I'm sure you already know this, but you have some dust on your sensor. This is really evident on the Golden Gate Bridge shot. They're easily edited out of the picture, but it's easier to blow the dust off the sensor.

All in all, they're very good pictures---the indoor shots are not as good, but that's a hazard of working with available light. If you didn't push the ASA up to 800 or 1600, you can try that next time. It will allow you to use a faster shutter.

San Francisco Bay is one of the more photogenic spots on the planet. You had a beautiful day, and you used it all to good advantage.

Nice job.

Tom

P.S. This is a huge download. You might try reducing the pictures a little in size---maybe to 1024 X 768 or something.

Heh,. Belmodo is being exceptonally polite :D

The excepted maximum dimensions seem to hover around 800 pixels on the long end.. you can push it up to 1,000 or so if need be,. but these full size images, and so many at once is quite a long download even on broadband.

Thank you TOM for your feedback.

when I took the golden gate shot I was almost directly facing the sun and that made the picture look like little blur.

But How do i check if I have dust on my sensor and how do I clean it with out damaging the camera.

Sorry for the big pictures and I will put the samller ones soon.

Thank you.

CDS,

Can you please commnet on my pictures. I will put the smaller Images soon.

I did not cheng any setting in the camera except to adjust my focus.

Thank you.

I took the liberty of copying a portion of your picture to show you examples of dust. The user's manual that came with your 10D gives a very concise description of the best technique for cleaning the sensor. Basically, you use a low pressure blast of air to clean it off---not a brush.

I usually do it before and after every shooting session.

Anyway, the dark blobs are dust. Hope this helps.

Good luck,

Tom

Hi Tom,

Thank you again.

It is a good learning experince.

Thank you.

Not to be picky (or anal-retentive or anything) but there are no shots there of SFO. SFO is the airport. The city is SF or San Francisco.

hmm, i always thought that spots from dust on the sensor would be in focus, no? wouldn't out of focus dust spots be somewhere on the lens? Or am i thinking backwards here?

Not all dust is a nice clearly defined solid. Very often it is a microscopic ball of fuzz with no clean edge. Then, there's a clear layer over the sensor that holds the dust a distance (albeit slight) off the actual surface of the sensor causing it to be slightly out of focus. I agree---logic would seem to dictate that dust should be clearly defined in your images, but it is just diffuse enough to end up being the blob we're all so familiar with. Dust on the lens(es) probably wouldn't even register on the sensor to any significant degree.

By the way, I was doing a little checking on different websites. I though I was doing everything right about minimizing the problem, but today, I read another precaution which is to turn the camera off while changing lenses. Apparently there is a small electrical charge in the sensor that acts like a ‘dust magnet.’ I'm not sure I ever did it any other way, but it will be one more thing to check.
