ii) Shutter-Priority AE (Tv) (Relative:- Basic Info on Shutter Speed)
In this mode, you set the shutter speed and the camera automatically sets the aperture according to the lighting conditions. The shutter speed can be set from 30 sec. to 1/8000 sec. in 1/3 stops or in 1/2 or full stops by setting the Custom Function CF-6 to "1" or "2". This Shutter Priority AE mode is effective when use of shutter speed must be given priority. A fast shutter speed can be used to freeze a fast-moving subject, or conversely, a slow shutter speed can be used to blur the subject movement and hence, conveying motion visual effect.

Operation: 1 While pressing the shooting mode selector, turn the main dial until “Tv” appears in the LCD panel. 2 Release the shooting mode selector. 3 Turn the main dial until the desired shutter speed appears in the viewfinder or LCD panel. 4. Press the shutter button halfway to focus the subject and confirm the exposure. The shutter speed and corresponding aperture value are displayed in the viewfinder and LCD panel. 5 After confirming the aperture value, press the shutter button completely to take the picture. If the aperture value is not blinking, proper exposure will be obtained. |
Exposure Warnings (also refer to the warning chart above for further assistance) Although the working range for Shutter Priority AE mode is wide enough for most photographic situations, but it also has its limitation (esp. when a lens (in particular entry level zoom lenses) with slower maximum aperture and couples with low light shooting conditions).

When the number for the maximum aperture of the lens blinks in the display, the image will likely be underexposed. If permissible, turn the main dial to a slower shutter speed so the aperture display stops blinking. On the other hand, when the number for the minimum aperture of the lens blinks in the display, the image will be overexposed. Turn the main dial to a faster shutter speed so the aperture display stops blinking. If either of this still persists, change a film with faster ISO or consider using artificial illumination such as flash. |
Shutter Speed Display (Click for a FULL VISUAL CHART) Shutter speeds are set in 1/3-stop increments. From 8000 to 4, the shutter speeds are displayed as the reciprocal of the actual time values. For example, 125 on the display indicates a shutter speed of 1/125 sec. For shutter speeds slower than 4, actual times are displayed. For example, 0”3 on the display indicates a shutter speed of 0.3 sec, and 15” indicates a speed of 15 sec. The following shutter speeds are available: 8000 6400 5000 4000 3200 2500 2000 1600 1250 1000 800 640 500 400 320 250 200 160 125 100 80 60 50 40 30 25 20 15 13 10 8 6 5 4 0”3 0”4 0”5 0”6 0”8 1” 1”3 1”6 2” 2”5 3”2 4” 5” 6” 8” 10” 13” 15” 20” 25” 30”

Custom Function CF-6 (1 or 2) In addition to 1/3-stop increments, shutter speeds can also be input in 1-stop or 1/2- stop increments. In these cases, available shutter speeds are as follows: |
iii) Aperture-Priority AE (Av) (Relative:- Basic Info on Aperture Value)
In this mode, it is exactly opposite to the shutter priority; instead, you set the aperture and the camera automatically sets the shutter speed according to the lighting conditions. The Aperture Priority AE mode is also often called as the Depth of Field Mode (it is different from the Depth of Field AE (DeP) AE mode that follows after this section. Depth of Field control is one of the most frequently used element in photography. Basically, either you use it to isolate or enhance a subject by using shallow depth of field (such as portraiture) or extends the depth of field by ensuring all important elements in a scene to be pin sharp, for an example, scenic, landscape or close-ups etc..
|
|
Operation:- 1 While pressing the shooting mode selector, turn the main dial until “Av” appears in the LCD panel. 2 Release the shooting mode selector. 3 Turn the main dial until the desired aperture value appears in the viewfinder or LCD panel. 4 Press the shutter button halfway to focus the subject and confirm the exposure. |
The aperture value and corresponding shutter speed are displayed in the viewfinder and LCD panel. 5 After confirming the shutter speed, press the shutter button completely to take the picture. If the shutter speed is not blinking, proper exposure will be obtained. Caution: Camera shake may produce an un-sharp picture if the shutter speed becomes slower than “1/focal length of the lens in use.”

Exposure Warnings in Aperture Priority AE Mode (also refer to the warning chart above for further assistance) |
 |
|
When a shutter speed of "30” blinks in the display, the image will be underexposed. Turn the main dial to set a larger aperture (smaller aperture number) so the shutter speed stops blinking. When a shutter speed of "8000" blinks in the display, the image will be overexposed. Turn the main dial to set a smaller aperture (larger aperture number) so the shutter speed stops blinking.

Aperture Value Display (Click for a FULL VISUAL CHART) Apertures are set in 1/3-stop increments. Larger numbers indicate smaller lens apertures. The following aperture settings are provided in the camera, but the actual aperture range available depends on the lens in use. 1.0 1.1 1.2 1.4 1.6 1.8 2.0 2.2 2.5 2.8 3.2 3.5 4.0 4.5 5.0 5.6 6.3 7.1 8.0 9.0 10 11 13 14 16 18 20 22 25 29 32 36 40 45 51 57 64 72 81 91 |
