Could be a number of reasons. As GAU-8A said, a good lens helps!

Atmospheric conditions on the day could cause haze, a too slow shutter speed may induce camera shake and then, of course, is the masterfully way Mistral does his post-processing/editing.

Hi Mistral.

Those photos are amazing.

How do you get your pics so clear? I struggle to get them like that. I dont have a very fancy camera. Its and old Canon 1100D with the normal EF 75mm-300mm lens. When i take the photos without zoom they are nice and crisp. Problem comes when I zoom in and take them. Then they become fuzzy. Is it something to do with my settings on the camera?


Thanks AM. The most important factor is the quality of your lens. Moreso than the body. However, that said, I recently changed to the 7D Mk II from the MkI and the quality is streets ahead. Very little grain / noise etc.

Image fuzziness can be attributed to three things :
a) Lens quality - throw money at the problem 8) .
b) Heat haze / general haze - if you're zooming more because your subject is further away, you'll be shooting through a thicker layer of atmosphere. Bad on hot, hazy days.
c) Camera shake - this is down to two factors :
1) Your camera speed is too low when you've zoomed in. Typical rule of thumb - your camera speed should never be less than your zoom focal length - so for example, if you're zooming at 300mm focal length you should be shooting at a speed of higher than 1/300th of a second. This is a challenge with prop aircraft / helicopters. You're always wanting to slow down your speed to get propeller / rotor movement - typically maximum shutter speed of 1/320th if not less (there's nothing worse than a photo of a prop aircraft taken at high speed with no prop movement - looks unnatural). That brings us to the next item
2) A steady hand and good panning practice. Practice your panning and depressing the shutter at the same time. Pressing down on the shutter is usually accompanied by unwanted camera movement. Take a deep breath and slowly exhale whilst panning and gently depressing the shutter. 30% of my slow speed shots are actually sharp - the rest get unceremoniously dumped. Place settings on AI Servo and multiple shots. Squeeze off two or three shots, wait a second and then another set of two/three while trying to pan smoothly. Easier said than done.

The guys who get good aerial shots of full prop discs are usually shooting close in (low focal length). Thus camera shake is less of an issue.

Final two notes to consider : understand your lens's "sweet spot" - this is usually within 30 to 70% of the focal length range. Very seldom will you get the same sharpness at 100% zoom than at 75% zoom for any lens expect on a very expensive "prime" lens. At the same time, there'll be a best aperture setting as well - using f8 or F11 should be as safe bet.
Keep your ISO setting down as well (depending on light conditions) - ISO 200 max otherwise you'll be fighting unwanted noise in your post processing software.

Talking about post processing - once you've done all your processing, resize the image to 800pixels (for posting on the web) and sharpen the image at a setting of 75 to 100.

So in summary :
Buy a good lens if you have cash
Then buy a good camera if you have cash left over
Practice panning - the more you practice the better you'll get
Try not to take pictures at maximum zoom - wait for subject to get closer
Set your aperture and zoom for the lens's sweet spot
Pan smoothly
Review images and throw away the out of focus ones - don't keep mediocre images !
Resize image and sharpen

Hope that helps.

And like GAU-8A says, post your pics anyway :smt023

My 2 c's

Lighting is very important to image quality, and the lighting from Blouberg is particularly good. I Immediately noticed this from the images from AFD 2019.

Photo subject prop RPM would also higher.
