If you have a website then you will have to include a number of photos. Unfortunately, not just anyone who has a camera in hand can produce great images. To get photos that will get people interested in what you have to say, you have to own a camera that can take great images and you have to part with several hundreds of dollars to get that not to mention being able to find the exact moments you are looking for. All these are conditions which do not have to give you sleepless nights when you invest in stock photos. Not every photo that has to be bought given the many free options available. It takes a keen eye to know the kinds of pictures to select for the best outcome. Not everyone who wants a stock photo owns a website or wants to post them in such which means you have to think twice before making a selection based on the use you want to put the stock photos into. The contrast of the image is an important consideration to. In the event that there are graphics or even texts which have to be added on the image, be sure to pick low contrast stock photos. This gives the graphics and text a backdrop that is consistent and even.
People stop to check out images that have great colors even if they are not interested in what you are talking about which is why you need to do a color consideration before you come to a final decision. Thus, you need colors that give a visceral response. If the colors are well coordinated, a lot of people will care to look at them and any accompanying messages. There are 7 color contrasts as identified by Johannes Itten which are contrast of quality, color saturation, simultaneous contrast, complementary contrast, cold to warm contrast, light to dark contrast and pure contrast. You should never ignore the contrast of hue and also the contrast of saturation.
It is not common for photos to be posted without a message. Thus, you should pick images which are in line with what you want to talk about. People will get a better insight rather than have questions about the correlation of the image to the message. Consequently, the image ought to be supporting the message and not making people forget about it. There will be more buzz about the photos if they are controversial or loud, garish, a meme, too specific or even recognizable. For photos of actual people, you can decide to have the full body features or part of it, someone who has his back to the camera or looking at it or a shadow.
