People appreciate more the graphical ones than the textual; the ones that are more graphic and has a lot of designs would always get a second glance. Make something like a photography business card that will serve as a small version of your work.
Try to check out those stuffs that have a good appearance just like books that were bought by individuals because they have covers that are fascinating as well as stores that have logos and signs that really look fascinating too. It would seem to be not a right one but truthfully people base their judgment with the business cards. Well, if you have business cards that showcase great images they would probably think that you do great at photography.
You have to make sure that you know what you are marketing. You can make a design for different business cards that target different market. You can also design something that will cater to the public for all occasions. You can do something like sophisticated ones if you are meeting people in the likes of Vogue or an edgy one if they are from MTV.
Be very careful with the image or picture that you will be using or portraying because the business cards will do a lot on that stuff. Choose something that will really showcase of who you are; something like an icon or design of who you are. Remember that you have to stick with one image because it is very public and can be confusing to the people too.
Also, if you are known already for a certain type of work, you can put it in. Most often, the work is more popular than the artist but if you are going to be identified with something specific, it will increase your chances of getting a job.
Also, you have to be careful with the fonts you will be using so be mindful about it. Certain fonts have different designs like some are for the ladies only. You got to consider what is appropriate with the style you got. This way, it would be a great stretch for you. Keep in mind that if you have an eye for photography, you will indeed have an eye with overall visual appeal.
You got to have design elements that are eternal. There are themes, fonts and others that may look good for now but will not look good in years from now.
