Re: Project 52 by Wendy (ScoutR)
here are a couple bad shots to show you what I want to improve on to give you an idea of the conditions.
#1. EXIF: uncropped: 1/400s: f 5.6: ISO 800: +2 1/2 EV: 130mm

FlyingSquirrels-2 by Wendy FS, on Flickr
Off to the left (on screen) there are 2 apple trees and a chestnut tree. The squirrels use the trees as a highway. I'd like to be able to freeze the squirrels in mid jump and still end up with sharp clear pictures where I can see the eyes and whiskers and expression on their faces.
From the perspective of these shots, the squirrels path is usually left to right or right to left. Forward or backwards movement might range up to 5 or 6 feet.
When I saw Dave's post suggesting MF I thought he was joking but he seems like a pretty serious guy and there wasn't a smiley face so it got me thinking (scary)
Anyway, my original thought was that 3D tracking might be best for this, but I think the camera will still have trouble locking on the squirrel and staying locked on with all the tree branches around.
I also started to realize that this is not so much a focus challenge as it is having a fast enough shutter speed and more DOF to compensate for any forward to back movement.
Conclusion: I think you guys might be right and manual focus just might be the answer. I can anticipate to a certain extent where I want to focus. Whether the squirrel ends up there will be a matter of luck, BUT if I have the lens stopped down enough - say f16, I might have enough DOF to keep it in focus. The other consideration is shutter speed, so I will pick a day with good light and then adjust ISO to give me a shutter speed of at least hmm... 1 500s or higher
I'm really perplexed by this. Not so much because I want a shot of squirrels in mid air, but trying to figure out if and how it can be done to get a technically good shot. I`m not worried about composition or background or anything else, I just want to get a good sharp shot. This is a practise exercise more than anything else.
Let me know if I am getting myself sorted out on this. I think I was way off track thinking focus was the main issue. I will keep practising on this one when I get a chance. A good shot is not my goal for this week, BUT I will have something better before years end.

If you can manage it I think you're going to go much faster with your shutter speed. I believe (given that we don't have them down here) squirrels move pretty fast and that you're probably going to need something in the order of at least 1/2000s to have a chance of capturing them frozen and sharp. The diving photos I took were at 1/1000s - couldn't do it any slower than that) and that motion I think is relatively slow and predictable compared to a squirrel's movements. I posted a photo of my eldest doing a jump on his scooter (Project 52 Week 3 Reject) at about 25km/hr and 1/3200s was the slowest shutter speed I could use before I finally got a sharp picture of him in mid flight.

If you zoom in tighter to I think the 3D AF will have more of a chance of tracking the squirrel. If your squirrel is moving backwards and forwards up to 6 feet I think you may struggle to MF. I'm guessing you're at a wider view to compensate for any unexpected movement in the frame. One of the tricks that I learnt in the military for tracking a subject that I've zoomed in on is to keep both eyes open - one through the view finder for composition and the other allows you to see lateral movement easier and react faster than if you were looking through the view finder alone.
Something else to try out in any case. Given the shutter speed I think you need you might not be able to stop down too far.
Oh and I thought I'd add the reason for the higher shutter speed is not just because of your subject's movement, but your own as you track it. If you're moving in one direction and the squirrel suddenly changes direction to go in the opposite way and you snap the shutter the combined effect of the different travels of direction can cause a loss of sharpness.
Re: Project 52 by Wendy (ScoutR)
You know, my first thought was "1/5000s???" But in all honesty it looks great! Your ISO's not extreme - and to be honest is probably set right for a moving animal - the cat could have taken off at any time after all.
Besides, you don't have to use the same old settings to get the light balance right. There's more than one way to skin a cat :D
Week 4 Project 52 by Wendy (ScoutR)
I have decided that from here on in for this project I am not going to tie myself down to a weekly goal. I still have all the goals previously mentioned and more as I think of them, but I am finding that sometimes the opportunity for a particular goal might not present itself that week and it really cramps my style and makes me claustrophobic when I have to commit to one thing. ;)
So right now I don't know what I will be working on this week. I'm not finished with autofocus and I've already learned a few things that work and some that don't, but I don't want to spend all my time looking for moving subjects, so this week might be something different, but I won't know what it is until I see or read about it. It'll be a surprise. :)
Now I'm off to check out everyone Else's projects which I have not had time to do all week. I hope I don't get called away before I am finished. :(

Re: Project 52 by Wendy (ScoutR)
I think its a great photo ;) Wish we had snow - especially right now, as I'm sitting sweltering in a hot lounge room after my afternoon Xbox workout LOL.
Re: Project 52 by Wendy (ScoutR)
Nice one. So if you feed it and it walks around with you, is it still a feral or is it now you pet?
Re: Project 52 by Wendy (ScoutR)
The footprints in the snow are beautiful. This, again, shows how the good images are very often the simple ones. A cat; Its shadow; Snow; Footprints. That's all it needs.
Can I jump (pun intended) back to the leaping squirrels?
If I missed the following being noted, I apologise. But it seems to me that you are able to predict with a high degree of accuracy, the route the squirrel will take. In which case you can manually pre-focus on a mid-air point on that route. Set yourself up for burst shooting with a high shutter speed. And when a squirrel starts on the move, start firing the shutter.
It may take a few attempts, but you'll nail it in one of them.
As I say, apologies of this was discussed above and I missed it, or it was previously dismissed as an idea.

EXIF: 1/5000s: f5.6: ISO 800: 44mm: Matrix +2/3 EV: AFC 9 point
Why oh why did I not stop down a bit on this one OR lower ISO???? I'm sure I didn't need 1/5000s shutter speed. My excuse is that I was out tracking squirrels and birds. The cat shot was an afterthought. By the time I get finished with project 52 I will know this camera well enough and have things set up so I think fast enough and make the changes automatically. That's my goal anyway.

Lovely photo and lovely cat!:)
perhaps, an other thing that could improve this one is a lower point of view: next time, while you are changing the ISo / shutter / aperture settings you could bend down on your knees... :rolleyes:;):)

Re: Project 52 by Wendy (ScoutR)
Well it's only been 4 weeks and already I am way behind on projects and replies and everything else it seems. The last 2 weeks have been exceptionally busy.
Thanks for all the feedback since I last checked in. I didn't notice that there were more posts or I would have answered sooner. My apologies.
Donald, I think you are right about the squirrels, but I know I will have to sit there quite awhile until they take the usual route with me sitting as close as I'd like to be. They run and jump from tree to tree all year round though so I know I'll get the shot before the year is over. :)
Sam, The cat is still feral, she is just training me to make sure I like her well enough to bring her food on time. She seems to like being petted, but I think it just helps warm her up. At least she warns me before she attacks. Then I leave her alone.
Nicola, LOL, by the end of the year I might be able to do all those things on the fly. Not sure I would have liked the low angle on this one though, I don't think the footprints would have shown up as well and they are as important as the cat and the shadow. I know what you mean though, about getting down to the subjects level. In most cases I would try to do that.

Re: Project 52 by Wendy (ScoutR): Week 4
I know where you're coming from with print sizes. I've found that with some of the family and portrait shots I've done when it comes to getting them printed, I need to pay more attention to how I do the cropping of shots.
A nice fun shot you've come up with this week :) Trying to get moving birds sharply is always a challenge!
