When you are working as a professional fashion photographer, it is not easy to determine that how many shots should you take during one session. As it depends on numerous factors, and each factor needs to be weighed in properly. Which is why I keep the general frame of mind. This allows me to offer quality images in the end. So anywhere between 60 to 100 shots are enough, but you will be offering all of them to your client.
Once you set the idea of finding the perfect image in mind, you have to pair it up with a limit. Or else you will find yourself with thousands of images to choose from.
The reason why you are required to take so many shots is that you need to build an entire collection you can later choose from. As there can be minor issues with the images that make them impossible to use. So when you have around 60 to 100 in different and same postures, you are able to easily pick the perfect one. This is usually the case in one on one sessions, as you have the time and the space to capture the perfect images. Once you set the idea of finding the perfect image in mind, you have to pair it up with a limit. Or else you will find yourself with thousands of images to choose from.
You can easily cover these 60 to 100 images in 50 to 70 minutes and can be on your way in no time. So when you start editing, you can easily cut out the ones you feel are unacceptable, and then move towards different angles, keep the ones you feel might work then start editing the images. Once you are done, you should have about 10 to 20 images to show your client. As they will be the best of the bunch, and enough to help them make a final decision, and no too much that they get confused.
This simple yet effective process has worked for me for years, as it helps me keep a great balance. So I know that I will not have to go through the same shoot again, as I was unable to secure the perfect image. These shots are taken keeping in mind that there could be something wrong with most images, and then you can bring it down to preferences. So this allows you to stay on the safe side. So you do not have to deal with a disaster when you explain to your client that you were unable to get the perfect shot.
If you keep what the issue can bring in mind, you will understand why you need 60 to 100 images from each session. As this is the safe side that helps you secure the best and worst images. The advantage here is, that you can easily delete the worst images, and keep the best with you to edit and pass on to the client. This simple process helps ensure that you and client get the best out of the process, and helps keep your reputation safe. So you can smoothly sail from one client to the other.
