Nokia 1020 A00014473 用户手册

Nokia Pro Camera lets you take full control over your 
camera with a set of manual controls normally only 
found on advanced SLR cameras. Naturally the default 
for all controls is ‘auto’ but the UI is very intuitive and 
it helps you and encourages you to start experimenting 
with the controls so that you can become a better pho-
tographer.

EV  stands  for  Exposure  Value  and  it  influences  the 

brightness of the photo. The default value is 0 which 
means correct exposure for most situations. If you in-
crease the EV it will make the picture brighter and you 
can see it in the viewfinder. This is great, for example, if 
your subject is in the shade, and you need to over ex-
pose. And if you slide it down, your photo will get darker, 
which is good if you want the sky to be dark blue. This 
is useful for example when you are at a concert and the 
stage is extremely bright compared to other areas. The 
EV can also be used creatively to make artistic-looking 
washed-out photos or silhouettes.

Shutter speed is also called Exposure Time, and defines 

how long the shutter is open to expose the sensor to 
light. You can set it to as low as one sixteen-thousandths 
of a second (1/16000s), which is good if you have a lot 
of light and want to freeze the motion. By setting the 
time all the way up to four seconds, you can capture 
amazing night shots like seeing the light streams from 
car lights.

iSO is how much the signal from the sensor is ampli-

fied. This is good when you don’t have much light, but 
high ISO-numbers can introduce noise in the picture. In 
a dark situation with movement, you typically want to 
increase the ISO, to amplify the light, so that the camera

does not have to keep the shutter open so long. 
Typically in daylight ISO 100 works well, and you might 
want to increase ISO to 800 in dark situations.

Focus: With focus you can set the focal plane manual-

ly from 15cm to infinity. If you lock it to infinity most 
things beyond 10m are in focus. The manual focus is 
great if you know how far away your subject is, and want 
to take a picture quickly, without having to wait for the 
AutoFocus  (AF).  Manual  focus  is  also  useful  when  you 
shoot close-up or macro shots, and when you want to 
lock the focus to a point the AF is not able to focus on.

WB: White balance controls what is white in your picture. 

What looks white depends on the light sources in the 
scene and sometimes you might prefer warmer or cold-
er tones than those the camera automatically provides, 
so you can experiment with the manual settings. The 
Lumia 1020 includes settings for cloudy, sunshine, fluo-
rescent and incandescent.

An alternative way to access the controls is by sliding 
the digital shutter key on the screen to the left. This 
gives an overview of all the controls and their value. You 
can swipe the shutter key a second time to the left to 
reset all the values to auto.

To help you get the best shot, the Pro Camera UI also 
offers guidance. The camera will show you when you are 
about to over- or under-expose, by showing a value be-
tween -3 and +3 in the EV field on the top right. Some 
values of ISO and Shutter speed might result in noisy 
images or a lot of blur due to hand-shake or movement. 
This is indicated in the dashboard by an underlined val-
ue. You can also see what value the camera is going to 
use in the auto-mode.

if you are in a situation where you don’t want to disturb 
anyone with the light from your phone.
