I'm new here so I don't know if that has been discussed or not. I have been reviewing some of the creative modes on my T3i and have come to realize that they are nothing more than a convoluted way of controlling the exposure triangle. I'm just not so sure that they are that effective for beginners looking to break away from Auto. It seems that it would be easier to learn M, Av & Tv than it would be to figure out all these creative modes.
Does anyone here use them? Or, did you use them while you were learning photography? Or are they simply for novices taking vacation photos?
They are more of a SIMPLIFIED way of "directing" the exposure triangle to settings that millions of analyzed photos predict have a better than average chance of being very close to optimal, given all the data that a small onboard computer can analyze. Nikon pioneered multi-segment metering, which they invented and patented and called "Matrix" metering, with at that time, a small library of 100,000 anaylzed photos that had been fed into a database, and then cross-checked as to results and patterns as far as what later became known as the EXIF info standard.
Later, they added more information, and more data points to analyze, as well as to compare MEASURED colors against measured reflectance values, as well as the information the camera is providing, such as scene brightness level and white balance information, as well as basic stuff people seem to forget about: day/day/time zone, which shows seasonal weather trend likelihood to a high degree. And also, simple stuff, such as shutter speed requirements for say "night scene + flash" as opposed to say "sports mode", or "shallow DOF portrait mode". Given location, time of day, and scene brightness level, as well as DEAD-easy stuff like blue sky and green foliage, I gave a 4+ hour photo lesson to a lady yesterday using her Nikon D5100, and the "scene modes" were amazingly good for her. We also paused for a few minuytes at the start of the fay to set up AUTO ISO with a 1/160 shutter speed minimum and a Maximum ISO of 800. The camera with the SB 700 and on board or pop-up flash performed amazingly well with the 18-55 VR, the 55-200, the 70-300 VR, the 70-200/2.8 VR and the 85/1.8 G, and for a "manual only lesson" with the 105/2.5 Ai-S and the Lensbaby 2.0 with the f/5.6 disc.
Subjects included macro: white water rafters; portraits in sun and in shade; florals, leaf and flower details, pastoral grassland scenes; woodland scenes, and a few really close-up shots, as well as a segment on flash. I was impressed by how amazing the D5100's matrix metering was in the various modes, and also the way it "tracked" the focal length using the 70-300 VR, since we had BRIGHT summer lighting.
With modern high-ratio zooms lenses being popular on beginner/hobbyist cameras, some of the VERY popular 18-200, 18-270, and 18-300 or 28-200 or 28-300mm lenses with BIG maximum aperturt drop-offs, it is basically impossible to shoot in "MANUAL" mode and do a zoom out to maximum length in a fluid situation without stopping to make a MAJOR aperture-click adjustment OR a major shutter speed click adjustment.* What people forget is that the people MOST likely to use these modes have "one-button" cameras, where the one button + control wheel adjusts exposure and can ALSO adjust +/- exposure compensation....
The * is excepting people using Pentax or Nikon cameras with AUTO ISO enabled, and the ability of those brands' system to MAKE a SET manual exposure and a set f/stop "be the right exposure" by adjusting ISO up or down faster than a person can ever hope to click a wheel six, or nine, or twelve times...
Basically, the people who use high-end cameras that have full controls, and TOP LCD's for info, and dedicated shutter and f/stop control wheels, tend to poo-poo these modes...which their cameras do not even possess...so in other words, you'll hear a lot of crap talked about these modes by people who've never really themselves figured out what they actually "do", or what they "might be able to do", let alone, "how to leverage automation"...
These modes appeal to people who either 1)understand the 1970's era concepts that were developed first with "Programmed" exposure or 2) who just want to get the right "type" of settings for easily recognizable situations, like....night party + flash, or "sports action" mode, and so on. Most of the beginner/hobbyist/fun cameras have adopted these modes, which basically use decades of research and modern microprocessor technology to SET THE CAMERA the way an experienced photographer would likely set it, given alllllllllll the data that can be collected in milliseconds, by an onboard computer.
A really BASIC point that most high-end gear shooters forget: with 18-300mm lenses that now "top out" at f/6.3, there is a HUGE number of "clicks" that need to be re-set when zooming from short to medium or out to full tele in many exposure modes. Beginners are the most-likely to be using that kind of lens. The need is usually for BOTH a speed or f./stop adjustment AND ALSO an ISO shift as well. This is just one major reason why the hobby cameras have these modes. If one does not "run out of f/stop" in bright light, one can EASILY "run into a shutter speed blur" issue when using an 18-270 or 28-300 or whatever. A shutter speed I can hand hold at 18mm is 1/6 second with about 75% success; at 200mm, can I hoold 1/6 second with 75% success rate....NO...with a one-button camera, the "scene modes" provide a way to get the camera set up FAST; add AUTO ISO into the mix, and you have a beginner shooting perfectly-exposed shots in 4 hours in FAST-paced shooting scenarios.
