You can download GeForce Experience to record and capture videos. However, I think you must have an NVIDIA card installed. You can find the download here: https://www.nvidia.com/en-us/geforce/geforce-experience/

"Alt z" will bring up the program once it's installed.

Sounds interesting. Do you have an URL for the app?

Here's a good article from Nikon regarding their Auto FP Sync feature that explains why you might want to consider using outdoor flash.

I also copied some info from the internet several years ago that was very useful when I had my SB800 flash and D200. I do not have the link to the info but here it is:
Auto FP flash
1. With both the camera and flash OFF, mount othe flash on the camera hot shoe.
2. Turn on both the flash and the camera (order doesn't matter).
3. Go to menu e1 on the camera and select 1/250 s (Auto FP) or 1/320th (Auto FP). Hit 'enter' to save it.
4. 'Wake up' the flash if it is in STBY by half-pressing the shutter button. Then, on the flash press the 'Mode' button several times to cycle through all the modes. You should see 'TTL FP' and maybe 'TTL BL FP' amoung the modes. If 'TTL BL FP' is not shown, you probably have your camera in 'Spot' metering mode. Switch it to 'Matrix' to allow BL. Set the flash in 'TTL FP BL' mode for fill flash testing.
5. On the camera select Manual mode and verify you can set the shutter at speeds above 1/250, all the way up to 1/8000.
Now, you should be able to select camera A mode and shoot in bright light with fill flash.However, the higher the shutter speed you select, the less flash power you will have.

When stopping action is not the goal, and a really high shutter speed is not required, then FP Sync can be very useful. In fact, Auto FP is excellent for shooting portraits in bright daylight. Then, you can use a shutter speed well above the normal sync of 1/250th coupled with a wide aperture to blur the background which greatly helps isolate the subject. I typically use camera A mode, ISO 100, FP Sync, f/ 2.8 and 1/1000th in bright shade, and I get a flash range of about 10-15 feet. If I am in really bright light, like on the beach, the shutter has to be around 1/1600th, and this reduces the range to about 8-10 feet which is still reasonable for portraits. If a greater distance than 10 feet is needed in bright daylight, there is no choice except to use regular flash sync and accept the requisite smaller aperture. This happens frequently when shooting a party outdoors, where I typically shoot in camera S mode, regular flash sync, ISO 100, 1/250th, and f/7, and I get acceptable fill out to 20 to 30 feet or so.

I do what Bill suggested and it works for me everytime.

Who makes it?

I'll take the 32GB card. What payment do you prefer?

This is how I felt when I had to return the new Nikon D5 I bought last year.

You need to go to the shoe forum for that one.

You might want to review your price on the monopod.

Maybe you should see Steve Perry's "The Cropping Epidemic" so that you can decide for yourself.

Bill, you can cut and paste the downloaded picture at this site http://metapicz.com/#landing
and it will give you the metadata.

Here's a link the manual. Good luck!

Another one of those "too good to be true?"
