IV. CONTROLS AND DISPLAY 13New Picture Stylemaximum aperture. Like theEe-D and Ee-S, it has thePrecision Matte randommicrolens construction withelements of varying size andsensitivity. Two optionalscreens are available, theEe-D grid-type, also good for all lenses down to f/5.6 maximum aperture, and the Ee-S,having finer microlenses than the other two types, intended for lenses f/2.8 or faster,with a steeper-than-normal parabola of focus for easier manual focusing. Becausethese screens have differing metering characteristics, C.Fn.-00 must be set to match thescreen in use.The information display in the finder, below the focusing screen, is like the display ofthe EOS 20D, with the addition of an indicator for FE lock: AE lock, AEB in progress(blinks), Flash ready, insufficient flash warning during FE lock (blinks), High-speed sync(FP flash), FE lock, FEB shooting (blinks), Flash exposure compensation, Shutter speed(if camera shake will occur, it blinks), bulb, FE lock (FEL), Processing data (buSY),Aperture (if unsuitable, it blinks), Exposure level display (Exposure compensation,Manual exposure level, AEB level, Flash exposure compensation, Red-Eye Reduction lampon time display), White balance correction, Max. burst, AF focus confirmation (blinks whenfocus cannot be achieved), MF focus confirmation, No CF card warning (no CF).Finder blackout time is 145 ms at shutter speeds of 1/60 sec. and faster. There is nomirror cut-off with lenses up to EF 600mm f/4L. Mirror lock-up is enabled with C.Fn-12-1.Depth-of-field preview is provided via a button on the lower left front of the camera.Canon’s new Picture Style function unifies settings forimage processing parameters (previously Tone Curve,Sharpness and Contrast) and color matrix (previouslyStandard, Portrait, High and Low Saturation and AdobeRGB) and provides one easy-to-use point of access forthe control of Sharpness, Contrast, Color Tone andSaturation. In the past, some users of the EOS-1D linehad difficulty understanding the effect of disparate settings on final image characteris-tics. Also, some thought that their images looked soft because they did not recognizethat Canon’s default setting for EOS-1 class DSLRs deliberately applies no sharpening.Picture Style makes it simple for users to get optimum image quality by making aselection, which is more or less like selecting a particular film type in the past on thebasis of color characteristics, contrast and sharpness.The first three Picture Styles, Standard, Portrait and Landscape, include Sharpnesslevels 3, 2 and 4, respectively and do not anticipate major post-processing efforts. TheStandard image looks crisp, like a successful snapshot, and the Color Tone andEe-A:Standard FocusingScreenEe-D:Grid ScreenEe-S:Sharp focusingScreenPicture Style selection screen
