How to Save a Photograph in Different Sizes and File Formats Using Photoshop

Week 2 Assignment – How to Save a Photograph in Different Sizes and File Formats Using Photoshop

Goal: Learn to save a Photograph in multiple sizes and formats to serve multiple purposes. Here are the ways you will save your photograph:

1) Large Format “High Resolution Printing” – Set the Resolution to 300 or higher without throwing away pixels and set one of the dimensions (width or height) to 4 inch, 5 inch, or 8 inch. Save the image as a tiff file.

2) Web Format “Posting to the Web”– Resize the image to have maximum width of 700 pixels so that it will post nicely to a forum or blog. You will need to throw away pixels in order to do this. Save the image as a jpg file.

2) Thumbnail Format “Web Gallery Thumbnail or Icon”– I want the image to be exactly 60 x 80 pixels, wide or tall. You will need to throw away pixels in order to do this. Save the image as a .gif file twice, once in color and once in grayscale.

You will need save your image three times and in three different formats. I have created video tutorials that will show you this process. Click on the links below:

Note! – You may find that the resulting tiff image file that you have created is too large to send by email. In that case, you will need to reduce the image dimensions of the tif image in order to reduce the size of the file to a small enough amount to send by email. For instance, today Leasa’s tif image file was a very high resolution and the size of the file was 46,682KB that meand 46 thousand kylobytes which in megabytes is 46MB. That is too large to send through webmail…. How do you lower the dimensions? With the image open in PS Go to Image > Image Size > checkmark “resample image” and “constrain proportions” and reduce the width in either the Pixel Dimensions or Document Size boxes and the height will automagically follow. Dont forget to File > Save. Your file should be smaller now. Make the file under 20,000KB to send by email. To further reduce the size of your files for emailing try zipping them! Right+Click on afile or folder and choose “Send to > Compressed (zipped) folder”.

Turning it In

Send me your 4 resized images (tiff, jpg, and two gifs) , as attachments, to my gmail address dan.alberghetti@gmail.com. The most efficient way is to put all 4 images into a folder, zip the folder, and send me the zipped folder as an email attachment. I will accept the 4 images attached separately too.
