There are lot's of ways you can resize and image within photoshop, but we're looking
at the image size pallet, and in this film we're specifically looking at document sizes.
we've already made a film about how to do pixel dimensions which you're looking at here
on the screen there's a link to it underneath this film
let's just get rid of that and get our mate Photoshop going. Now I've already chosen an image
to demonstrate this with this is one I shot last week for the naked jam company
and I love these pictures they're some of my
sort of current favourites, I'm showing off a bit. Okay here we are.
Let's get out our image size pallet, you go onto
image, image size, click on that and you've got your image size palette
up here are the pixel dimensions which we've covered in the other film
and below that are the
document sizes. what is meant by a document size?
Well a document is a physical thing, you can hold it in your hands. so with a
photograph
with with an image rather we're talking about a photograph aren't we, we're talking about a
print, that is what happens when you turn an image file into a document.
You get a print. Easy isn't it really. This print is five inches wide,
by seven and a half inches high, okay. So seven and a half by five.
that's a pretty standard
image size, there are size by fours and seven by fives and all that stuff
but we are looking at a
seven-and-a-half by five sorry I clicked something accidentally there then, sorry
it's why I got all distracted. Right image size pallet.
let's have a little wander through what all the different options are.
You have a width option, and you have a height option,
and next to the width and height notice there are
measurements or this case is set centimeters if we drop down the little
arrow here
there are different options have measurement you can have percentages
inches centimeters millimeters points pickers and columns
I've been using Photoshop since the 1990s I've never used the point pickle
column
in my life for anything I would imagine that something with the printing
industry press industry newspapers magazines and things like that I never
use them as photographers and we really need to accident
book getting any brain space likewise percentages I have never used the image
size palette
to increase or decrease the size and respond percentage but maybe you would
if you wanted to use that you just click on it
uses a hundred to increase it by 20 percent you just type in
120 and there you go
and notice that Photoshop also increase the height by 120
at the same time that's because these two little boxes the link
I'm gonna go back and do what I just did can go back two inches the Kings
easy to demonstrate this with proper measurements you
that's wrong and i'm looking at the wrong time it's dark and bright
image size palette inches
happy days were back right in this image
is seventeen-point a 67 inches by 11 points
867 inches families with 18 inches across the long edge that's quite a big
print business ass
that sorta saudis hassle of by changing
the width and height on the left you can change
the size if you're image so let's say we want to change that
to 12 inches wide I just type in 12
you notice that the high has changed with it
it now says seven-point 97 that's made it pretty much
12 by has net that's because Photoshop
is keeping the aspect ratio that's the shaker the pitcher
constant because this little chain here is being displayed
just undo what I did the reason that chain is being displayed is because the
Slingbox here constrain proportions is take
by and take a that chain disappears and now if I change the width
212 you see the 11 has remained the same it hasn't changed the height
in proportion to its if I apply that all the sudden
my picture goes really well the square and everything it's a bit tall and thin
it's been funny shaped that Sunday
right image size
palette he/she is let's retake constrain proportions and bring back by Mikes
then she's underneath this we have
resolution next to resolution
is another little drop grandma the option of pixels per inch or pixels per
centimeter
we work in inches on the stick with inches but what does that mean 240
pixels per inch
think pixels as dots when you print image
your princess squirts loads a minute little goals whoever the paper they're
all very very close together
you not see them as does he see them as a cohesive whole is a lucky shot
image because you're viewing them from over here
if you don't have enough dots per inch then they gonna be too far part new
images gonna go soft insole be
if you watch the pixels film know that monitors the internet work on 72 dots
per inch
because that's all the internet all monitors can display and so your
pictures that love you mp3 show up there
but if you try and print image seventy two dots per inch
what will happen is all end up with something the source would have jagged
ian is broken apartment blocks in his pic silly
with not very nice to talk see need to make sure you have plenty pixels per
inch
dots per inch the best resolution rule of thumb this is
for printing would be 300
thoughtful pixels per inch have you got plenty have a nice shot
image I think he noticed as I change that to 300
the filesize change this is up here it's 54.6 megabytes in any brackets was
thirty 4.9
that's because as we've added some resolution so the file sizes Gopika
and this is really pretty good way of making of our size bigger if you sending
something to
to a photo library they may have a minimum requirement fifty or sixty
megabytes or something
by increasing the resolution a bit you are increasing the file size but you're
not losing image quality
underneath hey we have a little take most called scale soil styles
can speak just leave it take an honest tell you what it is mostly because I'm
no idea what it is
all I know is that Paul Williams my printer who is really really up on this
kinda stuff that just take it you don't need to know what it is
and the results I get a Brit so there we go they detect job done
much the same with three sample image there are different options down here
I use I'm by cuba because again Paul said they were easy to get the best
results from a and/or day so there we go down all the others are you need to know
either
we need to know is what to do to get a great image
so we were all set up we've got our constrain proportions amigo 300 pixels
per inch or docs but
dots per inch let's change the size the image Mike French away
well now on their is a seven-and-a-half by for my business select
make this one the same let's make the hike the with
7 point for life and Photoshop is my
almost five going the other way so let's kick okay they
coyotes resized a file hit the Go button prin
now I'm any printing on plain ordinary papers on imprint anything here talk
was he carrying him a choice it just on folks who think we having on best photo
because it was just a horrid
K click OK asking we stopped my printer
seven-and-a-half by 5-inch image will pop out on a piece of
84 paper you use improperly get paper you calibrate your monitor new printer
together they should have a really lovely print
on not going to know that
right on have a cover table at Randalls after the printer
is we all know it gets take a while don't think Jenny to speak this
or cut it out altogether I don't like
they have it seven of age
by 5-inch print on a sheet of a4 paper
on foot a print that the guy we got these cut edges of
job done not be doubly now I said he stood for checking
image size as well the night because
there are other sizes which in knots a the same
aspect ratio is dates for example
10 by a is one of the most popular frame sizes
but if we use season 2 I've done if we use the image size palette to resize a
10 by eight
it one work because if I put
think she's my apt 302 gain and I change that
10 inches wide the
six-point six heart not 8
that's because to keep the aspect ratio the same
I it has to be 6.6 if I and take constrain proportions a manually enter
8 well you work
Barack it would be a horrible shape when I apply it
is remaining again it's comical boxy and bit taller than it should be
if you want to resize and image to something like ten by eight
best weight doing it is to use the crop tool
if I just here he go click here status there from when I was practicing gonna
clear
right you go we want to wait to be ten inches or typing
10 space I N for inches
and then the high we wanted to be 8 space
I N finches and all resolution
heads up he knows exactly its 300
pixels per inch we've got enough dots per inch
now we have to do is to you see the curses got a little gunsight on handle
arundel crosshair thing if I'm track that
across the image and notice it doesn't matter where I put the cursor
it's keeping this little reveiw marching ants here
in the aspect ratio attend by a two-vote just drag it straight across from that
guy
this area has gone dark because he's going to cut back piece of
in order to make it 10 by a 10 ways to the pain in the neck to have a group of
people because it means that
if they filling the frame it cut some of the end
let's say you don't want making jam in the middle well
you can just Trank you crop around a little bit and put it we want a long one
about
there like that then mayor's press Enter
and I will crop the image to 10 boy i if you wanna check it
or something to an image phone told you is 10 by a
we gonna day's going to our image average size
bring out the image size palette and look in the document size: area
combat inches and look we have a lovely 10
point eight-inch print all ready to go
so there you go image sizes using the document size:
a area the mid-size palette that I use it and that's what it does
I strongly recommend you go okay if I feel about gun play with it
