We had what looks to be a juvenile Cooper's Hawk land at our bird bath. The video is from my phone and isn't great, but the stills I took with my DSLR.

Video #2: biggest, chalk-eating drawing yet! (This time I turned off auto-focus so that the camera didn't try to re-focus every time I moved my arm.)

For the exposure settings: quite a bit was just trial-and-error.  It seemed that the sharpness improved as the aperture closed down: I assume due to the point-source of light.  There's probably a more optimal set of settings than this.  The 6400 was necessary to pick up enough light, but it introduces noise artifacts.

Hooking up the camera to my computer and triggering it remotely helped a lot in reducing the motion blur from vibration, and having a faster shutter speed was necessary to counteract the simple fact that the earth is continuously moving.  It's pretty amazing how quickly the subject will move out of frame.

The lens is my mom's Tamron 200-500mm zoom.  It's a bit special-purpose, but fun to try out.

An elaborate "Hobbit" themed airline safety video from Air New Zealand. Pretty funny.

Wow I'm impressed too.  Your fingers must be worn down from all that blending.

Lighting is far more important in photography than having a fancy camera.  I took this photo using just a modern pocket-sized point-and-shoot digital camera and a light stand + umbrella.  I thought the results turned out quite nice.

Many flashes have support for remote optical synchronization: when the flash on the camera fires, a light sensor in the flash unit detects it and fires itself synchronously.  This is what I used to take this photo.

The key to setting up such a shot is taking advantage of the manual mode on the camera and remote flash.  For instance, most pocket-sized Canon PowerShot cameras have an option to specify the in-camera flash power output manually.  I don't actually want the in-camera flash to expose the scene, so I set it to its lowest available power.  I then guess at some exposure setting that might turn out OK for my off-camera flash (ISO 200, 1/125s, f/5.6), but will be woefully underexposed without it.  I just need the built-in flash to trigger the off-camera one.

Next, I just set up the flash at a reasonable distance to the subject, also set to low power (e.g. 1/64).  I take a test shot, and if it's too bright or too dark, I just add/remove power from the flash, or possibly increase/decrease the amount of light that can enter the lens by adjusting the aperture setting (f-stop).

It looks more complicated than it really is.  Mainly you'd just need to experiment some (too dark? add flash power or move flash closer, and vice versa).

For $70, one can pick up a flash umbrella stand kit like this one.  Flashes run the full price/performance gamut, but if you wanted something that's a reasonable, a $90 Vivitar DF-293 is probably a reasonable bet (5 manual power settings).  I don't have any experience with that particular model, though.  Looking for a used remote flash at a camera store is probably a better option, as the salesperson can help you find one for your needs.

I see what you did there. :D

Smells like a business opportunity to me!

The moon through my mom's 500mm telephoto lens (heavily cropped).  And yes, the earth does move the moon continuously out of your frame.
