Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
Before we actually begin to size our images, there are few things that we need to consider and we need to wrap our brain around screen resolution. So I want to do that in this movie. In particular, I want to look at sizing our images for viewing on a website and then sizing our images for e-mail. Now one of the things we do know is that there is still majority out there that use a resolution on their monitor of 1024X768. So typically, we need to keep these numbers in mind. One of the things we have to know about these numbers is that we actually don't have all of these pixels and here is why? On a Mac you have a dock down below, on a PC you have your Start menu, then the top of the browser takes up a certain amount of space as well.
We also have a scroll bar in the right that can take up space. So, we actually don't have all of these pixels, we don't actually have 1024 across and 768 at top, we have a little bit less than that. And so just as a way of creating a reference point, let's talk about niche.com Now Niche is a company that pushes the envelope yet they still need to have a really broad reach. So what do they design their website and for their home page? Well the home page is 950 pixels across and 570 pixels top. So that is a pretty interesting numbers.
So one of the things that these numbers help us know is that our images are somehow going to have to fit within those dimensions and typically you don't want to go taller than 585 but even that would be way too big. So what are some different sizes that we can consider? Let's open up an image for a second. So here we have an image inside of this space. There are a lot of different considerations. Sometimes it's nice to have a little bit more negative space around the image so our sizes went down. In this case we have some breathing room, I'll undo that. Perhaps we want a larger image, what numbers can we go with? Well we know that they need to be at least less than, approximately 900 wide and at least less than 585 tall.
So a good starting point, we've really large size image on the web, which would be about 800 wide by about 525 or so tall. Now that's a really big image in this viewing area but that something we could work with. Well then let's consider if we are going to e-mail someone an image. Here I have a quick screen grab of my e-mail client, I use Entourage, there are a number of different e-mail programs out there and a lot of us use web mail like Gmail or something like that. Well then let's take a look at sizing your images down for sending e-mail.
Let's say I want to send my mom, a photograph of my daughter Sophia because she loves getting photographs of Sophia. Well, I want to size my image down even further, if I size that to 800 wide. Well, it just would be too big. There will be some scrolling involved. Now I want her to be able to see the image inside of her e-mail client. So in this case I'm going to size this one down to about 500 or less wide. Well the intent of this movie is to just begin to help us to think about screen resolution and how that effects, how we size our images. Enough on this, let's actually size our images and we'll do that in the next movie.
