Review Affinity Photo • Histogram vs Scopes

[Kodiak Qc]

•



Human's interfaces with the world are their senses, vision is
considered here. Vision is a very personal experience, a real
one… it may well be a matter of life or death.

So personal that some may have different ways to perceive
and / or interpret visual information. This explains why some
will have more or less difficulties with "abstract" representa-
tion of given realities. The histogram is such "abstract" repre-
sentation.

Many of my students had problems understanding the histo-
gram at the beginning. A cool feature in Affinity Photo is the
scope tool… an other "abstract" representation but with a ve-
ry helpful twist. I discovered that, for some students, it is much
easier to understand and the use of the normal histogram gets
like a second nature afterwards.

The gain in the tool panel only adjusts the visual brightness of
the graph

The luminance waveform

The chrominance waveform

The channel waveform

I have a scientific background so I understand basics graph and have always find histograms easy to understand. In the same way as I understand countoured map or color map with a colour scale or anything simple like scales and number of pixel....
Now that your student find wavelenght strengh and shape simpler, that bugs me. I don't get it, I don't even know what i'm looking at!

Now that your student find wavelenght strengh and shape simpler, that bugs me.

From my scientific background and from the years of teaching
and mentoring, I learned that every brain won't apprehend new
concepts the same way and or the same ease.

As a hockey trainer, I experienced kids having no sweat with the
ballistic of any objects but are clumsy moving in a 2 dimensional
space… they can move things in space but had to lear to move
themselves in the same two dimensional space… let alone follow-
ing your teammates and the opponents on the ice.

Accepting their difficulties, my job is to find and use every trick in
the book to overcome learning obstacles as quickly as possible.
