Focus Peaking and Manual Focus
The Focus Peaking feature is a great aid to get the focus right as it will
highlight the areas in the Live View feed that has high contrast and are thus
likely to be in focus. It will update continuously as you adjust focus manually
on the XT Camera. This feature is especially useful when you have zoomed
into the image.
You enable
Focus Peaking
by swiping in from the right side of the touch
screen while in Live View and toggle the feature on by tapping on
Focus
Peaking
icon (it looks like an eye).
You can change the
Focus Peaking Threshold
by long-pressing on the icon.
Then adjust the threshold by sliding the finger on the bar.
Here you can also change the
Focus Peaking Color
from the default green to
a more suitable one.
Note that the feature looks for high contrast areas, so smooth zones like skin
tones or a clear sky might not be highlighted, even if that part of the image is
within the depth of focus.
Using Auto Gain for Automatic Brightness
The Auto Gain feature will optimize the Live View image to show a bright and
even exposure of the subject regardless of what exposure settings you have
set. This is desirable when you need to check critical focus or the composition
in dim light, for example when you are working with the modeling light of a
flash system or out shooting at dawn. This is similar to how the Live View
image was displayed on the IQ3.
The Auto Gain feature works as a toggle, making it easy to switch back and
forth between Exposure Simulation and Auto Gain on the set. It is activated by
swiping in from the left and tapping on
Auto
. The IQ4 will now analyze the
image and adjust the brightness automatically. Note how the Info bar at the
bottom will now display
Auto
. Swipe in from the left and tap on
Auto
to turn
Auto Gain o
ff
again if needed.
Auto Gain is also referred to as ViewFinder Mode in the IQ4 menu system.
Adjusting the Auto Gain brightness
If the calculated automatic brightness on the screen is too bright or dim, you
can finetune the gain manually. Swipe in from the left and tap on the
adjustments icon. Then tap on the slider and move it to readjust the
brightness.
Swipe in and tap on the adjustments icon to dismiss the slider and accept the
change.
Using Auto Gain with open or shooting Aperture
When using the Auto Gain feature in Live View, you can choose whether the
lens aperture should be fully open or closed down to the shooting aperture.
Using the aperture closed down to the shooting value will let you evaluate the
real depth of field and sharpness throughout the image. Using the aperture
fully open instead can make it easier to adjust the point of focus accurately. It
will also let more light in, giving you a Live View feed with lower noise in very
dim lighting.
You set the aperture behavior by swiping in from the left and long pressing on
the
Auto
icon. Then select
LiveView Open Aperture
in the menu and set the
function to
Enabled
(fully opened aperture) or
Disabled
(shooting aperture).
You should be able to hear the aperture open or close on the lens as you
change the option, providing that your shooting aperture is not fully open.
