In an age where what you had today will be 10x better tomorrow there are standards you have to keep to ensure our gear is able to keep up with the photographers.
All my zoom lenses are canon L series famous for quality and durability along with my ever changing camera. The resolution and quaintly from cameras is moving so fast I have too as well.
I use Adobe Photoshop CC which is continually upgraded as new versions come.
I normally give a DVD or USB of all the finished pictures to clients in a presentation case. No hidden charges. No worries. Once you have booked and paid for your wedding there will not be another bill to remove copyright logos form you picture. Just all you would expect. All your pictures ready to go!
