Shooting Lessons pt. III: Shutter Speed

     In my opinion, there are two requirements for a good image/video when it comes to shooting aircraft:  proper shutter speed, and great panning.  In this lesson I will speak about the first, shutter speed.

     First of all, the goal of anybody shooting propeller driven aircraft or helicopters should be to shoot at the slowest shutter speed possible so as to obtain a good amount of prop/rotor blur.  A stationary propeller or rotor makes the subject look like it is just a toy, suspended in the air.  An image with a full-disc of prop/rotor blur makes the picture pop with energy and excitement and more accurately portrays how the human eye sees it

     When shooting propeller-driven aircraft, I suggest shooting absolutely no faster than 1/150 of a second.  When I'm out of practice I will still shoot still photos at 1/125, but when I have been out shooting for days on end, I can handhold my 500mm lens down to 1/50 to get a nice, full, disc of prop blur.  If your shooting jets you can certainly up the shutter speed, but keep in mind, tracking a fast subject with a completely stopped background is not nearly as exciting as one with a tack-sharp subject and a completely motion blurred background.  When shooting jets I tend to keep it around 1/200.  That keeps my autofocus happy, and it provides a nice amount of blur.  Helicopters are the tricky buggers!  Those you absolutely want to shoot as slow as possible, as the main rotor blades move much slower than propellers.  Those you want to shoot under 1/100 second when at all possible.

     While shooting video I am able to get a good amount of propeller blur when I select a shutter speed of 1/100 second.  Sometimes, if I do not have to pan a lot, I will slow it down to 1/60. 

Equipment consideration:  slow shutter speed may make it more difficult for your cameras autofocus to track the subject!  As I hinted above, there are very few times I will slow it down to 1/60 second using my Canon HG20 due to the fact that any slight shaking or movement of the subject will cause the autofocus to get confused.


Enjoy these tips and be sure to comment if you have any questions or need clarification!  Eventually I hope to turn these into video tutorials.

Shooting Lessons pt. II: When in Doubt, Zoom out!!

     Now that I have trained myself to wait for my subject to be closer before recording and follow the previous rules, I have yet another bad habit to fix: zooming in too far. I am not quite sure why it is, but for some reason every time I see an aircraft approaching through my viewfinder/screen I zoom all the way in. Once I get home and see the video I am again disappointed that the video quality is less than what I remember when shooting.  Just like time compression in my previous post (Norm, you know what I'm talking about!).  The plane jumps all around the frame in a blurry mass if metal. Ever been there? Again, taking notes from my still photography, it took me a while to back off when I first got my Sigma 50-500mm lens. I wanted to be able to see the look on the pilots face as they passed by. Several years later that amusement has warn off for better things such as framing. Same should be done with my video. I need to back it off.
     Today, as a matter of fact, I applied this very rule, with very good results.  I can't see the pilots faces, but I can see the entire aircraft and its proximity to the ground.  This, I believe, makes for a much more pleasing clip.  Extreme closeups have their time and place but should be used sparingly.

     Just like in still photography, there is an exception.  Extreme closeups can be very cool, and add a lot of energy to your video.  However, it must be done with great consideration!  Here are some rules that I follow with my still photography and am trying to apply to video.
1.  Make it look intentional!  Clipping just the very end of the nose, tail, or wingtip looks sloppy.  If you want it full frame, zoom out a bit.  If you want it cropped, zoom in so as your viewer knows you are trying to focus on one particular aspect of the aircraft.

2.  Make it look smooth!  At least, as smooth as possible.  You never know if you don't try, right?  Try to find a zoom range that works for you and your equipment and make a mental note for yourself to NEVER go beyond that range.  Make a small mark on your camera if you need to. 

3.  Just like real life pilots, make yourself some personal minimums.  Go practice shooting and determine the amount of zoom that you like for those shots you MUST keep in the future.  But, be sure that when the moment counts, you don't press your luck and assume you'll be "just fine" this time out.  I've ruined too many amazing photo opportunities because of this.  Some photographers will tell you to take the risk, I tend to say err on the conservative side.  I'd rather have a clip that leaves me wanting more, than one that leaves me wanting less.

Equipment Consideration:

Not all image stabilization is created equal, and none are perfect!

Again, consider your focus points.  I know I mentioned this in the last post, but you must be aware of the focus point(s) in the camera you are using.  I cannot tell you how many times I wanted have nice 1/3 framing, only to find my camera kept trying to focus on a blank background, which ruined the shot.  In this case, what I should have done is zoom out more so I can still keep my subject in the center (focus point) and the ground on the bottom portion of the screen.

I hope these tips help in some way, either in shooting video or still photography!  Please comment below and share with your friends!

Blue skies and happy shooting!!
