I've been using my Sony a7iii for about 4 years. today I took some black and white and sent them to my phone with bluetooth the pictures are in KB I want to make a 30 by 40 print so I pulled my SD card and put in my MacBook and the pictures show on the bottom bar in black and white but when I send them to light room the pictures are in color and I can't update my camera has this happened to anybody ?
