Ok, so I sent some pictures to a journalist to report something I thought was noteworthy. However, one of the images contained my date of birth and other personal information so I blacked it out using markup tools in the Photos app of my iPhone 6 (running iOS 10.3.2). Then, I took a screenshot, then sent the screenshot from my phone to my email account, then downloaded the image to my laptop. Then, I sent that image from my desktop to the journalist.
So, let's say this was the edited original picture (it's in JPEG format because when I sent it from my iPhone via iCloud mail to my other email address then downloaded it on to my laptop from that other email address, it downloaded in JPEG, but the screenshot downloaded as a PNG):
This is the screenshot (PNG format):
Using whatever technique you want, is there any way possible way to see what is under the blacked out parts in the screenshot, because that was what I actually then sent to the journalist.
Thank you for your help!
PS - The images above are examples and not the actual thing I sent! It just says "LALALALALA BATMAN!"
