DSC05190: Looking Through...


DSC05190: Looking Through..., originally uploaded by RMStringer.

While on vacation in Texas for Christmas, we were at my Grandparents home on Lake Sam Rayburn. This photo is looking at the cove where you can park your boat during the summer. At the moment, the lake is very low and the cove is dry.

I had some very, very fun times on this lake during the many summers that i spent there! This is a much different looking photo than what you would see during the summer. It is a bleak, dull looking gray photo with no life. During the summer, it is a bright green "parkway" that allows you 24 hour access to the water and your boat. There are houses to the left and the right but none on this area...

At this moment in time, this photo is a dim reminder of the Winter season that we are all in but don't fret, Spring and Summer are right around the corner.

ADI Flash Vs. TTL Flash

I saw this question posed on the Sony Alpha DSLR-A200 flickr group.

What is the difference between ADI Flash and TTL flash. I found a few articles on the subject.

Maxxum 7 TTL flash vs ADI flash system


"The ADI system helps when you have a reflective surface in the background. If you were to take a picture of someone in front of a window and you focused on the person, you might get a big reflection of the flash from the glass which would cause the camera to reduce the output of the flash leading to an under-exposure of the main subject. With ADI, the camera knows that you are focused on the person and will disregard the reflection from the glass. "

he pre-flash utelises the 'normal' 14 segment meter to evaluate the correct exposure rather than the 4 segment dedicated TTL flash meter. In theory this should produce more accuarate results. The ADI system gives extra feedback to help correct problems caused by excessively reflective surfaces in the picture.

By knowing the distance to subject, it is possible for the ADI sytem to calculate the correct flash output on its own but for some reason this only occurs when using the built-in flash. When using an accessory flash, the ADI is always used in conjunction with pre-flash.

Having said that, turning HSS off, setting bounce flash, using off-camera flash, rear curtain flash, multiple flashes or mirror lock-up cancels the ADI/Pre-flash and the whole thing reverts to TTL metering anyway.

So, if you use your flash as the main light source, on-camera, pointing straight at the subject, in conditions that may confuse the exposure system, then ADI can be useful as it 'throws a little extra into the mix' when the camera calculates the correct flash output.'


If someone out there in cyberspace can add something to this i would sure be appreciative of it. My new F58AM Sony flash came in and i have wondered the same thing.
