- All right now, I'll show you how to zoom continuously
or at least to a custom zoom ratio.
And as you can see back on the PC
even though of course everything works the same on the Mac.
Now, Photoshop being Photoshop
gives you a bunch of different ways to do anything.
And that is definitely true for continuous zooming.
And so notice in all, we have five different methods
each one of which I will review, and by the way
they are listed in order of importance.
So the best one of them all is up here at the top.
You can click and hold with the zoom tool.
And so I'm going to temporarily access the zoom tool
by pressing and holding the Z key, like so
and then I'll click
and hold inside the image window
and notice that I'm zooming in continuously
until I release the mouse button.
You'll also notice that you've achieved a custom zoom ratio
in my case at 624%, but your results will vary.
All right, let's say that I want to zoom out instead
then you press and hold this E key once again
click and hold with that key down
and then add the alt key or the option key on the Mac
and you will zoom out continuously.
And then if you release the alter option key
you'll zoom back in
and then if you press and hold it, you'll zoom back out.
So you can go back and forth as much as you want.
Alright, so much for method one
let's turn our attention to method two here
by pressing control zero or command center on the Mac
and notice that not only fits the image on screen
but it also centers the image inside the image window.
And so next we have, what's known as scrubby zooming
which you achieve by dragging to the right
or to the left with the zoom tool.
And so I'll press and hold the Z key like so
and I will drag immediately to the right to zoom in.
If you drag to the left, then you will zoom out.
So there's no need to press the alter option key
on this one.
However, you do need to be aware
that you need to drag immediately.
And so known as if I press and hold the Z key.
And then I click and hold for a moment
before I start dragging to the right or to the left.
It doesn't matter which direction I'm dragging
because Photoshop thinks I want that continuous zoom.
And so if I want to zoom out right now,
what I do is press and hold the Z key
and then immediately start dragging
to the left as you see me doing here.
All right, so that's scrubby zooming
and it's been around for more than a decade now
but a lot of folks prefer a different behavior
which is to marquee the area that you want to zoom.
And so notice if I press and hold the Z key
I changed the occupants of the options bar
the horizontal options bar up here at the top of the screen.
And so notice as long as my Z key is down
I can see this checkbox, scrubby zoom
which is the feature that we just saw a moment ago.
If I turn this checkbox off
and then I still have the Z key down
and I go ahead and drag with the zoom tool
notice that I'm not zooming at all at this point.
Instead, I'm drawing a rectangular marquee,
at which point as soon as I release
I go ahead and zoom on that specific detail.
And as you can see,
I ended up with another custom zoom value
of 182%
up here in a title tab.
And then if you decide you liked the other behavior better
than pressing hold the Z key,
so that you can see this scrubby zoom checkbox,
up here in the options bar,
go ahead and turn it back on.
And with the Z key still down
just go ahead and drag to the left.
Like so.
All right, I'm going to press control zero
commands that are on the Mac,
so that we can see the fourth method
which is available to you
if you have a laptop with a track pad
or a tablet such as a surface book or surface pro
in which case you just pinch
or unpinch
now I'm working on a desktop machine.
I do not have a track pad,
so I can not demonstrate that one,
but I think it's pretty straightforward.
So you can try that one out if you like.
And then finally,
you can press and hold the alt key,
or the option key on the Mac,
while using the scroll wheel on your mouse.
And so this time I don't even have to press the Z key.
I'll just move my cursor over, or I right here,
I'll press the alt key, or the option key on the Mac,
and then I'll scroll up in order to zoom in
or I can move the scroll wheel down in order to zoom out.
And if you don't have an old school scroll wheel
you can do a two finger drag
or whatever gesture works for that purpose.
Now, the advantage of this Alt option scroll wheel thing,
is that you're going to zoom in
wherever you've placed your cursor.
That is not true when pinching.
When pinching as things stand right now
you're always going to zoom
with respect to the center of the image.
All right, so, there you have it
five different ways to continuously zoom
inside of Photoshop,
all of which are going to result in custom zoom ratios.
