What type of photo do you need?
To find the right photo, use your search engine skills. Most high-quality stock photography websites have sophisticated search tools that reward specificity over generality.
For example, if you’re trying to find a stock photo of people eating dinner, figure out how many people you want, what type of people you want in the shot, and maybe even where you want the photo to take place. In this example, the basic search term “people eating” might not get you where you need to go, while “three women eating dinner at night” might get you a better series of results. Experiment until you find what works best.
How will you use the photos?
If you want to drop stock photos into an existing design template, the main consideration is that they are sized properly and are high resolution. There’s nothing less professional than a flyer or advertisement that is pixelated or grainy.
Often, however, stock photos are manipulated or modified by a graphic designer in applications like Adobe Photoshop, so when you’re selecting a photo, this is important to keep in mind. For instance, a modified background is much easier to work with if the photo has a single color or is shot on a green screen.
What’s your budget?
The final consideration for using a stock photography site is a simple one — the budget. Different stock photography websites have different price packages depending on what you’re looking for and how you’ll use the image. Some are priced for the individual photo while others charge subscription-based fees. Still others have free or public domain images that are available under Creative Commons licenses. Determine how much money you have allocated for a project and the types of photos you can afford. It’ll help you in the long run, especially if you’re working with tight budget restrictions.
