Recently acquired this speed light so I never shot with it.I do not have the manual.
I am no longer in business so I would have to dig through hard drives to pull some images up.
My history with flashes goes back to my first a Multiblitz Report then to Ascor 444 candid
then to Norman 2OOb's added to the Norman the General Varionics head that turned the flash into a auto flash
Along the way I had some Ascor 1600 potatoe masher type of strobes then went to Lumedyne also with the General Varionics auto head. Then Quatum developed there Q flash heads and I went to them for the Lumedynes.
Studio strobes were at first Balcar then Dynalite all the way. This was all used with my Hasselblad system.
When I went to Nikon digital I used Sb-800's. In the beginning the flash's were triggered by optical slaves.
Then to Dynalite radio slaves then to Venca radios and finally to pocket wizards.
I have many of Dynalites and Sb-800s available for purchase. I also have pocket wizards available for purchase.
This should help a little with my history.
Thank you for reading.

This is a non dedicated manual flash and as such will work with any hot shoe enabled camera.
The YN 560IV speedlight took the 560III and introduced a built in controller as well. Now you can have it all in one nice package. Complete wireless radio signal control is built into the speedlight. Using this as a master flash you can control up to 3 groups of speedlights, 560iii or 560iv. You can make all the adjustment to the power output from this speedlight and it will send the information to the ones that you are using off camera. No need to walk over to make those adjustments.. Portrait photographers, Real Estate photographers and more love this speedlight for its ease of use and its tremendous light output.Speedlite for Canon Nikon Pentax Olympus DSLR Cameras

Typically using oem equipment would be best.
Not in this case. Firstly the 910 was not known to be the best flash. Although Nikon manufactured decent flash
their business is cameras.
On the other hand Pro Photo arguably makes some of the best flash equipment available.
The A10 far and away blows away all competition. Yes it is more expensive but worth every penny.
If you have the funds do not hesitate. Use the 910 as backup and enjoy a very fine flash.

That was the fact years ago. Go PPA or any other photo conventions and you will see them predominately populated by women.

Look at the shadows. The shadow from her arm, the shadow under her body. The technology to be recreate these as perfect as they are did not exist at the time this was taken. I say right out of the camera.
The bulbs where her bottom is we're removed so she could sit. The model probably was an aerialist used to heights.

After being in the Wedding photo industry for over 40 years I can comment with some authority.
People pay for images to choose from. When their choices are made they are charged accordingly.
By processing all of the images you give the client free reign to print whatever and as many as they want without charge. Seven months is not uncommon for delivery. Many times the client procrastinates giving the photographer their choices for weeks or sometimes months. You cannot start to work if you do not know what to print. So you have the choices you do all the needed processing- then you do the album design- then you send out for the prints-then you proof the prints-generally there might be a couple of remakes so now you need to order new prints and lastly if you are a high quality photo studio you are making custom leather bound albums that are sent out to be made. Add all the time in involved including shipping and it adds up. And I forgot with many of my clients I did a print review before binding because changing a print in a bound book is a royal pain. Photographers do their job because they love it- But they also need to be compensated for their time. Nobody works a 40 hour week and gets paid for 20 hours.

The zone system is not that hard to grasp. Yes you may have reread things a few times. But the zone system can be explained using the black to white zone chart. The concept of correcting the internal camera meter is very important. For a newbie or some not so newbies.
Exposure compensation is simply a way to add a plus or minus to your meter's exposure reading when you are in a s or p modes. In manual mode you would do that on the fly disregarding what your meter shows.

Actually what you are all talking about is Ansel Adams invention of the Zone system.
Google how the zone system works and the theory of 18% grey will be explained.
This system works with reflected light meters as those in cameras. It does not apply to incident meters.
Incident meters measure the actual light with no internal compensation for 18% or middle grey.
This is why you would put a grey card into your scene and read from that eliminating reflectivity issues.
Just my two cents.

Good afternoon,
I very rarely post, but in regard to the question of rear mount filters they are used primarily on extreme wide angles such as the Nikon 14-24. There is a company called Aurora aperture that has just started a kickstarter
campaign for their next generation of rear mount filters for certain very wide angle lenses. System looks very nice. You should check them out.
Thank you and stay safe.
