Choosing aperture and shutter, which first?
Hi there, I was wondering how do people "usually" set those parameters
in their cameras to get the desired exposure. I mean, with the camera in full manual mode, do you first choose the f-stop (looking for depth of field) and then you adjust shutter time until the exposure will be correct or you do it in reverse order, first shutter and then aperture to meet correct lighting? I guess that depends of what is the subject, if it has fast motion you'll probably set first a lower shutter time, and then check for f-stop... And so on... But my question is about "normal" pictures, those without fast motion or low depth of field required (portraits)... Which method works best? Shutter-Aperture or Aperture-Shutter? Any other? Is that just a matter of personal preference? I own a point and shoot digicam, with shutter and aperture priority programs, so I don't have all the control over those variables that I would like to, but I wanna get the best from it while I win the lotto and get a DSLR ;-) -Quercus- -- Yo uso Software Libre Debian GNU/Linux (Sarge) Kernel 2.6.7 OpenPGP id: 700F3CC6 Mi weblog :: http://quercus.nosomos.org |

Photography is a science, but more important for most of the people here, it is also an art. The science of photography can be taken car of by .... science. Our automatic cameras can make those decisions for us. Since you asked the question, you want the answer as it applies to art and art is . . . within each of us and not something that we can get by asking. You can do well by learning the science of how they relate to each other and how they effect the results. Then you, the artist can make the decision that makes the art. Good Luck -- Joseph E.

His question was quite valid and led to various replies being variations of 'composition first - Aperture'; 'movement control - speed'. He can apply that to the art. Who's Pacaso?

Since a particular composition includes depth-of-field as a compositional element, it is usually natural to select aperture first. From there, the film ISO and the metering dictate the shutter speed. (metering technique and desired exposure placement will vary the results a little too). If a tripod is not used, then the shutter speed may take precedence. In some cases, shutter speed is more important (to freeze or purposely blur a moving object, for example). I mean, with the camera in full manual mode, do you first choose the f-stop (looking for depth of field) and then you adjust shutter time until the exposure will be correct or you do it in reverse order, first shutter and then aperture to meet correct lighting? See above. Whether in manual or A (or S) priority the outcome dictates whether the image is to be controlled by one or the other. I guess that depends of what is the subject, if it has fast motion you'll probably set first a lower shutter time, and then check for f-stop... And so on... Yep But my question is about "normal" pictures, those without fast motion or low depth of field required (portraits)... Usually aperture choice dominates ... it goes to composition (whether shallow or great DOF is desired). Which method works best? Shutter-Aperture or Aperture-Shutter? Any other? Is that just a matter of personal preference? They work equally well, they are in fact no different wrt to exposure. They are different with respect to desired outcome. I own a point and shoot digicam, with shutter and aperture priority programs, so I don't have all the control over those variables that I would like to, but I wanna get the best from it while I win the lotto and get a DSLR ;-) Most who use the semi auto exposure modes tend to use aperture priority except where subject movement control or camera shake dictate a higher speed. Note, with a DSLR, you can also vary the ISO. So if you need greater DOF as well as a relatively high shutter speed, then a higher ISO can be selected (at the expense of noise).

When intending to keep f-stop and speed properly related to each other, I generally prefer to use f-stops because I can mentally gauge what the depth of field is going to be with the f-stops I chose to use. If I'm in a manual mode, after metering the scene I'll generally set the camera's speed and manually open or close an f-stop, or do both, as I see the scene I'm about to photograph. The essential thing is to become familiar with the film your using and become so familiar with the camera your using, that you instinctively know what you're going to do when you are about to photograph a scene. nick -- Yo uso Software Libre Debian GNU/Linux (Sarge) Kernel 2.6.7 OpenPGP id: 700F3CC6 Mi weblog :: http://quercus.nosomos.org |

I mean, with the camera in full manual mode, do you first choose the f-stop (looking for depth of field) and then you adjust shutter time until the exposure will be correct or you do it in reverse order, first shutter and then aperture to meet correct lighting? For me it depends on a variety of options - which camera body I'm using, what I'm photographing etc. My oldest body is manual only. On it I normally set shutter first because the shutter control is on the top of the body and is a bit of a pain to set while composing a shot, whereas with the aperture on the lens it is quick and easy to adjust. So, I'll set the shutter to something in the range of the aperture I'd like to use, so if for example i'm in bright light and want a large aperture I'll dial up something fast on the shutter, then make the slight adjustments with the aperture until I get the exposure (bearing in mind there isn't a huge difference of DOF between for example F2 and F4). Only in very specific circumstances do I set an aperture then adjust the shutter till I get what I want. A slightly newer body that I have, has aperture priority auto exposure, which I normally use. So in this instance I set the aperture to what I want and the camera does the shutter to whatever is right. Of course in the viewfinder it shows me what it's doing, so if I want a specific shutter speed, I just dial the aperture ring until the shutter is right. Even for things like waterfall shots I do this - Just dial the aperture up until the shutter needle is pointing to about 1sec. My newest body is of the fully automatic variety, and 90% of the time that's just where I leave it. I mainly use this body for family snapshot type shooting - where I don't give a hoot if it is using F2 or F22, I don't care if it is using 1/30 or 1/1000, all I care about is that when I point the camera in the right direction and press the shutter button that it is going to take a shot. for the occasions when I do have something specific in mind, I normally will use Aperture priority mode, because DOF is my main concern (portraits, close ups). On the odd occasion when I am doing waterfalls, night streets etc, then I will use Shutter priority or full manual but it is rare. Even for sports shooting I don't use shutter priority - In that situation I use aperture priority and dial up something nice and wide, because I know that no matter what the light the camera will still be able to get exposure - if I dialled up a fast shutter, it might not be able to open the aperture wide enough, in which case the camera stalls, I have to change down a shutter speed, and I miss the shot. I guess that depends of what is the subject, if it has fast motion you'll probably set first a lower shutter time, and then check for f-stop... And so on... But my question is about "normal" pictures, those without fast motion or low depth of field required (portraits)... Which method works best? Shutter-Aperture or Aperture-Shutter? Any other?

Thank you all... That was really useful :-)
I like the aperture-first approach, and I think that would work fine with a SLR, but not with my p&s :-( Compact digital cameras have greater DOF, and you can hardly get the blur effect in the background, even with the lowest f-stop. And in aperture priority program you have a limited range of f-stops availabe, depending of the focal length selected (I think this is common even in SLR in auto mode?) and as there won't be so much difference in using f2.2 or f5.6, attending to DOF, I'd better use shutter priority and adjust later the aperture with the exposure bias control. Yes, I know I do need a DSLR :-) Ok, thanks again for your answers. -Quercus- -- Yo uso Software Libre Debian GNU/Linux (Sarge) Kernel 2.6.7 OpenPGP id: 700F3CC6 Mi weblog :: http://quercus.nosomos.org |

I set my camera to 1/250 shutter speed in shutter priority mode and let the metering system choose the aperture (f-stop). As a street photographer, I have learned the my selected shutter speed is the slowest which freezes nearly all pedestrian motion, but still allows for some vehicular traffic motion blur. Since I usually have a very sepcific main subject supported by background elements I don't necessarily care about depth-of-field. I use background more for framing than identification of my main subject. In totality, my photographs show that places tend to remain similar while people are constantly in a state of change, sometimes by way of different people and sometimes by way of the same person in about the same place on a different day. So, my camera is set to 1/250 in Tv mode. For those curious, I shoot Tri-X at EI 200. Michael |
