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.

Mack: A Man's Not Dressed Without His Pocket Knife

 

Thanks to Mack Hall for letting me publish this.

 

A Man's Not Dressed Without His Pocket Knife

 

This last Christmas certain environmentalist groups advertised meaningful green gifts – instead of giving your child a bicycle or a football for Christmas you could donate the money you would have spent on your own kid to some stranger who's shown you a picture of a polar bear allegedly drowning.

 

It's a polar bear, citizens; it swims in the water and eats harp seals, you know, the cute widdy-biddy harp seals with the big ol' eyes.  The polar bear rips screaming baby harp seals apart with its fangs and claws, and the baby harp seals die far more horribly than if they got whacked in the back of the head, and then they get eaten.  How's that for a bedtime story, PETA? 

 

When I was a child there was nothing I would have wanted more than to stumble sleepily but excitedly into the living room to find a card (printed on recycled paper with recycled soy-based ink) giving me glad tidings that a penguin had the new cap pistol I wanted.  Sadly, my parents weren't green, and so gave me cap pistols and baseball gloves and toy trains and an ant farm.

 

Although not as exciting as a new bicycle, a good pocket knife is a far better gift than being bullied into pretending to feel good about a fish or a ground squirrel.  Giving a boy his first pocket knife is a traditional rite of passage, and having it taken away a day or two later for misuse is another traditional rite of passage.  A knife, after all, is a tool, not a toy, and owning one is a grown-up thing.

 

My ol' daddy said that a man's not fully dressed without his pocket knife; experience demonstrates that this is true.  The knife was perhaps the first tool used by humans, probably beginning with a sharp flint, and necessary for skinning a rabbit, slicing veggies, building a fire, eating, building, mending, opening, slicing, dicing, picking your teeth, and cleaning your fingernails.  Mind the order of usage, of course!  No one who lives close to the land or the sea or the workshop can function without a good knife to hand at all times.

 

Thomas Jefferson is often credited for inventing the first folding knife, which, while not as strong as a one-piece, is certainly easier to carry about.  Manufacturers began adding extra blades, and then the Swiss got the idea of adding specific tools in miniature, resulting in the Swiss Army Knife.  Where or not the Swiss Army carries Swiss Army Knives is a good topic of conversation. While these gadgets are fun, I'll bet your old grandpa could accomplish with his single-bladed pocket knife whatever task was necessary before you could find and unlimber the designated thingie out of a Swiss Army Knife or a multi-tool.

 

A friend gave me a nice little lock-back with a single blade with saw-teeth.  I found this knife so useful that a few weeks later I bought a larger model, made-in-America, even while thinking to myself that the last thing I needed was another pocket knife.  And then a few weeks after that Hurricane Rita did not hit New Orleans, and that big ol' American knife with its one large blade and saw-teeth paid for itself many times over with its survival utility.

 

Shiny things under the tree or for a birthday are fun: little plastic boxes that light up and make noise, and other little boxes that allow you to hear The Immortal Words of Our Time – "Can you hear me now?" and "She all up in my face!"  But when you are long-gone, your grandchildren and great-grandchildren will not treasure your MePod or your cell 'phone or your Brickberry, because those dinky disposables will have long since been recycled into beer cans or Chinese cars.  But they will treasure your old pocket knife, its edge well-worn from good, honest use and from many sharpenings around a winter's fire when the stories are told.

 

Sturdy, American-made pocket knives are great, traditional gifts for men and boys.  They are also perfect for skinning baby harp seals.

I wonder what the story is about this tractor? To me, it looks like it was driven to this spot and that is where it stated. It really did not look in that bad of shape, but there must be something wrong with it to be left out like this. It is strange how the grass and brush is only growing in some places around it but not others. Will it rust like so many of the other items on this piece of land?

This was a neat old barn on the property today. The barn's rood had totally fallen in and collapsed to the floor.I love the perspective that i used to take this photo. I was using the 18-70mm Kit Lens that came with the camera due to the wide angle that i could get with it. It was a gloomy, cold day taking the photos today.

I went out today with Todd Shaak and we went to a very old house that is falling down. There were lots of neat old things to shoot all over the property. This old truck was just one of many items to shoot.

I decided to use the 18-70mm lens so i could get better angles than if i had used the 50mm lens. It was about 40 degrees and very cold with lots of fog in the area.

New Flash

Sony HVL-F58AM High-Power Digital Camera Flash with Wireless Ratio Control and Quick Shift Bounce for Sony Alpha Digital SLR
From the Sony website.

The HVL-F58AM flash unit delivers flexible lighting control for α (alpha) DSLR photographers. The innovative new Quick Shift Bounce system allows the flash to pivot 90 degrees left and right to maintain a proper lighting position, even when shooting vertically. The HVL-F58AM can also wirelessly control up to three groups of flashes, and Wireless Ratio Control allows you to specify luminosity ratios for each group. Additionally, the HVL-F58AM features an effective range of more than 45 feet (14.5m) and a fast, five-second recharge time. A built-in wide panel and bounce sheet provide an even greater degree of creative control.

The HVL-F58AM Flash Unit is designed specifically for Sony® α (alpha) DSLR cameras.

Delivers high-illumination output in a compact, lightweight body, with an effective range of more than 45 feet (14.5m) and guide number 58. (Guide number measures the illumination capability of the flash; the higher the number, the higher the light output. Tested at ISO100, 105mm).

The innovative “Quick Shift Bounce” system allows the HVL-F58AM to orbit 90 degrees left and right, allowing you to maintain horizontal light distribution even when shooting vertically. In addition to pivoting side-to-side, the flash unit can also tilt down 10 degrees or back 150 degrees, ensuring customers the lighting freedom they need to capture that perfect shot.

Wireless Ratio Control allows customers to wirelessly control up to three groups of flashes, as well as specify the luminosity ratio for each group, so they can enjoy multiple-flash lighting techniques without the need for special equipment or tedious exposure settings.

The HVL-F58AM Flash Unit recharges approximately 55% faster than the previous Sony® high-end accessory flash (HVL-F56AM), so customers will be ready to catch the next great moment. And because it features a quiet recycle charge, there’s no whine to distract them from their subject.

Auto White Balance compensation allows for more accurate white balance in flash photography sending color temperature information from the HVL-F58AM to the camera, where it is incorporated into the camera’s white balance settings.

Modeling light capability allows the HVL-F58AM to pulse, helping photographers determine where shadows will fall before taking the picture, so they can alter lighting or subject positioning as necessary.

Stroboscopic lighting control lets the HVL-F58AM fire multiple times during a single exposure, allowing customers to capture stroboscopic images where moving subjects are frozen several times in the frame.

ADI (Advanced Distance Integration) metering enables the HVL-F58AM to work more effectively with lenses equipped with distance encoders -- combining TTL (through-the-lens) flash metering with guide number control calculated automatically according to the distance to the subject, the ambient light and the pre-flash reflectivity of the subject.

Conventional flashes only work well at shutter speeds from 1/125 to 1/250 of a second. The Sony® HVL-F58AM Flash Unit provides High-Speed Synchronization mode that enables flash sync with shutter speeds from 1/500 to 1/4000 of a second to catch fast-moving subjects.

The HVL-F58AM automatically adjusts flash for focal-length settings from 24mm to 105mm -- and a built-in, slide-out wide-angle panel increases wide-angle coverage to 16mm.

The HVL-F58AM features a slide-out bounce sheet built into the flash head, and can be used in portraits and other bounced light shots to direct light at a subject’s pupils to deliver more lively expression.

The large, easy-to-see LCD display and intuitive button layout make it easy to configure the HVL-F58AM for a variety of shooting needs.

The HVL-F58AM comes with a mini-stand that can stand on its own or be mounted to a tripod or lighting stand for increased wireless freedom. Folds up for easy storage.

Third Team All American.

Jasper's Sean Weatherspoon named Third Team All American

As found in the KJAS.COM article. This is the radio station in Jasper 107.3fm

Former Jasper Bulldog and current Missouri Tiger Sean Weatherspoon has been named Third Team All American in football by the sports writers of the Associated Press.


Weatherspoon, who graduated from Jasper in 2006, was a member of the Bulldog football team that played Gilmer in the 2004 class 3-A State Championship. Weatherspoon and his Jasper teammates fell just short of the state title in a 47-49 loss to Gilmer. However, many said it was one of the best high school football games ever played in Texas.

Weatherspoon took his talent to the University of Missouri in 2006 and is now a junior. At Missouri, Weatherspoon has been credited with 3 interceptions, 138 tackles, and four quarterback sacks.

Weatherspoon will be in action again this year in his home state on December 29th when Missouri meets Northwestern in the Alamo Bowl in San Antonio's Alamodome.

The game will be broadcast at 7:00 PM on ESPN.

In August, Sean Weatherspoon (left) and two of his Missouri teammates graced the cover of Sports Illustrated.





His father was a teacher of mine when i lived in Jasper Texas. I attended
grades 8-12 there from 1984-1989.
