Digital Image Resizing

Using Photoshop CS & later

Images should be flattened (no layers) and saved as jpegs.
When saving in this format remember to work in the 8 bit mode for your images.
Resolution of 72 pixels per inch.
Each image should be 1920 pixels wide for landscape format.
Portrait format should be 1080 pixels high.
Your image is now in a worked on state and finalised.

HOW DO YOU FLATTEN YOUR IMAGES?

Go to “Layer” select “Flatten Image” this will flatten all your layers into one called “Background”

HOW DO YOU SELECT 8 BIT MODE?

Go to “Image” select “Mode“, select “8 bits per channel“, and there should be a tick alongside. Leave alone if ticked already.

HOW DO YOU CREATE THE IMAGE SIZE REQUIRED?

Go to “Image” select “Image Size” and a new window opens.
Scale Styles: box should be ticked.
Constrain Proportions: box must be ticked.
Resample Image: Bicubic sharper should be selected
Document Size: do not alter any dimensions here

ALTER RESOLUTION FIRST BEFORE ALTERING PIXEL DIMENSIONS

Resolution: Select 300 if you wish but not less than 72ppi
Pixel Dimensions: Set width to 1920 for landscape format. (Height will be in proportion)

Pixel Dimensions: Set height to 1080 for portrait format. (Width will be in proportion)

NOW SAVE AS A JPG?

Go to “File” select “Save As” a new box will pop up select “JPEG {*.JPG,*JPEG,*JPE}”
enter your file name. Remember to choose the folder where your image is saved to.
“Save In” > (my landscapes) for example

ANOTHER BOX WILL POP UP TO CHOOSE THE COMPRESSION RATE?

Select “Image Options” then select “Quality” enter a value of 8 (go no lower than 6) and set to “High”

To put a white line around your image.

1. To select your image, Click on “SELECT” -> “ALL” or “Ctrl + A”. You will see the ‘Marching Ants’ all around your image.
2. Select “EDIT” -> “STROKE” and in the Colour box make sure you have the colour white.
3. In the “WIDTH” box put “2 px”.

4. Make sure that in LOCATION, “INSIDE” is selected and click “OK”.
