Shutter speed and aperture

Is it really true that I can't adjust shutter speed or aperture? Does the camera, in every situation, set both of these automatically?

You can change the settings when you are not using the smiley face setting. Turn camera on press menu go to sensitivity to change film speed, EV compensation to allow more or less light.

Bought cheap extention tubes, now camera wont recognize the lens. How do I use them

Set the exposure mode to "M" (Manual). You'll have to set both the aperture and shutter speed yourself.

You'll also get no exposure assistance from the camera's light meter. You can review the picture after taking one and/or use the histogram to tune the exposure.

I have a Nikon D40 and when it's in M and S mode the shutter stays open for too long and my pictures come out completely white.

What shutter speed(s) are you using? What happens when you use a faster shutter speed? In the S and M modes you are responsible for setting the shutter speed, and you can set it to anything within the camera's range.

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.

Best settings to capture fireworks?

It's a little difficult with this camera since the slowest shutter speed is 3 secs. You need to have the timing right to get the best result:
Set mode dial to M, Select shutter speed with 4-way switch up and down : 3 secs. Now select Aperture: Hold down +/- button and select aperture with the same 4-way button, up and down. Choose F8, which is the smallest opening. You need to have the camera on a tripod when taking the picture. If the picture gets to dark, adjust the aperture. If it gets to light, you adjust the shutter speed, making the timing even more difficult.

How do I change the shutter speed on the Fuji S8000fd

Set the camera to Shutter Priority AE by turning the mode dial to S. Press the +/- button to open the setting screen, then press up/down to select the shutter speed.

You control the shutter speed the same way in Manual mode. You also select different shutter speed/aperture combinations the same way in Program mode.

You can indirectly control the shutter speed in Aperture Priority AE by changing the aperture and letting the camera set the appropriate shutter speed.

How do you change the shutter speed on the finepix s5500?

That depends on the selected shooting mode.

In Program AE, press the exposure compensation button and then up/down on the 4-way button to change the shutter speed/aperture combination.

In Aperture Priority AE you can control the shutter speed indirectly. Press the exposure compensation button and then up/down on the 4-way button to change the aperture, and the camera will adjust the shutter speed to suit.

In Shutter Priority AE press the exposure compensation button and then up/down on the 4-way button to change the shutter speed. The camera will adjust the aperture to suit.

In Manual press the exposure compensation button and then up/down on the 4-way button to change the shutter speed. You'll have to press left/right on the 4-way button to select the appropriate aperture.

I cannot find my manual and would like to know what the MASP settings are for. Last night I was at a good site to help;however, I cannot find it again. I have a P80. also how do I set the camera to get...

P (Program): Camera sets shutter speed and aperture, but allow you to change to another equivalent exposure (Program Shift).

S (Shutter Priority): You set the shutter speed, the camera selects appropriate aperture.

A (Aperture Priority): You set the aperture, the camera selects appropriate shutter speed.

M (Manual): You set the shutter speed and the aperture.

F-stop issues

See pages 36&37 of the manual.

If you haven't got one, you can download it here.

In M mode...

Turn the selector dial to adjust shutter speed.

Hold down the AV+/- button (top-right of rear screen) and turn selector dial to adjust aperture setting.

As for Av mode, this is perfectly normal that you cannot set the shutter speed. Av mode means that you decide on the aperture setting and the camera (not you!) decides on the correct shutter speed.

Hope this helps,

Aperture Priority Mode - an undocumented feature

In addition to the "quirks" of the Landscape and Aperture Priority Modes (neither mode works as documented!)..... The camera also behaves differently in full Manual Mode (it changes the settings, whether you want it to or not to compensate for available light)... At lower Zoom Levels, the camera will adjust the Shutter Speed Only, to try and compensate for available light... For example: with the Camera preset to F5.6 Aperture, and 1/48 sec. shutter speed, the camera will adjust the shutter speed between a range of 1/30 to 1/291 sec, to try and "auto expose" the shot for lower or higher light levels, even though you're in manual mode. At an Aperture Setting of 2.8 and 1/48 of a second, the number of internal steps in shutter speed the camera is willing to take, increases dramatially - for example: shutter speeds up to 1/600 of a second, even though you have the shutter set to 1/48 in manual mode. The camera WILL NOT attempt to adjust the Aperture to compensate for proper exposure in available light (OR WILL IT??).... It depends on your Zoom settings! It won't if your're near to full wide angle, but IT WILL if you are using the Zoom. Once you cross some unknown zoom threshold (it doesn't have to be at full zoom), then the camera begins to change both the Aperture and Shutter speed to compensate for available light, even though you are in "Full Manual", versus Auto Exposure Mode. In Manual Mode, (as in Aperture Priority Mode), the amount of change the camera is willing to make to your settings, appears to be related to a preset number of internal steps, with the number of steps dependent on both Aperture and Zoom Settings, before it gives an EV Warning for Over or Under Exposure conditions.... The type (shutter speed only for wide angle, shutter and aperture for zoom) and amount (number of internal "steps" it takes to increase/decrease shutter speed and increase or decrease aperture), is dependent on the amount of zoom you are using for the current shot.

Shutter priority mode?

s I understand it from what I have seen on the Web, the 3000Z can operate in several modes: 1. Fully automatic (camera select both 2. Manual (user sets both aperture and shutter speed). 3. Aperture Priority mode - user sets aperture and camera chooses correct shutter speed to get a good exposure Apparently there is no Shutter Priority mode (user cannot set only the shutter er speed and allow the camera to set the aperature to get a good exposure). This option is available on the Epson 850Z camera and this seems like a silly ommision to make on a "high-end" camera like the 3000Z.
