Also, if you look at the light trail there isn't any way it could be real. Motorcycles have to obey the laws of physics while they are breaking traffic laws and I doubt very much there is a motorcycle in existence that can instantly stop all forward momentum, move at a 90 degree angle from its previous vector while maintaining the original heading, then instantly regain all of its previous forward momentum.

Which just makes me wonder what story the image is trying to tell. Motorbikes are nimble? They're faster? Traffic jams suck?

What I'd guess happened is someone was photographing a traffic jam one night, noticed a motorcyle weaving between cars, but the resulting image or images didn't look right.. lights cut through cars or the line wasn't smooth enough.

So they took an image with just cars and copied in streaks from other images to finish the look.

What are the best weather conditions to get those lovely misty mornings that always seem to make awesome photos? I've been forcing myself to get up at 5:30 the past few days so I can meet the sunrise, and haven't seen any mists.

Do I need fresh rainfall? Is it a temperature thing? Air pressure? Combination of the three?

There's no shortage of dew out there.. I come back with my pants soaked, but I'm not seeing any mist.

If the camera can't achieve autofocus, it won't let you take a picture. The camera requires some contrast in the scene to do this, so if you're taking picture of a night sky.. the camera is probably going to make a token effort at finding focus, then quickly give up (which it does silently, giving no hint there's an issue).

The lens should have a AF/M switch on it to put it in manual focus. The "M" setting on the mode dial just tells the camera you want to set shutter/aperture manually.. doesn't effect focus at all.

Yeah.. if the moon is still out, you can use it to focus.

A much cheaper solution is to take pictures of things you normally don't.

Or just take a break. Pause for two weeks, when you pick the camera up again suddenly everything will seem interesting.

You can do stereoscopic with careful camera control.. take a picture, move your body a few inches to the side, take a second picture.

A slightly better way is two identical cameras with identical lenses, mount them on a bar (you can buy such rigs) and release the shutter at the same time.

The expensive way is buying a stereoscopic camera.

But really, who's got info on how to get started on stereo images? I'm particularly confused when it comes to viewing them.

Look up software on making red/cyan anaglyphs. That's the crappiest and cheapest 3D.

Or you can take two images, scale them down a bunch, and put them side by side. Then you do the cross-eyed thing to make a 3D illusion.

Anything beyond that requires real money. Polarizing 3D needs a special display, and there's the old style where there's a special viewer that uses mirrors to direct a different image to each eye.

I want to know why flickr forces me to switch to the black background slideshow view before I can get to the high resolution version. Which I click a magnifying glass, it should give me a bigger image, no questions asked.

It seems to me the site only survives because it's popular.. the interface is lovely and the community is even worse. But it got that critical mass and has become too big to fail.

Picasa gives 1GB for free, bumping up to 20GB is $5 a year. Their maximum is 16TB, for $4,000 a year.

I've been pretty content with it, their photo editing program isn't the coolest thing in the world but it works for managing your online folders.

Officially, most airlines state you're allowed a single carry-on, they don't care about the contents. In practice they seem to not mind as long as your stuff fits under the seat in front of you. They get a little more pissy during the holidays because everyone is trying to bend the rules.

The only way they can achieve the assumed goal of "100% safety" is to force people to fly completely naked (following a cavity search) and with no luggage. I'd be surprised if there isn't some risk analysis report hidden in the depths of the TSA that admits this.

Just do the same thing that musicians do with their instruments.. when bringing your guitar in from the cold, set the case down and don't open it. Let it sit for 40 minutes so it can gradually get up to room temperature. After 20 minutes you can crack the case to help it along.

It's the sudden change from cold to warm that causes condensation (or cracking the finish, in the case of a guitar), so if you remove that, everything will be fine.

You can't create information out of what isn't there, this just looks like some kind of modified Smart Sharpen + contrast.

The license plate test was pretty interesting though. If the program understands the path the camera took while the shutter was open (like if someone bumped the tripod), it seems within the realm of possibility that the program could figure out which pixels should go where.

Of course, but the research is still interesting. It could be adapted for use on things more interesting than fixing a lovely snapshot.. restoring old photos, improving the quality of security footage, finding out who really killed JFK, whatever.

I'm not saying they'll be doing Blade Runner style enhancement, but improving the quality of the data that is there is a pretty interesting topic.

I've taken to hauling my camera bag everywhere I go. Too many times I've been out driving, come across a neat scene or some cool light, and not had the camera with me.

I keep the bag pretty light so it's not too painful to lug around constantly. Can't say it's improved my pictures much but at least I can't blame not having a camera.. I can only blame my lack of skills.

Exposure time is the number you're after.

Half a second on a moving subject (or a bumped camera) could definitely create that kind of blur.

It's not so much the filesystem that's at fault as it is the underlying mechanics that allow flash memory to work. It benefits greatly from occasional formatting to reset everything to a known state.

I've heard dudes at camera stores lecturing customers on this several times.. confused lady wondering why the pictures of her kids came out garbled, he asks how often the SD card is formatted. When she answers "never", he tells her to format the card every time she copies pictures to the computer.

Yes it's anecdotal but I've overhead this conversation enough to conclude that basically everyone "in the know" formats their cards regularly.

I took my camera out on a walk the other day.. it was a balmy 5 degreees (fahrenheit), and the camera was fine.

Towards the end of the walk however, it sounded like the focus mechanism was straining a bit. When I switched to manual focus everything was rotating freely, so I think it was mostly the battery getting too cold to deliver enough juice to properly power the lens (IS and AF) as well as the camera.

Maybe a battery grip would have fewer issues? Not sure. But I think in sub-zero temps, tucking the camera into a coat when not shooting will help its performance.

Anyone have lens suggestions and/or advice for shooting rally car racing?

Anything around F4 is fast enough. Faster is easier obviously.

Length is a function of how much you want to risk getting hit with gravel and/or cars. Something in the 200-300mm range will let you stay a safe distance from the action.

As for technique, practice your panning shots. Stand on the side of a busy road and be prepared to take thousands of pictures before you get decent at it. Google around for techniques.. cars look really, really boring when you freeze the action, so you're going to want a nice blurred background and spinning tires.

Yeah I don't know about Nikon, but on Canon, some of the newer L lenses not only have an option between IS on/off, but also a choice between two different types of IS, one of which is designed to assist only in the horizontal axis, so for panning. No clue how effective it is practically, as I'm terrible at panning regardless.

It helps with vertical shakes.

You really don't want horizontal IS when doing panning, because the lens will try to compensate for your panning motion, making your picture a horrible disaster.

I question that vertical IS is necessary, it's pretty easy to get a smooth horizontal movement with some practice, but if you got the feature, there's no reason to not use it.

Some cheap lenses like the Canon 55-250mm can detect horizontal or vertical panning and only use one or the other for IS automatically. Any thoughts on how accurate that is? I've tried it briefly on mine and it seemed to work ok but I'm still very new.

This review mentions it.
http://www.the-digital-picture.com/reviews/canon-ef-s-55-250mm-f-4-5.6-is-lens-review.aspx

I took all of these shots on a 55-250mm with IS on (newbie mistake):

https://picasaweb.google.com/mrxzzy/IndianapolisMotoGP2010

Problem is, my discard rate was close to 90%. I took a couple thousand pictures and threw the vast majority of them away due to blur. Even some of the ones I uploaded have a bit of blur on them.

If you're really bored, compare to these pictures:

https://picasaweb.google.com/mrxzzy/24HoursOfLemonsCarShots

Same camera, same lens, but I had IS turned off. My discard rate was a little under 50%. There's a margin of error to this.. I also had more practice under my belt, but I attribute most of the improvement to having the camera properly configured.


tl;dr: Using IS on the Canon 55-250 for panning is a huge mistake.

I don't use Canon, but have you thought it might be the autofocus? I had the most trouble focusing with certain color motorcycles. Also, in one set you are shooting MotoGP, which is insanely fast guys on motorcycles. The other set is car racing, hard to compare these two, I think.

Focus mode was an issue for some shots.. I alternate between MF and AF quite a bit, just to get some practice with both. Results were generally the same, turning off IS gave me the best improvement overall.

And yes, the MotoGP bikes are ridiculously fast. The corner I happened to be shooting from was the slowest portion of the track, they were well under 100mph when I had the shutter open. The car race was probably in the 50-80mph range.

I took a lot of shots of the 250cc and 125cc guys too, with similar results. They're still fast, but not MotoGP fast. ;)

AF was definitely an issue, especially when shooting through the fence. But I was able to mitigate it somewhat by avoiding the center AF point.. going for one of the less sensitive outer points worked pretty well.

I also toyed around by using single shot AF, focusing on one bike, and then releasing the shutter on the bike behind him.

MF felt like it gave me the best success rate, but this is probably because I was only taking single exposures, trying to hit my focus point. With AF on, I tended to shoot machine gun style and this resulted in hundreds of lovely images.

The biggest downside to MF is it limited any particular shot to the one point in the corner that I had focused on. If something interesting happened anywhere else in my field of view, it was impossible to catch it before it was over.

Definitely stay away from photographing family weddings, especially if it's your first outing.

But on the other hand, if you're one of those people who are always "I'm not good enough!" when you might actually be good enough, it may be worth a shot to get involved in other weddings as an assistant. You won't be doing much shooting as an assistant, but it should be pretty educational and if you feel like you want to do it professionally, it'll help with that "could I do it?" question.

Plus, you get a free dinner out of it!

Is it a standard glacier cruise? How much time on land are you going to get, and which parts?

As a one time resident of Alaska, I say take the whole kitchen sink. There will be mountains, and glaciers, and people, and wild animals you'll want pictures of. No single lens will be able to catch all that.

Let me stress the extra batteries thing. You will burn through them absurdly fast sitting around for an hour with the shutter open.

Especially because it's still winter temperatures in March, which sucks a lot of juice out of batteries to begin with.
