Image Quality

12 years 2 months ago - 12 years 2 months ago #198109 by Aquaticbob
So I have been taking pictures all my life, and decided about a year ago to make photography a major hobby of mine. I just recently upgraded to a Canon 60D (from a 20D) for Christmas. Now I'm wondering why a lot of my images are turning out in low quality. I shoot in Raw format, and I feel like most of my shots are well composed. Anyways, this picture is taken directly from my camera, and I will give all the info on it (the light was a little low if you are going to point that out, I know).

Dimensions: 1920x1080 (originally, but the site wouldn't let me upload it at that size 5184x2912)
F/11
100 ISO
17mm focal
EF-S17-85mm f/4-5.6 IS USM lens with B+W UV filter
Any reason for why it looks sooooo poor would be nice (yes, I did make sure my shot was in focus).

The image is too small to judge the focus / sharpness. But, in addition to underexposure, the contrast is low. If you are using Canon's own Digital Photo Professional you can fix that right in the camera by setting the Landscape PictureStyle, or a custom PictureStyle (I suggest base PictureStyle of Standard) with the Contrast bumped up a few notches. If you are using an Adobe editor, then you will need to do the contrast adjustment in post.

I will put up another larger size. The image looks as if it isn't in focus, and isn't sharp at all. I usually use photoshop for editing, and I do shoot on the landscape picture style.

The UV filter is in good shape? No hazing? As a check compare to one of your shots with the same lens, but no UV filter.

I think it might be my lens. I just took a couple pictures with and with out the filter and they looked the same. With a different lens though, the pictures are slightly sharper, but not extremely sharp. Anyway I can have the pictures be sharper or does that just come down to lens?

I can see the softness. My first guess would be camera shake. The shutter speed was 1/6th. Is your tripod sturdy? Did it get bumped? Are you using a cable release or remote? If you are consistently getting this sort of softness at all shutter speeds, and you are positive the camera is being held secure, then it could be the lens or camera.

:agree: In low light you may have to bump up the ISO. At 1/6th, you definitely need a sturdy tripod and use a remote release or the timer. Possibly even mirror lock up or live view. My 60D with the 18-200 is really crisp.

Shoot, learn and share. It will make you a better photographer.

My first thought was a low quality lens... I was assuming this was a lens used with your other camera but if it was a kit lens... that might be your answer.

I shoot a 60D too. The performance of the body at high ISO is one of the cameras strong points IMHO. Bump that ISO us a bit and try it, then bump it again. You might be surprised at how high you can go before the noise starts to show. Also you need to discover if there is a sweet spot on the lens. Try different aperture setting to see if that effects the image quality.

I understand that you were going for the soft milky look in the water - which you got BTW - but shoot another image at the faster shutter speed then clone over the soft water to the crisp shot... just thinking outside the box for this particular shot.

I also see softness, but overall I think the image is too under expose to really give you input on the quality.

img834.imageshack.us/img834/2857/img1936hdr.jpg is another version of the same picture with an HDR effect and a couple other edits. I could have done more to that picture but I didn't. I always use a sturdy tripid for my shots too.

I think this picture might provide a better example: img20.imageshack.us/img20/6775/img1974hdr.jpg

Is this your only lens? sure looks like focus....

You will not be judged as a photographer by the pictures you take, but by the pictures you show.

Good point. 1/4th to 1/30th is the shutter speed range where mirror movement can be a real problem.

If you rule everything else out (I still think it looks like camera shake), and this softness is a result of the lens it's not just a matter of it being a lousy kit lens, IMO. I'd say it demonstrates a damaged or malfunctioning lens.

I'm using the same tripod as I used to use with my 4x5 cameras, which should be overkill for a small format DSLR, and I can still get camera shake. I almost always notice mirror shake if I don't use MLU in the 1/2 sec to 1/60th range.

Does the lens have image stabilisation? make sure it's switched off when on tripod
