Photos come out blurry on Av Mode on my 600D

Hello everyone,

I have recently started using the Av setting on my Canon 600D, I played around a bit on the settings but now my photos come out blurry if I slightly shake the camera when taking.

Unless I'm taking a photo on a table it will just blur.

Can someone help me? Maybe change my Av settings. (I'm shooting in normal daylight)

Thanks

In AV mode, you decide the aperture and the camera will determine the shutter speed. If you do not have the ISO set high enough, it is possible the camera will select a slow shutter speed to obtain a good exposure. This is likely where your blur is coming from.

you're probably experiencing a slow shutter speed.

try increasing the ISO so the shutter speed is increased in AV mode

Try something along the lines of:

ISO 1600
F5.6
1/300 Shutter Speed

Better results?

Heya,

AV allows for variable shutter. It will meter the light and determine it based on that. If it drops too low, it will blur if you move. Try setting ISO to AUTO with a cap at 1600. Do it again, it will likely have a higher shutter speed, at the cost of ISO noise.

When in low light, don't use automodes. Use manual and figure the exposure yourself. The camera has an internal meter that will give you an idea of where you are exposure wise. Use it.

Very best,

When using Av mode, you must keep an eye on the shutter speed (displayed in the viewfinder). If it's too long, you have to open up the aperture and/or increase the ISO.
Are you using a stabilized lens (IS) or not?

Here you are, sorry I'm new to photography so I'm not sure what settings I should do.

be mindful of the shutter speed - if you're confused then Google for the "exposure triangle " ie ISO+ShutterSpeed+Apert​ure.
do your homework and you'll be fine - get back here again for more guidance

EDIT: set your "Auto-Focus Mode" to One-Shot (and not AI Focus) and shoot around f5.6 Av/Aperture or below(instead of f9.0) you got to try it :-)

Unfortunately we can offer guidance but there is no one set of settings that are correct. It varies from shot to shot depending on what you are shooting and what the lighting is like. Blur is usually due to a slow shutter speed combined with either...

  • your camera moving/shaking (because you are hand-holding) or
  • your subject moving.

There is a rough rule of thumb to help with the first one - known as "the reciprocal rule". It states that your shutter speed (in 100ths of a second should be equal or greater than the reciprocal of your effective focal length. In other words, if your focal length is 200mm you need to have a shutter speed of at least 1/200th, if your focal length is 85mm then 1/100th (because the next one would be 1/80th which would break the rule). If your system has image stabilisation this will allow you to further reduce the shutter speed.

Here's a good quick read as to the exposure "triangle":

Here you are, sorry I'm new to photography so I'm not sure what settings I should do.

Your link does not show the shutter speed. If you half depress the shutter button, the shutter speed will show up in the blank box just to the left of the aperture. That shutter speed number will change in AV mode depending on the available light. Like the others, I suspect that that the shutter speed is way too low. You also might not have the image stabilization switch on your lens turned on. If you were shooting in low light with an aperture of f/9 it's very possible your shutter speed was way too low in order to compensate. We need an image to see what was going on.

The rule applies to "full frame" 24mm x 36mm. On a Canon APS-C camera like the OP's, you need to shoot 1.6x faster, i.e. 1/320s @200mm.

I have no idea what auto-ISO does on the OP's camera, but setting the ISO to 400 instead might yield usable speeds at f/9 in many situations. Easier, though, to put the camera back in full auto.

All of the above posts should help. I also recommend getting "Understanding Exposure" by Bryan Peterson. It'll help greatly and it's easy to read.http://www.amazon.com …ds=understandin​g+exposure (external link).

While that book can be very useful, it appears that the OP also doesn't seem to understand how at least some of the basic controls of his camera work.
