Question about Canon EOS-10D Digital Camera

1 Answer

Incorrect Light Meter

In all the automatic settings the pictures are being over exposed due (I assume) a problem with the light meter reading. Even when I am outside in bright sunlight my 10D pops up the flash.

Faulty light meter

Could you give us a little more detail? What make and model camera or light meter? How is it faulty? Is it consistently over- or under-exposing, or erratic? How do you have it set?

My camera over exposes everything - the shutter stays open for about 2-3 seconds. except when on video settings. No matter what I set it at nothing changes.

Looking down at the top of the camera, check the left knob. This is the exposure compensation dial. Adjust it to "0". If set one way or the other, it will make pictures darker or lighter. This comes in handy when the image has a lot of dark or bright areas - moving this dial will allow you to make the bright areas darker or the dark areas lighter when you camera's light meter is setting the exposure in a way you do not want.

If still having trouble, make sure the right knob (Mode) is not set to M or Manual. Switch it to Program or Auto and try taking a picture again. You might even want to set the outer knob (ISO) to AUTO as well to reduce the chances of an incorrect setting. If it now works as expected, but you want to shoot in M, you will need to learn how to use the meter to select the correct combination of aperture (f stop), shutter speed and ISO to obtain the desired results.

Oh, experiment with the exposure compensation knob when you have a chance, learn how it can help correct overly dark / bright scenes. Good luck!

My ANT light comes on when ever i push the mic button but my SWR isnt that high

The meter will be more accurate and an external meter will be even better. If they show good disregard the ant light it is adjustable. It may have been set to sensitive from factory. These erroneous SWR reading can be the side effects of a PEAK & TUNE if the coils have been spread but that should also show on meter.
SWR meter calibrations
  • Switch (S/RF SWR CAL) to the CAL position.
  • Push and hold mic button
  • While holding mic button adjust the SWR CAL knob so the meter needle swings to the CAL mark on the meter
  • While still holding down the mic button, set the (S/RF SWR CAL) switch to the SWR position, to read the SWR reading. Note: When switched to SWR position the meter needle should ideally be as far to the left as possible. Anything over 3 is not acceptable.

How do i take 12 dark, 12 light and 12 perfect pictures with 400 black and white film on a vivitar 3800n camera?

For normal exposure, set the ISO dial to 400. Meter normally, adjusting the shutter speed and/or lens aperture until the green LED in the center lights up.

For dark pictures, you want to underexpose about two stops. One way is to meter as above, then stop down the aperture two stops (larger F/numbers) or increase the shutter speed two stops (larger number) or a combination of the two. Alternatively, set the ISO dial to 1600 and meter normally.

For light pictures, you want to overexpose about two stops. Meter normally then open up the lens two stops (smaller F/numbers) or slow the shutter speed two stops (smaller numbers) or a combination. Alternatively, set the ISO dial to 100 and meter normally.

You can also experiment. Over/underexpose one stop, then two, then three, then four, and even five. You might want to take a notebook with you and write down what you're doing. Record both the setting and how many stops over/under it is. When you get the film back, you can refer to your notes and see what happened.

No power, backfiring thru the carborator. need to know what the problem is

Hello! lets check the Manifold Absolute Pressure (MAP) and the Throttle Positioning Sensor (TPS) in that order...if you have a multimeter and a wee bit of experience using one both of these sensors can be tested...If not replace the MAP first and the TPS second...

The MAP has a three wire connector with wire colors Orange/White...Blue/Light Green...And Black./White...using two safety pins push one into the rear of the in-place connector into the Blue/Light Green...The other into the Black/White...connect the + probe of the meter set to read 5 volts on to the Blue/Light Green pin...the - probe to the Black/White pin...turn key to on...Meter must read at least 3 volts...If not MAP is defective...

Using the same technique lets test the TPS...Three wire connector Green/Light Green...Orange/White and Black/White...Safety pins into Green/Light Green and Blue/White...Set meter to read 5 volts...Place + probe of meter on Green/Light Green pin...And - probe on Black/White...start the idle meter must read less than 1 volt (.85)...slowly increase the idle (as best you can)...Meter should rise smoothly to 4 volts...If it skips, jumps or acts erratic the TPS is defective...See pictures below...Guru...saailer

Nikon f3 hp light meter wont work

I'm interested in this as well. Just installed fresh batteries, light meter says 1/80 in all shutter settings faster than 1/60 (otherwise it shows the correct setting). Since 1/80 is the flash sync speed, it may be that the camera thinks there's a flash attached. But it is not...
Strange thing is that one time (I tried a couple of times today) the light meter worked correctly; it showed other timings and they changed as I turned the aperture ring...

Pictures very dark even with a light meter

Digital cameras operate on a delayed shutter. Your Camera and flash are not synchronized. Try adjusting flash to a slower speed. Or the cameras Fstop value to get them insync.

If you half push the shutter the rangefinder and focus circuits kick in and will adjust to available light and give you your best picture. Do not ever push the shutter in one step. press it slightly to get the best focus and then push the last millimeter to get the picture!

Pictures Becomes white (Excess Exposer or ISO)

I'm not clear about your last sentence. It sounds like you may have accidentally set the camera to use exposure compensation to over-expose the images. To reset this, see page 27 in your user manual. If you don't have the user manual you can download it here from Kodak. If you said in your last sentence that this is not the case, I apologize for not understanding you clearly.

If this is not the case, then the light meter in the camera may be malfunctioning, telling the camera that it doesn't have enough light.

1) Make sure the light sensor is clean. This is the lower of the 2 small light buttons on the front of the camera, to the left of the lens as you face the camera. If that doesn't help try:

2) Use a - setting in Exposure Compensation to under expose the images to compensate for the damaged light meter.

If neither of these help, then it needs to be sent in for repair, or replaced. (If the camera is out of warranty it is likely that the repair cost will exceed the value of the camera and you should simply buy a new camera.)

Light Meter

Check your metering settings. Are you using centerweighted, matrix, or spot metering? Try setting camera to matrix metering, use program mode 'P' and adjust exposure to default.

CANON Rebel RTI Outdoor pictures are dark

learning to use light metering correctly can have its challenge.
the manual will guide you on how to set up to read light from the subject. spot metering a dark area will cause general overexposure, or a washed out look. spot metering a bright area will cause a dark image. if you are on spot meter and shoot two people standing together against a bright lit background, your meter will see between them if they are centered, and read all that bright background, setting the camera to a less sensitive combination of aperture / shutter speed, resulting in a dark image. use field averaging meter setting and be sure you are metering the subject and not the background. try shooting a wall that is fairly clear of other colors and uniform it light hitting it, you should have a correctly exposed image. since it works in other modes (at least 1, anyway) then it is unlikely you have an exposure compensation issue. that is the only other non defect issue that would cause your problem.
once you confirm that you have these settings correct and still get a dark image, its time to have it serviced.
good luck
