I will start off by clarifying not everything can be fixed in Photoshop so pay attention when taking your image and also not every photograph is 15 hours worth of editing to make look amazing.
One of the common questions I get is how long do I spend editing some of my images in lightroom/photoshop/whatever editing software you use. For me I am typically a 5-15 minute editing person and if it goes beyond that while I may like the image it gets flagged for me to get to at a later time which doesn't always happen. I am by far not a purest and do believe post processing is part of the creative process and helps to enhance images but I am not one that can spend hours on a single image. So figured I would show a few examples and time I spent editing so people had an idea of my workflow and how much I do push some of these images.
My workflow after a session is to download my card using Photo Mechanic which makes copies of all the images in 2 locations, my editing drive and my raid backup drive which sync every night based on editing drive being the primary. I then import into lightroom and start culling through the images flagging the ones I like with 1 star, 2 star for potentials that may need more editing, 3 star for throw away and then once edited 5 star for completed. From there I look at the 1 star images and do quick edits for exposure, alignment and color grading. Then the final touches are usually some curves adjustment and if need to do some spot removals then save and on to the next image. On occasion if the spot removal or object removal is a little more I will pop into Photoshop and do some removals or if I want to really add some contrast pop I do use the Nik Collection of plugins for Color Efex but that is not every image.
As you can see the majority of the time I am not spending a ton of time editing my images after a shoot as I did spend some extra time trying to get as much of it as I can right in camera and the rest are edits I already have in my head for an image.
Wake Up Early. Drink Coffee. Never stop chasing the light and always get out there and shoot.
