I hate this, simply hate it. It's dust on the sensor... HATE IT.
Well, working with DSLR always gets you to suffer from it, so let's think what makes that happen, and what we can do to fix the problem.
First, what am I talking about?
Dust spots on your DSLRs sensor appear as tiny black specks on the image. Theres a good chance you havent noticed the specks. They may only show when youre shooting against the sky at a close aperture. You will see small dots, usually around the corners of the frame.
What causes that?
It's impossible to avoid this dust.
It gets in when you change lenses, or even if you pull the tele in your lenses, it pulls air inside the camera and with it the dust.
What can be done to minimize the dust?
1. Always switch your camera off while changing lenses. The static electricity pulls the dust in.
2. Turn you back to the wind so the wind won't blow the dust into the camera.
3. Make sure you don't have dust on the back of the lens you are changing to. You might just put the dust there yourself.
4. Be prepared with the new lens so you can switch lenses quickly
5. Change lenses the minimum you can. If you have a backup body, use different lenses on it so you won't have to change.
6. Plainly, be careful in the surroundings you change lenses in. You might want to reconsider changing lenses in a sand storm, if you know what I mean...
OK, I got my sensor dirty, what now?
1. Make sure you got it. Close aperture to F16 and shoot against clear blue sky. Check the image. If you see it, youre right.
2. The easiest thing is to avoid using closed aperture. Shallow depth of field will not show the dust (about F1.8-F8), but as soon as you close it - the dust will show again.
Action items - what to do?
1. Make sure you are in "lab conditions". A closed room, good light, and not much dusty air.
2. Your menu should allow a self cleaning option when it locks the back mirror so you will have access to your sensor (that is usually in hiding). In Canon I believe it mentions the sensor cleaning, and in Nikon it's the mirror lock option.
3. After you locked it, remove the lens and gaze at your friendly sensor. Like this...
4. Use a blower to clean the sensor ever so gently. Don't dare to touch it, only blow strong strokes of air to the middle and corners of it. It should be enough to remove big elements.
5. Don't be afraid to do that even if you don't notice dust in your photos. Every 1-2 weeks it's good to do this.
6. I wouldn't recommend anything more than this. Try to see if your sensor is clean by repeating the check. Close aperture to F16 and shoot against clear blue sky. Check the image. If it's still dirty, try the blower again, or give it to a local lab. Don't try the brushes and lotions. Its not that the procedure is so difficultits that the cost of a mistake is so high A scratch on the sensor and it's doomed.
I did a great shot, and I see the dust. WTF?
1. It happens. You see dust you didn't know you had, clean your sensor.
2. Use editing to remove the dust. There are programs that learn your photograph and automatically detects the sensor dust repeating in every photograph. They can get it removed automatically (there is an option even inside the camera menu). I don't recommend it It will sometimes cost you in details, and it will be too late to recover them since there is no record of the photo without the removal.
3. Simply use the cloning tool in Photoshop to get rived of it. When you have dust on the sky area it's even easier using the healer tool.
Any more suggestions?
