iv) Depth-of-Field AE () This shooting mode is NOT possible when the lens focus mode switch is set to M. Make sure the focus mode switch is set to AF. Next, this mode is NOT available on the Pellicle-Mirrored Canon EOS-1N RS model. (Relative:- Basic Info on Depth of Field)
For users who often engages in depth of field related photography, other than the standard Aperture Priority AE featured earlier, Canon has another alternative consideration. I think the first Canon SLR which deploys with this shooting mode is the 1987's Canon EOS 650 QD (but it was not available on the more serious Canon EOS-620QD introduced shortly after ) . This is an all-original Canon effort which remains today exclusively found on selective Canon bodies; so, for new users of Canon system, you may find it a little confused with the differences between the Aperture Priority AE (Av) and this uniquely Canon idea of Depth of Field AE (DEP). Like with the EOS 5, if a focusing point has been manually selected by the user, Depth-of-Field AE operation is the same as the EOS 650, with priority given to obtaining sharp focus between two subject points specified using the selected focusing point. In automatic focusing point selection mode, however, the center focusing point is used for Depth-of-Reld AE operation. In practice, this mode places everything between two freely set points in the foreground and background within the zone of focus, effective for making sure everyone in a large group picture or everything in a landscape photo is rendered sharp. After you designate the near and far points in the scene, the camera automatically sets the optimum focus position and the aperture necessary to achieve the required depth of field, then sets the shutter speed to achieve the correct exposure. The near and far points can be designated using the selected focusing point in manual focusing point selection mode, or using the center point in automatic focusing point selection mode. But it is not possible to use two different focusing points to specify the first and second subject points. So, basically it automates depth of field control and eliminating the combine use of depth of field preview. A slight draw back when compare to using conventional aperture priority AE is, it takes a little extra time to do it but it yields more precise results, that is all.
Operation:- Using Manual Focusing Point Selection Mode:- 1. Select the desired focusing point. 2 While pressing the shooting mode selector, turn the main dial until DEP appears in the LCD panel; 3 Release the shooting mode selector. 4. Place the selected focusing point on the nearest point you want in focus (point 1), then press the shutter button halfway. When the in-focus indicator and dEP 1 light up in the viewfinder, remove your finger from the shutter button. 5 Place the same focusing point on the farthest point you want in focus (point 2), then press the shutter button halfway again. When the in-focus indicator and dEP 2 light up in the viewfinder, remove your finger from the shutter button. Points 1 and 2 can be reversed if desired. 6 Compose the picture and press the shutter button halfway to set the aperture and focus for the designated depth of field. The correct aperture value for the designated depth of field and the corresponding shutter speed are displayed in both the viewfinder and LCD panel. If you remove your finger from the shutter button, the display changes to dEP + aperture value. The exposure is determined immediately before the shutter is released. 7 Press the shutter button completely to take the picture.
Exposure Warnings in Aperture Priority AE Mode (also refer to the warning chart above for further assistance)
Using Automatic Focusing Point Selection Mode In automatic focusing point selection mode, use the center focusing point to designate the near and far focus points. Using AF point for this mode is easier, using Manual selection of focusing point is more complex and slower. The basic procedure for Manual Focusing Point Selection Mode applies to auto mode.
v) Manual Exposure () Just turn the Main Dial to set the shutter speed and turn the Quick Control Dial to set the aperture.
Many may think since modern days SLR has incorporated with so many advance automatic shooting modes, why would anyone want to revert back to slow acting manual control. Forget about the purist theory as in the first place buying an electronic SLR does not serve his primary objective (if this is the main purpose of investing into a SLR camera). However, manual exposure control is useful when one wants to temporarily suspend any of the sensitive automated exposure process, for an example when if you metered a subject with ever changing lighting condition behind which would certainly keeps on affecting exposure reading of a fixed metered subject, manual meter would come in handy to lock the exposure for series of shots. Anyway, this mode lets you set both the shutter speed and aperture. Well, I don't intend to write off all other possibilities in using Manual control of exposure for photography, so this mode can also be used when you need complete control of exposure for creative effects or when using a handheld exposure meter, for another few instances in possible applications.

The main dial sets the shutter speed and the quick control dial sets the aperture. Manual exposure operation is basically the same as on the EOS-1, with the addition of a custom function (CF-No. 6) that allows shutter speed and aperture values to be set in 1/3-~top (custom function setting = 0), I-stop (1) or 1/2-stop (2) increments. The indicator bar ( ) at the vertical LED display shows exposure variations in exposure changes or adjustment.
<<<--- A simple illustration with three possible scenario of the status bar, the CENTER shows a theoretical good exposure; the left is OVER exposure and the right LEDs signifies UNDER exposure.
Operation:- Using the Cameras Built-in Meter 1 While pressing the shooting mode selector, turn the main dial to the left or right until M appears in the LCD panel; 2. Release the shooting mode selector; 3. Set the quick control dial switch to "I" position at the rear of the camera; 4. Turn the main dial to the desired shutter speed and the quick control dial to the desired aperture.
Note: -The optionally available Command Data Back E1 is not equipped with a quick control dial. When using the Command Back E1, set the aperture by pressing the exposure compensation button and turning the main dial;
5. Press the shutter button halfway to focus the subject. M and the exposure values are displayed in the viewfinder. The exposure level indicator at the right of the viewfinder shows how far the current exposure setting is from the exposure value metered by the camera; 6. Set the shutter speed and aperture value as desired while watching the exposure level display, then press the shutter button completely to take the picture.
Custom Function F5 This custom function lets you switch the functions of the main dial and quick control dial.
Custom Function F6 In addition to 1/3-stop increments, shutter speeds and aperture values can also be input in 1-stop or 1/2-stop increments.
Custom Function F11 This function lets you set the aperture value using the focusing point select button ( ) in combination with the main dial. The operation method described in step 4 can be changed in six different ways using various combinations of custom functions 5 and 11
Both the flash exposure modes in the Canon EOS-1N are essentially be categorized under automatic exposure control mode rather than referring them as a feature, so, they will be discussed first prior to other secondary supporting camera functions in supporting various shooting modes.

vi) A-TTL (advance-TTL) Automatic Flash Exposure ()
vii) TTL Automatic Flash Exposure
vi-a) Flash exposure compensation and setup procedure:- Flash exposure control in the EOS-1N can also be categorized as part of its Exposure control system. The topic has been group under the FLASH PHOTOGRAPHY with EOS-1N section (if not, I will not have another section there right ?
Other Supporting Functions for Auto-Exposures: - From ambient light to flash, above has outlined various possible functions and setup process of various exposure control modes available in the EOS-1N. However, unlike those mechanical days of SLRs, photographers can only use of a few methods such as altering ISO, adjustment of mid aperture diaphragm etc. to fine tune an exposure. When auto-exposure started to incorporate into SLR design, a few gadgets were provided to permit photographers to adjust camera set metered reading during an auto exposure process. Exposure compensation and AE-Lock were two of the earlier common feature in any AE-SLRs. Today, as cameras are getting more sophisticated in design as well as incredibly complex with its various high performance functions (such as multiple options in autofocusing, exposure control and metering options etc.) - each of these, works singularly or in combinations has helped successful delivery of well exposed image such an easy breeze even for novice. However, individual interpretation of a GOOD exposure can be a very subjective matter. So, manufacturers designed a few other special commands in helping photographer to further fine-tune or override camera commanded exposure reading to meet respective individual preferences. MOST are relatively easy to use but some may require good visual memory of whereabouts of buttons, dials and in particular, the operating sequences. Anyway, if you have just bought a Canon EOS-1N, try to familiarize basic AE-aided features first before attempting to go one step further on other variables.
