On top of calibrating your monitor, you have to profile your printer. If you scan with silverfast, you can have it print out a calibration page, scan it, and it generates an ICC profile for your printer. I haven't done it since I only have SF for a slide scanner, anyone tried it?

Scanner-based profiling is super lovely and not even remotely accurate. If you have a printer that's otherwise completely unusable it might be an improvement, but you're way better off just paying for a proper profile (assuming you're not using an Epson, in which case you should just use Epson's profiles).

$40 for one time use is a lot compared to $160 for a lifetime. All of my research points to calibrating at least once a month if I am remotely serious about having a properly calibrated display. It seems I should just bite the bullet and purchase another tool for my arsenal. Am I mistaken? And is buying a $160 spectrophotometer like bringing a knife to a gun fight?

If I am not printing myself, my printer should be able to supply me with a profile or something, yes? I am going to check the place out in person today and will be asking them about it but I imagine if my monitor is calibrated appropriately then their super-dee-duper printers will have the correct profiles.

I have a Canon Pixma Pro 9000 and I never have a problem when I use Canon paper. I tried using some Illford and downloaded their ICC profiles off their site, but I keep running into WYSIWYG problems. I'm guessing I need to make my own profile for that paper? I don't print often and Canon paper is good and priced decently so I never bothered to fix the problem. Then again I got a big pack of 13x19 Illfort that I don't want to go to waste.

You're better off buying one and having it around. I think it'd only make sense to rent if you're a business and can charge someone else for it and write it off. You're going to at least get a couple years out of it, probably more.

If you're sending out photos edited on a calibrated monitor out to a good lab, you shouldn't need to do anything more. That's their job. You could get the ICC profiles from the lab and Soft Proof your images, but from everything I heard, Soft Proofing doesn't work and is a waste of time.

Great idea. Seems I'm on the right path then - to buy a calibrator. Should I just go with the most popular of my searches and buy it on Amazon or does someone have great first hand knowledge of why I should choose one over another?

I've a quick question, I was told about a good deal on a Tamron 17-50 2.8, with the caveat that it was a nikon, no worries I thought, I'll just get an adaptor so I can use it on my Canon 600D no problems. Upon the arrival of both items, I notice that it just reads the aperture as 0. This is the adaptor that I bought, is it a problem with the cheap adaptor I bought or will I have to adjust the aperture in another manner?

That was a very bad idea, you should sell it and buy a Canon version. When you put a lens not made for your camera on, you lose all electronic control. No autofocus and no changing the aperture. You might as well be using a broken lens.

Adaptors exist so you can mount old lenses that never had any AF or any electronic control to begin with. These old lenses should have the aperture control on the lens itself.

How do you shoot moving objects at night with a flash?
I was shooting some drifting, and the flash froze the wheels and car in place when it fired.
As you can imagine this sucks mega balls.
What are you supposed to do to keep motion?

I am pretty sure what you're asking is impossible.

Get a tripod and just shoot the light trails.

e: or boost ISO way up and don't use a flash

e2: or get a flash that you can fire without it being synched to the shutter and flash it like three times while you're exposing, then you get three ghost cars! That could be cool.

Shoot at a slower shutter speed and use 2nd curtain sync. The flash will still freeze the car but you'll also get a light trail from the motion.

Why 2nd curtain? Because the mode fires the flash at the end of the exposure rather than the default of at the beginning. If you use first curtain you'll get a unnatural light trail that goes in front of the car, with 2nd it's behind the car.

Can you post an example and the settings you used? I'm very interested in this. From what I understand, shooting at like < 1/100 on second curtain should give you the effect you want.

Are you using a calibrated monitor along with Costco's color profiles? I'd be surprised if they still had a blue tint and probably would contact someone there to let them know if you're still seeing issues.

Anyone know an easy way to modify the EXIF time for a group of photos by an offset of a number of minutes? I shot a wedding yesterday and forgot to sync the times between the two cameras. Lightroom was able to change the hour, but not by a smaller amount that I've found. They're about 11 minutes off which is pretty annoying.

If you can pan with a telephoto, you can pan while your flash is strobing.
I mean ideally you'd want small bangs along the exposure then a big bang before second curtain, but no one makes anything like that I think.

I just bought the Velbom macro slider, both because of the good reviews and because it is insanely cheap compared to others I've been reading up on.

Question for those who have used it though: Is this rail easy enough to use when going beyond 1:1 magnification?

So I have a question about CPL's.

I have a B+W 77mm that I've had laying around for awhile because I started reading about how CPL's do partial polarizing and having spin the thing to get a 'right effect' and whatnot. That sounds annoying. Is it possible to put it on for maximum polarization then set the exposure compensation up a stop or two, or will that completely negate the benefit of a CPL and/or distort the image in some negative way?

RangerScum
Apr 6, 2006

lol hey there buddy
The reason you have to spin a CPL is because depending on what angle you are shooting to the sun, the angle of light coming into your lens changes and you need to be able to spin the filter to accommodate for that. As for the exposure compensation, I don't think it will really be necessary as your camera should be able to adjust its metering automatically.

OK so I've got something really really strange happening, extra flash is making my pictures more under exposed.

This is the setup...



It's a 350D on full manual with a sunpak on camera flash.

The flash to the right is the Vivitar 283 on M mode on an optical trigger.

So if I sit on the chair and just have the on camera firing, this happens



OK, so lets see what happens if I keep everything as it is and fire the Vivitar to get some fill on the right side...



I really don't understand this at all, how can adding light make my pictures under exposed????

My guess is that the Vivitar is triggering off the on-camera metering preflash and that the added light is causing the camera to think there's more light from its own flash than there actually is and thus turning down the power. Naturally the Vivitar can't recycle fast enough to flash again during the actual exposure so you end up with no flash from the Vivitar and less power from the on-camera flash.

I just reread your post and realized you have a Sunpak on the camera and you're not using the on-camera flash, so the solution should be simple if my theory is actually still correct: put the Sunpak on manual mode instead of TTL.

Turn your on board flash to manual instead of TTL. In TTL, though it looks like only one flash is going off, like MrBlandAverage said you actually have two going off; the pre flash so the camera knows what it needs to do and the real flash. In manual it's just one flash.

I'm leaning towards MrBlandAverage's theory but another problem could be your sync speed. Unless you have a flash with high speed sync (430 & 580ex) you can't shoot at faster than 1/250 depending on your camera model. When working with flash it's always best to work in manual mode in your camera.
