Why I like DSLR Live View Shooting

(Notes: Article slightly updated in February 2015. Original article title was “Canon EOS 5D Mark II: Why I like ‘live view’.” These days the Canon 5DII is no longer my primary camera, but the points remain much the same.)

It took me a while, but I eventually came to rely on live view a lot in my photography.

Back when I acquired a Canon EOS 5D Mark II I assumed that the main improvement over my previous camera would come from the 21 megapixel sensor — the previous camera had only 12 MP. Other features of the updated version of the Canon 5D series seemed like they would either be minor improvements or perhaps not be of any use to me at all. I lumped the “live view” feature of the camera into the latter category. I understood that it would permit me to view the scene “live” on the rear screen, but I failed to see any big advantage over looking through the viewfinder, and much of what I had heard suggested that there would be serious downsides to the feature.

Consequently, it wasn’t until after I had the camera for some time that I actually thought to try out live view, which locks up the mirror and shows a video version of the live image on the rear display. At first the feature seemed very counterintuitive, since I was completely used to looking at the traditional kind of “live” view – the one seen through the viewfinder. On top of this, with live view enabled the normal autofocus system is turned off – or, more correctly, works in a very different way. However, once I did start to use live view I realized that it is one of the most significant and useful features of the Canon 5D Mark II for certain types of photography. How is it useful? Here is a list:

  1. Live histogram – You can display a live histogram on the rear screen in live view. This histogram display updates instantaneously as the scene changes or as you make exposure adjustments. Rather than making an exposure, checking the histogram, making adjustments, and then shooting again – you can simply get it right the first time.
  2. Manual focus – In many cases live view provides the very best method for achieving accurate manual focus. While you can manually focus on the ground glass of the normal viewfinder, really critical manual focus is very difficult using that approach. However, with live view you can zoom in to 5X or 10X or higher magnification and focus precisely on any point in the frame by moving the portion of the image shown in the magnified view. This is like having a 10x loupe built into the camera. There are more advantages related to manual focusing, but I’ll break them out separately below.
  3. Accurate Depth of Field – Determining what will and will not be sharp enough at a given aperture has always involved a bit of guesswork on a DSLR. You can press the Depth of Field (DOF) Preview button and try to check this visually, but this is even more difficult than trying to achieve accurate manual focus via the viewfinder. When you press the DOF Preview button the optical viewfinder becomes dark, making it difficult or impossible to accurately assess DOF. However, live view automatically adjusts the display brightness when you press the DOF preview button – so you can see the image as well at f/16 as you can at f/1.4. Not only that, but you can again use the 5X or 10X or higher magnification on any part of the scene to check focus of any area of the composition with great accuracy.
  4. Night photography – It was while doing night photography that I first gave live view a serious try. I was shooting some industrial subjects under full moon and artificial light and trying to focus on the side of a dimly lit building without much luck. AF could not acquire focus, and in the darkness I couldn’t see enough detail to focus manually through the viewfinder. However, with live view — keeping in mind that the camera adjusts the image brightness on the screen — my very dark subject was light enough that I could manage to focus manually and get a sharp image.
  5. Neutral density filters – I sometimes use a 9-stop neutral density (ND) filter in order to make rather long daytime exposures. The 9-stop ND is so dark that you cannot really even see your scene through it and composing and focusing are impossible. My previous method of operation was to compose the scene and focus first, switch off the AF feature, attach the ND, and then shoot “blind.” However, if I needed to change the composition or adjust focus I would need to remove the ND filter again and repeat the laborious process. I quickly discovered that the live view can display a useful image even with this filter attached, permitting changes in composition, manual focus, and even depth of field checks while the filter remains in place.
  6. Optional display grid – Several different electronic grids may optionally be superimposed on the live view display. I often switch on the  3 x 3 (three horizontal and three vertical lines) grid to check that the horizon is level or that vertical lines are actually vertical.
  7. Awkward camera positions – As long as you can still see the LCD, you can place your camera in positions that would not work if you had to compose through the viewfinder and would otherwise have to “shoot blind” or miss the shot. I’ve found it useful for some wildflower shots where the camera had to be down low among the plants. In addition, I can shoot with the camera on the tripod raised well above eye height with live view – this has allowed me to, for example, shoot over the tops of tall fences or simply get a higher perspective.
  8. Tilt/Shift lenses – Although I’m not a tilt/shift lens user, several photographers (see below for the link to the first of them) pointed out that live view greatly improves the usability of T/S lenses and makes it easier to achieve critical focus.
  9. Shooting in windy conditions – Here’s a new and unexpected use of live view that I discovered in January 2011 when shooting with a 400mm lens in windy conditions. In such conditions I’ll often wait until  the wind have briefly calms enough to get a sharp image, but it can still be a bit of a guess. However, if I activate live view and use the 10x magnification I can directly see the effect of the wind on the image and then simply hit the remote release button when I see the vibration stop in the display.
  10. Elimination of mirror and shutter vibration – Because today we push small original images from cropped sensor or full frame sensor DSLRs to greater and greater print sizes, all factors that affect potential image sharpness become more critical. When it comes to minimizing mechanical vibration within the camera, live view is the current best solution. Because the mirror is already raised so that the image from the sensor is visible while focusing and composing, “mirror slap” vibration is completely eliminated. In addition, by selected an electronic first curtain option, the shot can be initiated without motion from the shutter curtain. According to tests I’ve seen and judging by my own experiments, when you are doing critical work from the tripod this can materially help when it comes to eliminating blur from camera motion.
  11. Camera Sound – In some situations the sound of a DSLR is objectionably loud, both from the slap of the mirror rising and falling and from the physical motion of the shutter curtain. On at least some cameras with live view, there is a first and second electronic curtain setting – called mode 2 on my Canon DSLR – that starts and ends the exposure electronically rather than flapping the shutter curtain across the sensor. It also leaves the camera in live view mode at the end of the exposure, rather than flipping the mirror back down. This significantly reduced – though doesn’t eliminate – the volume of sound from the camera, so it can be useful in certain situations where the shutter/mirror sound might otherwise be too loud.

This list could be even longer, but I’ll stop here for now. Are there any downsides to using live view? In some situations there are, so live view is not called for in every photograph.

  1. Battery life – The use of live view significantly reduces the number of frames you can expose before your battery runs out of power. I have made 400-500+ photographs on one battery with the 5D II without live view and not run the battery down to the point that I would think about switching. However, with heavy live view use on a few occasions I got only a few more than 200 shots. I limit my use of live view in situations where battery life is an issue, such as when I go on long backpacking trips. (Hint: Rather than leaving the camera in this battery-draining mode, sometimes it pays to focus and compose in live view, then switch back to the “normal” mode with mirror lock-up enabled to wait for the right moment to make the exposure.)
  2. Active subjects – While live view is great for relatively static subjects (such as architecture and landscapes, for example) it is far less suited to shooting active subjects. For those I’ll stick to using the through-the-lens viewfinder.
  3. Portraits – While you certainly could shoot portraits in live view, I think that it is sometimes better to either peer through the pentaprism viewfinder at the almost-real view seen there or, better yet in some cases, step back from the viewfinder/camera and just look right at your subjects. (Update: Someone with far more portrait experience than I have recently made a very good a point about getting away from the viewfinder and communicating directly with your subject – though you could do that independent of Live View.)
  4. Autofocus – Autofocus is possible in live view, but either of the options for AF are a bit clunky. (They are improving as of this most recent update.) I virtually never use live view with AF, but almost always use it with manual focus.

When I first wrote this article, soon after beginning to use live view, I wrote, “In the end, although I shoot more often without live view than with it, for certain types of photography I now find it indispensable , including much urban and natural landscape work, night photography, and when working with neutral density filters.” Much of that sentence still stands, but the truth is that in my photography I now use live view most of the time.

UPDATES:

Todd Klassy points out that live view is very powerful for those who shoot with tilt/shift lenses.

Regarding my point about portraits, someone with far more portrait experience than I have recently made a very good a point about getting away from the viewfinder and communicating directly with your subject – though you could do that independent of Live View.

Welcome to Visitors from the 5dmk2 Blog

I noticed a spike in visits this morning that I’ve traced back to a reference in a post at the 5DMk2 blog at 1001 Noisy Cameras to yesterday’s post here about Live View on the 5DII. Thanks for the link, and welcome to visitors entering my blog world through the 1001 Noisy Cameras doorway. (And for those who arrived via a different route, if you are interested in the 5D2 and related topics, you should wander on over to the 5DMK2 blog once you finish up here.)

The two points I wrote about yesterday (the benefits of live view for depth of field preview and for shooting with very dark ND filters) are not the only benefits of the live view feature. For example, I earlier wrote about its value when doing night photography, and quite a few of my recent wildflower photos took advantage of it. Before long I hope to write up a more complete article outlining the range of uses for live view.

If this is your first visit to my blog, take a look around. I post a daily photograph (recent work has come from Death Valley and a number of central California locations) and the occasional opinion or news piece. You can subscribe via RSS (link near the top of the page) and members are welcome to post discussion messages.

Canon EOS 5D Mark II: Two More Reasons to Love Live View

Yesterday I was at Point Lobos shooting a variety of wildlife, nature, and landscape subject. As I worked I found myself using the live view feature of my Canon EOS 5D Mark II very frequently – partly for reasons I’ve written about before, but largely for two reasons that I’d like to briefly mention.

Much better depth of field preview – Everyone knows about the small depth of field preview button on the body near the lens. Since the lens is open to the widest aperture when you focus you cannot tell what your depth of field will be until you push this button to stop down to the aperture that you’ll use for your shot. There are two problems with this technique: you cannot judge sharpness critically enough across the frame in the viewfinder and the viewfinder becomes incredibly dim if you stop down to small apertures like f/16. Put those two problems together and the usefulness of the preview button is diminished. However, when you use live view the camera automatically adjusts when you press the preview button and the image is still plenty bright to see on the LCD. Even better, you can zoom in to 5x or 10x magnification to carefully check sharpness. All in all, this makes DOF preview a much more useful feature when live view is used.

You can compose a photograph when using neutral density filters to extend exposure
– At one point this weekend I was using a 9-stop neutral density filter to make exposures of the surf with durations in the 10-20 second range. My usual practice is to compose the shot and, if necessary, manually focus without the filter attached. Once the shot is set up I attach the filter. Unfortunately, the filter renders the scene virtually invisible through the viewfinder. Recomposing or manually focusing requires removing the filter, making adjustments, and then reattaching the filter. I discovered yesterday that live view mode can display the image in the LCD even with my 9-stop ND filter in place, allowing me to make changes to the composition/framing or adjust focus without removing the filter

Canon EOS 5D Mark II: Live View and Night Photography

I have shot a few thousand frames with my Canon EOS 5D Mark II now. I’ve photographed a variety of subjects including a few days of rainy professional bicycle stage racing, several landscape subjects, and a productive evening of night photography with The Nocturnes at Mare Island Naval Shipyard. I plan to eventually write up something resembling a comprehensive report on my experience, but so far there hasn’t been time. With that in mind, here is a short piece on one new feature in this camera and my experience with it.

Among the photographic subjects that interest me is night photography, often of urban and industrial subjects, but occasionally of wild landscapes also. There are a number challenges to shooting in very dark conditions, but one of the more interesting is getting good focus in conditions where auto-focus often can’t find a target to work with and where it is too dark to manually focus. (I wrote a bit about this in a recent piece: “Hints for Night Photography.”)

During my last Mare Island shoot I discovered that Live View provides a very useful option for focusing at night. On the 5D II, the Live View mode raises the mirror and lets you look at a “live view” of your scene on the rear LCD. In very dim light the trick is to find something that might provide a manual focus target, center the rectangular LCD indicator over that “something,” zoom in to 10x magnification on this object, and then focus manually on the LCD image. I was amazed at the low light levels at which this works quite well. A vertical line in a wall, the edge of a window, a bit of cyclone fence, or a small light – any of these become decent manual focus targets using Live View.

When I started my Mare Island evening shoot, using this camera for the first time at night, I mostly did things the old fashioned way. By the end of the evening, in any very dim situation I was successfully and much more quickly getting good focus using Live View. I’m confident that night photographers are going to find that this is a very powerful and useful feature.
