The Perfect Snapshot
There are a number of ways in order to get your business off the ground, and photography is probably one of the best ways to do so. People need to see what you can do, and sometimes that is as simple as showing them a picture can do so so much more efficiently than text. There are some simple ways product photography can help your business even if your product is as abstract a product as computer services you just need to be willing to try some things you would not try under most circumstances. Just remember that there is a reason for the statement that "a picture is worth a thousand words" and you should do fine.
It is actually easy to use photography to sell a computer services company. Instead of using just screenshots of the sites you develop or of any of your other services, you can use pictures of people looking at the screen smiling with a screenshot edited into the shot you need the picture of the person in order to show someone enjoying the service in order to sell it, and so your pictures should combine your product in use and someone actually using it. The best way is to for the edited shot to effectively be a clearer shot of what is on the screen in the picture little details like that are really effective.
You can also show pictures of people using the software you develop. You can show someone using an app or a website easily enough. You can also show a picture of a product on a website, someone ordering the product, and then the person enjoying the item, and there are ways to create a story using the photographs. Consider how to sell a site that sells blankets You show a little kid with a raggedy blanket and a parent expressing concern at the blanket's shape. The parent goes to a site where she buys a new blanket. The last picture is of the kid enjoying the new blanket. You finish by pointing out that you created the site that allowed her to buy the new blanket.
The same applies to virtually any computer service. If you do web development, you can easily show any potential customer enjoying the site. If you are involved in computer security, then you need to show, pictorially, how your software defends someone's software from viruses and hackers. If you are more involved with computer systems, then actual photos of the computers you use, such as servers and laptops, can be your biggest selling point. The thing to keep in mind that is that no matter which computer services you provide there are a number of ways to demonstrate those services graphically and you just need to figure out a way to do so.
Ultimately, you need to remember that people think visually, and that they only believe something if they can see it. It is your job to create some sort of product photography that allows them to see your service. Do that and you will see sales go through the roof.
