Every photographer has a different editing process, so no one can give you specific step by step as to programs and tools used.
However, here is a basic “workflow”.
1. After the wedding, photographers will most likely put your pictures aside until they have finished editing the weddings before yours.
2. Once they’ve reached your pictures, they have to cull the images. This means, they go through every single picture they took of that day and choose which ones they will edit. This means getting rid of the pictures where someone is blinking, sneezing, lighting is off, or generally look bad.
This process can take a LONG time. Hours and hours for some who really look at each image. I would imagine a lot of photographers take 3,000+ pictures the day of the wedding and of course, produce much less than that.
3. After this, they will edit the images. Again, everyone’s process is different. Some edit each picture individually, removing blemishes, changing to b&w, smooking skin, changing editing out someone or something in the background. One image (at least for me), can take about 30 minutes sometimes. If you’re producing 800 images to your client, you can imagine the amount of sweat, tears and time that goes into that process.
4. Most professional photographers value their products and like to package their cd’s, flash drives, prints, etc. This takes some time putting together as well.
On top of this all, photographers have families and lives as well. So it should all be taken into consideration when looking at how expensive photography is. Because it’s worth it.
