Question about Canon EOS 40D Digital Camera

1 Answer

I have one red pixel shines up in the dark back ground with 1/15s speed and 400 ISO settings. I tried to use manual clear method to map it out but does not work. I tried 3-4 times from 30s to 2 minutes. What else I can do to get rid of it? Thanks.

Do you get the same effect with different speeds and/or iso settings? If so, theres nothing you can do to get rid of a dead pixel other than to have the factory refurbish it. If not..sorry...can't help you further.

What is an ISO or ASA? where is it on my Minolta Maxxum 400si


There should be a button that says ISO on it, or just a set of arrow buttons. ASA/ISO are the same thing, and indicate the speed of the film being used. 100/200/400/800/etc. Not setting the camera to the proper setting will result in dark or light images.

If you can't find your ISO setting, try searching Google for your model and you should be able to find a pdf download of your manual for free.

Nixon S8100 fairly new camera, nice pics if the subject doesnt move but horrible pictures if object moves. Very blurry.


If everything in the picture is blurry, you are moving the camera when you press the shutter button. If only the subject is blurry and the background is clear the problem is too slow shutter speed. If this is cause by movement of the camera you must learn to SQUEESE the button while being sure you don't move the camera. It just takes a little practice. If this problem caused by a shutter speed that is too slow, it is remedied by increasing the ISO "film" speed. Even though you have no film, the camera has a "speed" setting that relates to that. The higher ISO value increases the camera's sensitivity to light and thus allows for faster shutter speed. Normally the ISO choices are 100, 200, 400, 800, 1600. Try using 400. The ISO setting is in one of your camera menus. 400 is fast enough to solve your problem in all but very fast movement of either the camera or subject. Using ISO above 400 will cause your pictures to look grainy and not as sharp. Use the highest speed only when absolutely necessary. Slower ISO numbers produce the finest grain and thus the sharpest pictures. It a trade off between ISO and shutter speed because the exposure is a combination of the ISO and shutter speed and lens opening. Each one effects the exposure by half or double.

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.

I'm having problems with the settings on my Canon EOS 400D. When I take pictures in AV mode I can get quality pictures but in TV or M modes the pictures always come out so dark even when taking them...


You need to understand the relationship and teractivity of aperture, shutter speed and iso. In Av mod, you choose the aperture and the camera makes thw shutter speed agjustment, In Tv mode, you set the shutter speed and the camera makes the aperture adjustment, In manual, you have to set both shutter speed and aperture manually. If the ISO mode is set to AUTO, the camera chooses the sensors sensitivity to light automatically. Change to specific ISO
(200-400 for daylight and 799-1600 for night). Take a picture in AV mode and note what shutter speed the camera chose. Then switch to TC mode choose the same shutter speed and see if camera chose the same aperture(f-stop) you chose in first shot. Change to Manual and choose same f-stop and shutter speed the camera chose for you in the other modes. Compare all three photos. They should be almost if not exactly the same exposure wise.
In Tv mode choose a dlowers shutter speed, In Manual choose a combo of slower shuuter and wider f-stop(smaller number). Read your manual.

I bought this canon rebel t2 film camera recently and used film with ASO 400. Portraits look ok. but the landscapes, especially the sky area look dark and grainy. I used ef 28-135mm usm lens. Any solutions...


That's odd that the pictures would be coming out under exposed unless the previous owner has gone into the camera functions and switched the ISO from auto to manual. Another reason is that the exposure compensation has been activated and set for - exposure

Under "normal" use the camera will read the DX code on the film canisters and adjust the ISO automatically. However the previous owner may have shut this off in preference to setting the ISO manually. Even though you have ISO 400 in the camera the ISO on in the camera setting may be ISO 1600.

Checking for the Auto ISO and exposure compensation is fairly easy as you can see the film canister through the film window or you know you have loaded 400 speed film. on the LCD panel at the back of the camera is an ISO icon and exposure compensation.

Make sure the ISO for the camera is the same as what you have loaded and if the exposure compensation is to the right of 0 then the resulting picture will be dark. Move this back to the Zero.

I wasn't able to find an exact manual (if you don't have one) for your camera but have found a camera with similar. Here is a ling for that manual.

My pictures are blurry/horrible.


(*)First set your camera for the maximum number of pixels for the memory card in the camera at the time. Or put another way, use the setting that gives the least number of pictures for the card in the camera.
(*)Second, your ISO speed is too high, use ISO 400 under bad lighting conditions, ISO 200 bright sun, ISO 100 even better if you are young and can how the camera steady.

I am using D90 with programe Auto ISO 400, in clear day sun light my picture get very dark, but on same settings in door with auto flash I get very clear result why?


ISO400 is too high of a sensitivity to use in full day light. Set the ISO outdoors to ISO100 and learn how to use your exposure compensation. The meter in the camera is easily fooled in bright contrasty conditions, so if you are getting consistantly darker shots outdoors increase the exposure compensation a stop or two. Another way is to learn how to use the camera in manual mode and you find you will have better control over the exposure.

Trying to take pictures in low light conditions inside a theater.


when you use high ISO like 800-1600 it will create big novice on image, and when you using law ISO it will be dark for sure.
so the solution is switch cam to TV mode and put into very law shutter speed and use ISO 200-400,make sure you are connected to tripod or else you will not get fine results with law shutter speed. point is when you use law shutter speed camera will take more light to censor even with law ISO your images will be perfect.

Having problems with the flash\ blurred and grainy images


You should not use the flash for these shots (unless you connect a powerful external flash), it won't help you at this distance. You should use the shutter priority mode and experiment with shutter speed (no flash) to get the best result - for sports action it should probably be faster than 1/100 sec. If the light is too low you may use higher ISO setting - 200 or 400 (though higher ISO will result in grainier images, it may be your only option for blur-free photos).
