Question about Canon EOS 400D / Rebel XTi Digital Camera

1 Answer

Aperture priority, shutter priority

I am taking a photography class and was learning how to use settings on my camera. I was in aperture priority and added exposure with the exposure compensation button. My pictures turned green even after I returned the meter to 0 using the same button. Then the green went away and when I adjust the shutter speed in Av, or the aperture in Tv, both aperture and shutter speed change as if in program mode. I hope you can help. Unfortunately, I don't have a great teacher and he wasn't willing to help me. I have cleared all of my settings to return the camera to original settings and it didn't help. Thank you.

    I have been inside playing with the camera, trying to get it back to normal. I have taken out the battery as well as the backup battery. I've called canon, can't get it right. the white balance is set to auto. Thanks!

    Actually, the green hue has gone away, my problem now is the Av and Tv settings. When I turn the dial both the aperture and shutterspeed adjust. I have no idea what is causing this. I'm so new to the SLR. I will probably have to take it to the shop.

    Where are you taking photos? inside and/or outside? Is the white balance on the camera set to auto?

You might try overriding the white balance by setting it for fluorescent. Those bulbs are the usual cause of the green hue

How to fix slow shutter speed?


When in Any auto mode or P or A your camera automatically will adjust your shutter speed for ambient light conditions. So if your having issues where your camera is choosing to slow a shutter speed and you photos are coming out blurry then there isn't enough light either because other settings in the camera are limiting light or where ever you are taking photos is poorly lit. Setting your ISO Higher should allow the camera to increase the shutter speed, but will often introduce noise to your photos. The more you play with your camera and learn digital photography the more you'll understand how to make your photos the best they possibly can be. For the time being if getting a no blurr shot is key put your camera in S mode which means shutter priority this will allow you to control and lock your shutter speed and set your ISO to auto this will force the ISO and Aperture to change instead of your shutter speed to get a good photo.

Tip

How does aperture setting affect a photograph?


The aperture is the opening in the lens through which light passes to the image sensor. Changing the aperture setting allows you to control the depth of field of a photograph. When the aperture is opened to a widersetting, (indicated by a lower f-stop number) more light is passed to the imagesensor, creating more shallow depth of field. Closing the aperture (indicatedby a higher f-stop number) allows less light to pass to the image sensor,creating wider depth of field.

NOTE: The aperture setting is one of three primary settings usedto control the overall exposure of a photograph. The other two primary settingsare ISO and shutter speed. Because the three settings work together to produce the overall exposure for a photograph, changingthe aperture setting will require complimentary changes to either the ISO or shutter speed to produce a properly exposed photograph. These changes will bemade automatically by the camera in the Auto, Program, Aperture-priority andShutter-priority modes.

There are two ways tocontrol the aperture setting on the camera:
  • Aperture-priority mode (A) - When shooting in Aperture priority mode (A), you set the aperture value and the camera automatically sets the optimum shutter speed for you.
  • Manual mode (M) - When shooting in Manual mode (M), you control both aperture and shutter speed, which gives you maximum creative control to achieve the exact results you want.

I have a canon rebel T3 . How do I change the aperture ?


On right hand top of the camera there is a Mode dial. Move the dial to Av (aperture priority) then rotate the wheel in front of this dial to set the F stop. The shutter speed will automatically adjust by the light meter.

When taking pictures outside the camera over exposes. Could i have pressed a button that would cause this to happen? when taking pictures indoors the camera takes awsome photos still, but when we go...


Sounds like you set either the aperture to a large small number (large aperture) or the shutter speed to a long value. If this is the case, it should be that in AUTO mode, things work fine, but one of C, M, Av or Tv (custom, manual, aperture priority, shutter priority) modes, the aperture or time are set to something that is good for indoors, but outdoors (where the light is brighter) too much light comes in.

It could also be that the ISO ("film" speed) is set too high for bright light. Again, in AUTO mode, the camera takes care of this setting.

Try each of the shooting modes and see which ones work. If Av is the one that is over-exposed, try making the aperture smaller. If Tv, make the shutter time shorter. If M, make both Aperture smaller and shutter time shorter.

Delay between pressing the shutter button and the camera firing. Canon40d


Not sure what you are really asking here as it would depend on the settings you have selected to use.

For instance if your ISO ) ASA film speed) is set to 64 and you have an aperture priority setting of say 6 then the shutter will go clllllllllickkkkk ( be slow say 1/30th of a second. As opposed to say ISO of 200 and an aperture of 16 the camera will go cliick now if you select ISO 400 and aperture of 16 the camera will clk This is the "sports type setting for fast moving objects ) I am presuming daylight average light for the above
after 4pm or in some shade areas shutter speed can also be delayed and the picture result is blurred due to camera shake at low speeds.
then u need a tripod

Now what have you selected as an amateur snapshot artist?
Day night settings
AUTO
ISO 100 + ........
portratit
landscape
night

Any of these settings on auto will also be delayed depending on ISO and the amount of ambiant light available to the camera. So you need to get to know your cameraq by practice

Some settings ( see manual) suggest using shutter priority to get good pics
Others suggest aperture priority.

It might be better for you to get a basic digital photography book to help you understand and compose good pics ( Digital photography for dummies ( or DP basics)


Hers a tip worth remembering with apertures

Smaller the number larger the hole(aperture)
Larger the number smaller the aperture

larger hole for lower light
smaller hole for very bright light

so experiment with aperture to be familiar on what to select for the degree of light then test different ISO speeds and keep notes.

When you use zoom increase the EV by 1+ and see what the difference is to standard distance

All great fun and learning and now cheaper because you dont have to pay for film or development to see what creative pics you have made!

So perhaps the camera does not have a problem, it just has you, and

you need to bond so Good Luck and ,many happy snappy hours of fun

M42 adaptor


Quite right too. When the M42 adaptor is fitted there is absolutely no exchange of information between the lens and the body: M42 lenses pre-date all of those later developments. Your camera will also be unable to stop down the lens automatically when taking the picture, most M42 lenses don't even stop down automatically when connected to an M42 body.

You need to do things the old-fashioned way. Your camera needs to be set to meter manually, shutter priority mode may also be used. In manual mode you focus the lens as normal with the aperture ring set to the lowest aperture number (i.e.aperture is wide open).
You then make sure that the lens in in manual mode as well and stop down to whatever you want, if the image remains bright enough then you can adjust the precise focus using the hyperfocal principle if you like which takes advantage of the increased depth of field of a stopped down lens.
In manual mode, you then tell the camera what aperture you have set (read it from the lens barrel) and set the shutter speed using the camera's light meter to guide you. If using shutter priority mode then the camera will choose the shutter speed for you.
Check everything is set as you intend and press the shutter.

It all sounds long winded but is exactly how many of the world's greatest photos were taken and soon becomes second nature. You also learn far more about the relationship between aperture, shutter speed and ISO settings and will be able to talk about reciprocity like you know about it!

Manually setting shutter speed and aperture..


http://web.canon.jp/imaging/eosd/eosdigital4/specifications.html

First off, welcome to the world of photography! Good luck and have fun!!!

Like any slr, you have the option of Manual exposure. I'm not familiar w/ modern Canons (I use Nikon). According to this page, however, you also have aperture priority and shutter priority. I'm pretty sure ALL modern Canons have bracketing modes as well (Use this for HDR).

I couldn't find the 450 manual (I'm assuming Canon's web devs are behind), but I did find the instruction manual for the 400 :

http://gdlp01.c-wss.com/gds/0900000357/EOSDRXTi400DIM-EN.pdf

Should be similar, probably w/o some of the functions. Although you SHOULD have a book w/ your camera ;). Read it thoroughly.

Ok, according to the 400 manual, put your camera into Manual mode, then adjust the regular dial to adjust shutter speed. Then, to adjust aperture, hold in the A/V button while you adjust the same dial.

Like I said, may be a bit different. I think the dial may even be digital buttons rather than analog...

hope this helps!!!

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.

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.
