C1/C2/C3 - Custom Modes, Revisited

Just a brief update to my previous post on setting up the custom modes on my 40D.

Shortly after writing that post, I read one by wedding photographer, Ryan Brenizer on how he's able to post-process a shoot with an average of two seconds per photo. His big secret is that he's an expert at getting his exposure correct. The second was that he shoots all manual mode.

It's interesting that this never occurred to me. I've been futzing around with different metering modes all this time, usually disappointed with the results. At one point, I was sure that my camera meters dark because spot-metering on someone's face would result in a shot two-thirds to one stop dark. I'm pretty sure now that that was due to caucasian skin being about a stop brighter than middle gray. It was exposing properly, I was telling it that this person's face was gray, when it was much lighter than that.

Most of the time, and I'm sure this is the same with you, I'm shooting several shots in the same room, or same basic lighting. I've been letting the camera determine and re-determine the exposure with every half-click of the shutter. It seems so obvious now that that's a bad idea. When I'd shoot 50 shots in the same room with aperture-priority (Av) mode, I had to individually correct the exposure on every shot. Now, thanks to that invaluable tip, I'm able to spend a little up-front time getting the perfect exposure, then finish the rest of the shoot with the same settings. When I get back to the computer, I need a few minutes with the first photo, then copy and paste those corrections to the rest.

Simple, no?

Now, it's just a tad more complicated than that, of course. Unless you're very far from the light sources, you're unlikely to find a room with consistent lighting across the whole space. I need to be wary of that, and when I determine what exposure I'll be shooting at -- say, ISO 1600, f/2.0, 1/60sec -- I might need to take mental notes that on one half of the room nearer to the lamp, I should quickly adjust to, say, f/2.8.

So, to modify my previous post, I re-set my C1 and C2 custom modes to manual exposure, with a couple of starting points that I find myself often shooting. C1 was for indoor, ambient only, so I chose ISO 1600, f/2.0, 1/30sec. C2 was for indoor, with flash, so I set that to two stops darker, and enabled the flash - ISO 1600, f/2.0, 1/125sec.

It wasn't easy changing the custom modes from aperture-priority (Av) to manual (M) - I had to start over, since the shooting mode is determined by what mode you're on when you're saving the profile. I basically had to start over. No worries.

Next time I'm out in a new shooting environment, all I have to do is take some test shots early on to determine the exposure I'll need. I'll start with C1 mode, find the correct exposure, then save it to C1. Then I'll dial in a shot two stops darker for C2. This should make my post-processing go by much quicker. After only one round of shooting with the new modes, I must say I was impressed. I saw a continuity in the lighting of my shots that I'm not used to. Every shot turned out the same, regardless of whether I was pointing at someone wearing a white or black sweater.

Thanks, Ryan, for pointing out the obvious!

Canon 40D's C1, C2, C3 - Custom Modes I wish I had been using all along!

After spending two weeks drooling over the new Canon 5D Mark II, I started feeling like my 40D was inadequate. Of course it's not, but well, camera envy has its grip on the best of us. Being broke, I decided the best way to upgrade my camera was to pull out the manual and learn all those cool, unnecessary features. I didn't expect that search to get me so giddy!

Many of the newer Canon DSLRs have C1, C2, and some have C3 modes on the mode dial that you can fully customize. I never felt the need to save custom functions - I figured it only applied to a few of the minor features buried in the C.Fn-I through C.Fn-IV menus. Well, that's not the case - it seems that just about every setting on the camera can be mapped into one of these custom mode buckets - even the shooting mode (Av, Tv, M) and the ISO, aperture (in Av or M modes) and shutter speed (in Tv or M modes).

Are you excited yet?

Okay, here's why you should be. You know how you're at a get together and you're flipping back and forth between ambient-only and flash-assisted ambient? Or, when you're shooting fast-action sports one second, and then a portrait of a player as he comes back to the bench the next?

hrm, one more example...

How about you often shoot night shots on a tripod with Live view mode and mirror lock-up, but are tired of switching that setting back and forth every time?

Once you realize how great this feature is, you'll be upset that you only have two or three custom modes to set. You'll have to decide which types of shooting you do the most often, because the goal here is to save all the time that you spend changing the ISO, switching back and forth between Av and Tv modes, and turning on and off the flash. In my case, I take a lot of people shots where I prefer to use ambient, but if I have to, I'll switch to flash. I also like taking my fast lenses outside at night for some real low-light shooting, where I can push every photon as far as possible with this camera.

The following will probably be more info than you'll be interested in reading, but I'm including it because it's something I wish I would have read a year ago. Even if you're not shooting the same types of shots as I am, this should give you an idea of how you can think about these custom shooting modes, and how you can make them work for you.

Here's how I set my modes - your milage may vary:




Common Settings


** Settings common to all modes:
- Quality: RAW - if you're using JPG mode, throw out your DSLR and buy a point and shoot
- Red-eye: off - I never use on-camera flash, so I don't care
- Beep: on - I try not using it, but just can't live without it
- Review time: off - I can hit a button if I really wanna chimp
- Shooting mode: Aperture priority (Av). Most photographers use this mode at all times. I won't go into why, but if you're not using it, you should be.
- White balance: AWB (auto) - I don't care about white balance, because I shoot RAW, I change it later anyway
- Highlight alert: enable - insanely helpful feature - you can always darken a photo, but not when you blow out a section of the photo
- Histogram: brightness - just personal preference
- INFO button: shoot. func - I only use this if the camera's on a tripod and it's more convenient than looking through the viewfinder or on the LCD
- (C. Fn I) ISO expansion: on - I only use ISO3200 if I have to, but I like having the option (yes, I know it's the same thing as ISO1600 -1eV)
- (C. Fn II) - Long exp. noise reduction: off - this is annoying - I can see myself using this, but I'll temporarily switch it if so
- (C. Fn II) - High ISO speed noise reduction: off - no thank you
- (C. Fn II) - Highlight tone priority: disable - no thank you
- (C. Fn III) - Mirror lockup: disable - I use this often, but only on tripod - I have this as one of my quick settings
- (C. Fn III) - Lens drive with AF impossible: focus search on - I can deal with this - I'm capable of letting go of the
- (C. Fn III) - Lens AF stop button function: AF stop - I rarely need to cancel AF when I hit the shutter button halfway, but it's there if I need it
- (C. Fn III) - AF point selection method: Multi-controller direct - I love that joystick - it's great to jump right to the AF point you need
- (C. Fn III) - Superimposed display: On - I need this on to see what I'm focusing on
- (C. Fn III) - AF during Live View shooting: Enable - I rarely use this, but keep it available
- (C. Fn III) - Mirror lockup: Disable - I use this often, but only on tripod - I have this as one of my quick settings
- (C. Fn IV) - None of these are interesting enough to mention

1. Ambient Only
** This is the mode I'm in more often than not. If there's enough ambient light, I'm using it. I only pull out the flashes if I'm looking for a cool effect, or if they're absolutely necessary.
- Drive: low-speed continuous (3fps). This doesn't kick in immediately since there's three shots per second fired, so if I only want one, I can let go of the shutter button. If, however, I'm in low-enough light that I'm afraid of camera shake, I can keep the shutter down and capture a couple shots of the same scene and keep the best one.
- ISO: 1600 - Mainly because I'm usually in lower light
- Aperture: f/2.0 - I find myself shooting people in low light. Even if the lens I'm using at the time is faster than this, it's a good starting point which will get most of a face in focus close in. Note that I set this aperture when my fast f/1.4 50mm was on the camera. If I'm using a slower lens, it'll just use the fastest aperture it has.
- Metering: Spot. I'm a fan of spot mode when people are in the scene in lower light. I usually meter on someone's blurred out face, the exposure lock, focus, reframe, then shoot
- Exposure compensation: +2/3eV - in spot mode, I like to meter off of a person's face. Caucasian skin is about a stop brighter than middle gray, so I have to adjust for this or get dark shots. I'm playing it safe by not going all the way to +1eV, but if I'm shooting a lighter-skinned person or notice my shots coming bright or dark, I'll adjust. Note that this adjustment goes away after I change metering modes
- (Flash Control) Flash firing: disable - this is one of my favorite on-camera settings, because I can have a flash on camera and turned on, but not use it when this setting is disabled. This way, I can bounce between settings very quickly and not have to turn my flash on and off.
- (C. Fn III) AF-assist beam firing: Disable - In this shooting mode, I'd rather not annoy people with the focus beam. I keep this in my quick settings, in case I need it. Again, it's great to be able to turn this mode off in the camera, so I can have a flash on camera and turned on, and not have it fire a focus beam

2. Flash, with ambient dropped two stops
** This is the mode I retreat to if it's too dark for my Custom Mode #1
- Drive: single shot. I'm using a flash here. If I took back-to-back shots with it, everyone in the room will instantly hate me.
- ISO: 1600 - I'm only in this mode because it's too dark for Custom Mode #1, so ISO 1600 is clearly not enough. I will be using a flash in this mode, but rather than rely 100% on flash, I try to get at least some ambient by keeping my ISO high. I'd rather deal with some noise (which is well-controlled on the 40D) than get a shot with zero ambient when I'd really like to have some.
- Aperture: f/2.0 - I was originally going to set this to f/5.6 to get the subject safely in focus, I realized that if it's too dark for Mode #1, I'd be shooting with the same shutter speed as in that mode if I drop the aperture down two stops, then drop the exposure two as well. So, I start this out at f/2 so I can quadruple the shutter speed from Mode #1 by default. I can always override this while shooting. Note that I set this aperture when my fast f/1.4 50mm was on the camera. If I'm using a slower lens, it'll just use the fastest aperture it has.
- Metering Mode: Center-weighted - I figure in this mode, that's appropriate. I'm probably shooting a person standing right in front of me
- Exposure compensation: -2eV - this lets some ambient light fill the background a little darker than the subject, rather than leave black backgrounds, while letting you take a shot four times quicker than in Mode #1
- (Flash control) Flash firing: enable. Again, this is great to set on the camera - I can quickly switch to Mode #1 and not use the flash for a shot or two, then switch back and the flash is still powered up.
- (External flash func. setting) Flash exp. compensation: +2/3eV - I usually find my shots a little dark when using the flash. This might be due to metering on flesh tones that are a little brighter than middle gray. I keep this as a quick setting so I can override it if needed.
- (C. Fn III) AF-assist beam firing: Enable - In this shooting mode, I'm in people's faces with flashes, they can deal with some flash beam to help me focus. I keep this as a quick setting so I can override if needed

3. Low light shooting - get as much out of the lighting as you can without flash
** This is the mode to use when I'm trying to shoot where the average shooter gave up already - perhaps 30-60 minutes past sunset
- Drive: high speed continuous. I usually reserve this mode for fast-action sports shooting. However, the point of this mode is that I'm in such low light that I want to take advantage of my low-light shooting hardware. Most likely, I'm shooting around 1/20 of a second or slower, and there may be some serious camera shake. The best way to deal with camera shake is to take several shots, then throw out all but one.
- ISO: 3200 - this is actually a pushed ISO, which means it's ISO 1600, but taken at -1eV, then brightened by a stop. This brightening is a lossy operation, so more grain is introduced. It's a last-resort method of shooting, which is what this mode calls for.
- Aperture: f/1.4 - again, we're trying to get as much light to the sensor as possible while keeping this hand-holdable. Note that I set this aperture when my fast f/1.4 50mm was on the camera. If I'm using a slower lens, it'll just use the fastest aperture it has.
- Metering Mode: Center-weighted. I figure that there might be some high lighting contrast in this frame as there usually is when I shoot at night. I like sodium vapor, neon, and other lights against the setting sun and deep blue night skies. I rarely frame these shots with the bright lights in the center, and I don't mind if these have to get blown out towards the light source, leaving a nice colored halo around them. The shot is nothing if all you see is the lights - they're less important than the rest of the scene, and since I'll rarely keep them in the center of the frame, I've chosen a center-weighted metering mode which will favor the non-well-lit sections of the shot. If I used evaluative metering, I'd have the problem of the few bright lights in the shot keeping the rest of the shot dark, and the rest of the scene is what I'm after.
- Exposure compensation: +2/3eV - I usually find myself brightening the shot by a little bit, so I'm exposing to the right
- Flash Controls I turned off all flash firing, including for auto focusing. The idea of this shooting mode is to not draw a lot of attention to myself while blinding people with the flash.




Conclusion
I just started using these modes, so I'll have to see how well they work for me. So far, so good. It's really exciting being able to change my ISO, flash settings, exposure compensation, aperture, metering mode, and miscellaneous settings with the turn of the dial. I love being able to _quickly_ jump between flash and ambient shooting, then step outside in the dark and be a little less conspicuous, and make the most of the photons. And, as soon as I'm done using the custom settings, I can go right back to Av, Tv, or M modes, which still remember and share these settings among the three modes as well. I'm sure these custom modes are often overlooked, but if you sit down and think about the few common ways you keep shooting, you can save yourself a lot of time when shooting, and of course we all know that in the time you spend fiddling with the dial, you've just missed the moment.

The hardest part of setting this up for yourself might just be in deciding what two or three shooting modes you find yourself using the most. After that, you'll probably get as excited as I am about this - it kind of feels like you're building your ideal camera when tinkering at this level.
