Ok, I've just read this and still dont get why someone would use AV or TV for any reason other than laziness.
If it works for you, then just use it - there are no 'Rules' here to break

How do you know? Presumably experience?
So, is it recommended that newbies like me should shoot in ALL modes including the P modes to become familiar with them and know which ones work when, and what their failings are?
I suppose it is mainly.
Like Dave says, there are no hard and fast rules here.
I was shooting an indoor equestrian event recently. One end of the arena was really dark, the other was brighter. If I'd gone for manual which do I set up the camera for? Far better to take the guesswork out of the equation and let the camera decide. As it happens I went for aperture priority instead of shutter as I wanted the fastest shutter speed I could get. Therefore I just picked the maximum aperture I had and let the camera pick the shutter.
On the other hand at a showjumping event recently the backgrounds were a pain, some messy, some dark, but most were big white tents. Most of the time I chose to take a reading from the grass, put the settings in manually and knew I'd get a decent exposure for the horse and rider. If I'd left the camera in Shutter/aperture priority mode it would have messed up because of the big white background. Using spot metering wouldn't necessarily have worked either as the horses were different colours, some black, some white, some a nice 18% greyOthers would have handled that differently. Sometimes if there's only one awkward bit I'll use shutter/aperture priority and lock the exposure just before the rider gets to the problem bit. It varies.
The beauty of the auto modes, including P, is that they handle average lighting situations really well. It's just really dark and really light scenes where they struggle. Bear in mind that all you're doing in manual, if you use the settings the camera gives you, is adding another step to the process.
Personally I would recommend you shoot in whatever mode you're happiest with. It sounds like you already recognise the situations where you need to override the meter so stick with what you're most comfortable![]()
Manual all the time. I really don't understand why anyone would use AV or TV (or nikon equivalent) because surely if you can dial in +ve/-ve exposure somp, then you can shoot in manual?
Or am I missing something obvious?
Ok, I've just read this and still dont get why someone would use AV or TV for any reason other than laziness. And I certainly don't get why using manual and the camera's meter is the same as shooting Auto!
So, why would AV or TV be beneficial? I must be missing something. :shrug:
TBH I think the only thing you are missing is a few important brain cells
using manual and then using the camera's metering system isyou are only doing the same thing as AV or TV does.
68lbs said:1. The camera's metering often gets it wrong
2. In AV you can't 'freely choose' your shutterspeed.
3. In TV you can't 'freely choose' your aperture.
But back to the point...
I'm no pro, and wouldn't even class myself as a competent amateur. I am a beginner, so please correct me and help me if I am wrong. From what I am reading though I believe these are facts...
1. The camera's metering often gets it wrong
2. In AV you can't 'freely choose' your shutterspeed.
3. In TV you can't 'freely choose' your aperture.
Why would you use guesswork when you've got a perfectly good tool for that built into the camera? That's a bit like disconnecting your speedometer, guessing your speed and relying on the Gatso to tell you when you get it wrong, bit of a high risk strategy. Maybe not a great analogy but the meter is really very good and more accurate than guess work most of the time.And just for the record, rightly or wrongly, I use guesswork and the histogram for metering, but I brought this up some months ago and it's an entirely different discussion.![]()
So... you can't ALWAYS get what you want in AV, or TV. And you certainly can't in P or Auto. However, you are in 100% control in M and the image that you take is down to you, and you only.
Therefore, for me as a beginnner, it makes sense for me to ALWAYS shoot M (manual). If I take a shot and it's not as I want, I know it's me at fault. With each and every shot, I am fully aware exactly what aperture, shutterspeed, ISO, is being used - because I have set them. Yes, it's a lot to think about. Goddammit, don't I just know it. The number of times I forget and leave the ISO on 800! :bang: But if I want slightly more DoF, more motion blur, I can choose without changing modes.
In manual I have the ability to effectively chooose AV or TV, so it's more versatile. I really don't get what the problem is here.
Why would you use guesswork when you've got a perfectly good tool for that built into the camera?
The thing to remember is that if you've only got one chance to get the shot and you've set it wrong it's gone forever. That's especially true if you're using Manual, guessing the exposure and chimping to see how it came out. The guy using AV or Tv however will be packed up, have it processed and be selling it to the papers for £000's.![]()
Ok, I've just read this and still dont get why someone would use AV or TV for any reason other than speed. And I certainly don't get why using manual and the camera's meter is the same as shooting Auto unless you just line the needle up in the middle every time!

I'm not eloquent or experienced enough to put forward an argument, but here is my story...
When I started this photography thing 6 months ago I had a quick read of the manual, and starting shooting AV (aperture priority). It seemed to offer the right sort of creative control to me. But, everything came out crap! Bar the odd shot. From posting on here, I found out that it is the camera's meter. It is easily fooled. So I did a little more reading and came up with 2 options. Either dial in some -ve/+ve exposure comp or learn how to shoot manual. I chose the latter, and couldn't believe how easy it was. Set camera on spot (or the 400d's equivalent, which is a big spot). If the bit you're metering is dark, make sure the meter reads under, if the bit you're metering is bright, make sure it reads over. Shoot. Look at the histogram and if you think you can push the histogram a little more to the right, do so. Or if you've completely blown it, stick the shutterspeed up a few notches.
Surely this is the same as AV. Except rather than under/over reading on the meter, you'd dial in the exposure comp based on what whether the bit you're metering is dark/bright.
If shutterspeed is more important than DoF, then I set shutterspeed first, and apply the same process adjusting the aperture to obtain correct exposure.
So, why would AV or TV be beneficial? I must be missing something. :shrug:
