Always include sheets in your portfolio that you can hand out, as well as a business card. Something with nice stationery [as long as it's not busy and covered in designs] that has your name, phone number, and email address at the top [and website, if you have one], includes your booking and pricing information, and a list of events that you've done. Things like weddings and proms are a lot more important than people realize. Maybe you've worked with a photographer, achieved success online [with youtube or various other notable places] and for portfolio pictures, natural lighting works great. Make sure you get good, focused face shots, and for elaborate detail work, closeups. I always take one of the model with her eyes open, and with her eyes closed, focused on the details. Clean lines and soft blending leave an impression. If you're taking the pictures yourself, take them on a high resolution with proper light settings, and if your camera has a vivid colour option, use it. It also helps to have a micro function for closeups to keep them from looking blurry. I wouldn't carry more than 25 photos of different looks in your portfolio at any given time, and switch out which ones you use depending on who you show it to. If you're showing it to a bride, she would like to see natural makeup and simple, pretty elegant things. If you're trying to get hired to work with a company, include more avant garde and unique looks that demonstrate the best of your talents and what you're capable of. Just make sure what you're showing is going to suit who you're showing it to and capture their interest. And just a tip -- the side of a building is always an attractive backdrop. Whenever I photograph models, I go down to the docks and use the sides of the cute little shops as a background. It works beautifully.
