First check: I watch every photos on my camera after each shot or series of shots. And delete right away the ones that are obviously bad. I keep the ones that I have a doubt with to double check them on my computer. This also have the benefit to give myself feedback, enhance the quality of my photos and shoot again to have a good photo. I say this because in the beginning, when I came back home and filtered all of my photos on my laptop, I had to delete bad photos about an interesting subject and it was too late to shoot it again, I lost some good references like that T_T
Second check: on your computer. This is where you save a big amount of time. The first check is a habit to include in your workflow and it only takes a few seconds to do. By the end of your shooting you will end up passing a few minutes to first check your photos. This time investment can save you hours of computer checking afterwards.
Now that I am used to this, I may have a 10% second check deletion compared to hours of more than 50% deletion. Sometimes I don’t even need to delete anything and the pack is ready to be zipped and upload right away !
Don’t forget that it is not about art photography but about giving the right information about a subject. The first layer is like a detailed description of what you want to show. Then, with your skills improving, you can add some of your artistic touch to some of your photos > if relevant ! Because it takes more time and focus to get an artistic photo.
But don’t worry too much about that if you are a beginner, I will develop this topic and share with you my own camera settings + why and how I use them in a future article.
