FOREWORD
Thank you for purchasing the Nikon Autofocus Speedlight SB-26. Used with Nikon's newest SLRs (F5, F90X/N90s, F90-Series/N90, F70-Series/N70, F4-Series, F-801/N8008, F-801s/N8008s, F-601/N6006, F-601M/N6000, F50-Series/ N50, F-401x/N5005, F-401/N4004 and F-401s/ N4004s), it offers you the most advanced and complete system for automatic flash photography available. To get the maximum performance from your new SB-26, be sure to take time to read the instruction manual carefully.
For Effective Use of This Manual
Using this manual is simple. Read the pages with shaded index tabs indicating your camera name. [. . . ] If ready-light  blinks for a few seconds after test firing, flash has fired at its maximum output but light might not have been sufficient. Select a wider aperture or move closer to subject.

Chapter 3 Non-TTL Auto Flash A Mode
Manual Flash i Mode -- Manual Light-Output Control
With the SB-26's flash mode selector at i, you can perform manual flash photography. For manual flash photography, it is important to choose an appropriate aperture and shooting distance to achieve your desired effect. To help approximate these variables, you can use the SB-26's LCD panel and control buttons as a "calculator", or use "guide numbers" (see page 118). To enhance this feature, the SB-26 lets you manually adjust flash output levels from full power (1/1) to 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, and FP1 and FP2. Before proceeding: E ATTACH SPEEDLIGHT TO CAMERA. E USE APERTURE-PRIORITY AUTO OR MANUAL EXPOSURE MODE. E USE SINGLE-SERVO AUTOFOCUS (S or A) OR MANUAL FOCUS (M). E USE SINGLE-FRAME SHOOTING (S) FILM ADVANCE MODE.

Fully depress shutter release button to fire flash. Recheck ready-light to see if it is blinking.
Exposure compensation Exposure compensation in Non-TTL Auto Flash mode is achieved by purposely setting a different aperture value on the camera (actually on the lens in most cases) than on the SB-26. Use an aperture 1/3 to one stop smaller for an entirely dark background (low reflectance). For backgrounds that include a highly reflective object, use an aperture 1/3 to one stop larger. Note that shooting distance range indication / corresponds to the aperture value set on the SB-26 -- not on the camera. In general, you may want to take a series of pictures using exposure bracketing.
If ready-light  blinks for a few seconds after shooting, flash has fired at maximum output but the light may have been insufficient. Reconfirm shooting distance and, if necessary, move closer to subject or select a wider aperture to compensate underexposure.
