Hey Guys,
Hope you all are doing fine?
Got the camera last night, quite a bit of learning to do, but i'm doing what i can, just took some test shots from Nikon Sample images, followed what they did with these shots of my own.
These were took in the A Mode, tell me what you think?
The pix are fine for a start. Keep at it! I would start by observing the background and removing things like that water hose; even OoF, it's a distraction.
Anyone with a good eye tell me how would I know if dust is on the sensor or in the viewfinder, because I see a few particles in the viewfinder, but don't know exactly where it is.
Don't worry about dust! Dust on the front of a lens has absolutely no affect on the image projected on the sensor or to your eye via the oVF. Don't worry about dust on the mirror and absolutely NEVER try to clean it off!. It has no affect, but the scratches you will create might.
If you see dust in the oVF, they are undoubtedly on the bottom of the viewing screen. These can probably be removed with a Giottos Rocket Blower. Never try to brush them off as the screen is a very soft Acrylic plastic and is easily scratched.
NOW, as to dust on the sensor. There must be thousands of posts on DPR about this. There must be hundreds of websites w/ instructions. OK, few of the DPR posts and few of the websites are correct. Many are just opinions floated by beginners after their first attempt didn't ruin anything. Many are just vendor sites promoting their products. Reader beware: Observe who is giving instructions!
Dust doesn't get on a sensor. It gets on the filter mounted most forward. Some cameras have both low-pass [anti-alias] and IR-blocking [hot-mirror] filters. Which one is farthest from the sensor catches the dust. There are ultrasonic shakers attached to this filter to dislodge most dust. Make sure it is enabled.
The filter is not very easy to damage, but you can do it. It's kinda expensive to replace, as it requires taking the camera apart.
Always use a 3-stage process, starting w/ the least invasive:
- W/ the mirror up for cleaning [all cameras have this feature] blow with a Rocket Blower. Get close, but don't let it hit anything. Check to see if the dust is OK.
- Using a soft brush, designed to clean lenses, wipe the sensor in several directions. Then blow it off again. Check to see if the dust is OK.
- Using Eclipse fluid and a proper swab, dampen the swab w/ 1-2 drops and wipe the sensor horizontally. Turn the swab over and do it again in the opposite horizontal direction.
To check for dust:
- Go outside on a cloudless day. Don't get the sun near the image. Use a long FL and a small aperture [at least f/22]. Take a picture. It should not be white but rather a proper blue sky.
- Use a small, white 1-LED flashlight [like goes on a key ring]. Position the LED at least 10 feet away, pointed at the camera. Remove the lens. Darken the room. Point the camera at the light from the LED. Adjust the exposure time to get a light-grey image. It helps to use LV for this, w/ the camera on a tripod.
Look at the image and you will see spots. The LED approach will produce small diffraction circles; the sky approach will produce small, blurry blobs.
