit too bright or too dark, just use your RAW converter.

p.s. TTL="fill" in the camera and S-TTL on the strobe


In Topic: OM-D E-M5 II stabilization improvement significant?

There is a rule of thumbs for focal length and shutter time: If you shoot with 50mm, use 1/50sec or faster, if you shoot 140mm, use 1/140sec or faster etc. This is WITHOUT I.S. With stabilisation you can use longer shutter times.

You see, for wide angle like the Panasonic 7-14mm you can use relatively long shutter times and still get sharp pics. The advanced I.S. will be good if you shoot birds with a long lens like the Pana 100-300, but for u/w does not matter that much.

In Topic: Any news on the restrictions for 3 Sisters Springs?

Hi,

This link is a re-post from an article on the wetpixel main page, just in case someone will find this thread by the search function:

The Fish And Wildlife Service will annonce the status of Three sisters.

I was in their complex yesterday and watched a video which explains the latest rules for photographers and videographers, here are some key points:
As a "pro" you will need a permit, and you will have to wear a yellow vest.
Flash photography is allowed, you need to use a diffusor. You will have to wait some seconds before you take another flash photo, no rapid firing allowed.
You may submerge, but are not allowed to dive down head first onto a manatee.
And, most important, you will have to keep a distance of six feet to a manatee.

I hope FWS will put that video online, easiest way to avoid confusion and discussion....

In Topic: Metering for OMD-10

Hi ML,

What exposure mode do you use (P/A/M)? Do you use your strobes in TTL mode or manual? What lens? Maybe you can post an example?

If you use A with TTL the exposure is correct without strobes, and the strobes will submit only very little light - your pics are blueish.

If you are too far away from your subjects, the "warm" colours are filtered - your pics are blueish.

Hi,

as Bill said: Shoot RAW! Don't waste your bottom time fumbling at your camera settings - you can do it later when shooting RAW. Are you familiar with this concept? (I know some photographers are not), but this is THE advantage of a digital camera. Plenty of infos available on the net. And don't be afraid, it is not comlicated.
