Yes, especially if it’s dishonest and/or illegal. I also do not work on adult content projects and reserve the right to decline offers to do work containing material that is against my personal beliefs and/or religion.
Also, I currently do not do videography or illustrations. (Some logos require some illustration, this may either take too much time or I simply to not have the skill level or tools to do this. Please make sure to tell me ahead of time if you want a specific piece of artwork drawn up ahead of time so I can come prepared and we take the extra cost and time into consideration.)
Even though I can do some photography, I am not a professional. Depending on the quality needed, hiring a professional photographer may be the best option.
