At what temps do I have to worry about condensation in the lens when coming from outdoors to inside? I just bought a Canon 100-400mm and am paranoid about this now.

So what do you do if you do see condensation in there? Sounds like a bad thing to have...

I'm a beginner, so this is probably a beginner mistake, but I've been having a lot of problem with aperture priority mode on my camera. In full automatic mode my camera was taking a picture at f/4 and shutter at 1/60 second (using a Canon Speedlite flash if that matters). If I put it in aperture priority mode and f/1.8 the camera takes the picture with a shutter speed of 1/10 second. Focus is manual and unchanged between pictures, and ISO was 400 for both. Why is my camera choosing such a slow shutter speed when I'm in aperture priority mode? None of the pictures turned out at all.

TheAngryDrunk posted:The reason you were able to get 1/60 before is because of your flash. In AV mode, your flash isn't on by default. You can turn it on and that should give you a faster shutter speed.

I took a bunch of pictures last night with my new 7D and noticed a lot of noise in most of my pictures like what you can see in the cropped picture below: 1/500s f/5.7 ISO 1600 400mm Is there something that I'm doing to get this kind of noise? Not all pictures have it, even at 3200 ISO, but the majority of my pictures from last night are ruined due to it. The red pixels are not so nice.

sensy v2.0 posted:Why are you even shooting birds in daylight at ISO 1600? The picture was taken in a valley with lots of tall trees casting shadows everywhere. The water was a murky brown too. I'm fine with noise at high ISOs, but not if it's red blotches that are visible even on the uncropped version. Sounds like this is due to a screw-up on my part though, and not something I can expect if I had done everything correctly. InternetJunky fucked around with this message at 15:43 on Apr 18, 2010 |

What kind of metering should I use for a scene like this: Unfortunately I used spot metering (with the spot being on a super dark bison) so my background went to poo poo. Also, is there a good primer out there that describes when it's a good idea to change the exposure compensation? I see some photos where people have changed it but I have no idea why they did it.

dakana posted:Well, you just described an incidence when you would change exposure compensation -- you know that the bison was super dark, and the spot meter read it and so the exposure was too high. Thus, if you were going to spot meter in a situation like that, you would (ideally) dial in exposure compensation to compensate for the fact that you know the thing you're metering off of if is darker than 18% gray -- meaning you'd decrease the exposure with compensation of, say, -1 stop.

Apologies if this is a common question, but what's the best way to get dried water blots off a lens? They are very dried on there.

Thanks for the advice on the rally car question everyone. Something I couldn't find when I was looking at panning techniques is whether or not to leave IS off or on for my lens while panning.

I have the opportunity to get a really great lens for cheap, but the lens was dropped at one point and took a bunch of damage. Owner says the lens was sent for repairs and works flawlessly now, but looks rough. It's a local deal so I can go and put my own body on the lens and run some tests, but I'm not sure what to check for really. If you guys were in the same situation what would you look for to ensure the lens is completely fixed? (it's a 200/1.8)

My sister is a pilot for the air ambulance service here in Alberta, Canada. Yesterday she asked me if I could bring her crew some food when they were scheduled to land at the hospital near me, so I lugged my camera along to get some shots of them landing, etc. Aside from treating me like a terrorist, hospital security warned me that I'd be in trouble if I took any pictures of the hospital itself. That forced me to stand in about the worst spot possible to capture the helicopter landing and all my shots were ruined. Just wondering if anyone has heard of this type of restriction before in Canada? I figured I'm pretty much screwed since that was probably the most exciting thing to happen for security in months and it was their big moment to flex their muscles, but for next time I'd love to at least be able to show them something that says I'm allowed to shoot whatever I want if I'm on public land, etc.

tuyop posted:Is the air ambulance service military at all? Photography is handled internally by the military and we/they're very suspicious of anyone with a camera who isn't authorized. You're not even technically allowed to take photos of your friends on a course or firing rocket launchers or anything.

This is a bit of a long shot, but do any of you have experience using this RainCoat product for long lenses? I'm looking for something to cover my lens/body while kayaking to protect against water spray and my current system of covering the whole thing with a towel in the bottom of my boat is both clunky and not super effective. The product I linked looks great, except the back end where the camera body is. There's a lot of loose material there that looks like it would get in the way of the view finder and I'd love to hear from someone who's actually used it to find out if it gets as annoying as it looks. I'm also interested to hear if there's alternative products out there that protect against water and dust.

Here's a bunch of questions rolled into one. My parents, who are now quite long in years, have thousands of old family photos. Before the information is completely lost, I would like to scan these photos and create a digit album that contains the photos, descriptions of who's in there and other details, and produce something that is shareable with other people easily. Questions: 1.) Does anyone have a scanner recommendation? 2.) Are there any scanners that come with software that allow scanning of multiple photos at once (i.e. place 6 photos on the scanner bed and have 6 separate photos imported into lightroom/photoshop)? 3.) What's the best way to associate descriptions with the photos in a way that allows for other people to see these comments? 4.) Is there anything that offers the facebook functionality of identifying specific people in each photo? Basically what I'm trying to avoid is creating something like a smugmug gallery with descriptions of each photo that are lost if I ever move away from smugmug. Any help/advice would be most appreciated!

Tor posted:My parents went though the same thing. They had a service to do the scanning for them. I had recommended https://www.scancafe.com to them (mostly because I heard their name durning a public radio fund drive). I got them one of their value packs. They sent a box to them, and they just had to pack all the things in that they wanted scanned and send it back. The original photos were returned in the same condition they went out in. The scans came back on a DVD. quote:We still had to deal with your question #3. I figured what we could do, was have my father use Lightroom to tag all his photos and make them into collections and then save or upload these in a useful way. What we ended up doing (since I couldn't figure out what he was doing wrong in Lightroom over the phone), was just make a new set of folders on his Mac - one folder for each "event" or whatever he wanted. Hopefully the next time I am back east, I will be able to help him with with the tagging so that he can get a bit more in-depth with what he is doing.

Dumb question time: in this video I found about mounting photographs https://www.youtube.com/watch?v=YAJmy9l2MUo, what is the front and back material he's mounting the picture on called? Is the front and back the same material? I tried to find something like this at Michaels yesterday and when I asked about mat board I was shown foamcore, which is obviously something much different. I would like to hang a whole bunch of photos and the method shown in that video seems like a great way to do it since I wouldn't need to do any dry mounting, which looks like a more complex process. How do you guys hang your pictures?

Leviathor posted:Foamcore is what the photo attaches to. Mat board frames the photo. If you have a frame with an incredibly short rabbet depth you might consider framing against 4-ply mat board. Foamcore is very rigid stuff; mat can sag or warp, foamcore won't.

I thought we used to have a photo printing thread, but I couldn't find it. I've just run out of the Epson Ultra Premium Photo Paper Luster that I bought when I picked up my photo printer and now I'm trying to find an acceptable replacement. The cost to replace this paper seems to be about $35/50 sheets and I was hoping there was a different brand of high-quality photo paper that was similar to the Epson stuff that I could use instead. If someone knows of a good alternative, and/or a cheap place to order it I would be most appreciative.

Just curious -- for those of you with a NAS for storage, do you happen to know how fast you are able to transfer your files from your workstation to the NAS? I have 12TB NAS that I keep all my photos on, but the transfer rate from my computer to the NAS is 11 MB/sec tops. This is really slow and makes it hard to work with my files on the NAS. I'd love to know if this is a normal write speed for a NAS or if I've got a problem in my network somewhere. To give an example of how bad it is, I bought a backup HD yesterday so that I could copy my photos from my NAS onto it and store it somewhere out of my house, but just my photos from my recent trip are taking 12 hours to copy over alone. It would probably take me 2 weeks of copying to get my entire photo library on there.
