I am pretty low tech. But about a year ago, my photo editing program was upgraded and I was forced to explore it. And I discovered the ability to add a flare of light to enhance a photo in whatever spot I desired. I used it a few times including last week when I used it to call attention to the Divine Mercy Image. It neatly reinforced the line in the message that said Jesus' "blessing was reflected in the souls like a flash of light."
I have wavered over whether I should add a disclaimer when I add something to the photo. On the one hand, I think it is a distraction to include a disclaimer; taking away from the impact of the photo and the message. But on the other hand, I don't want to give a false impression that something special or mystical had occurred, when it was really just a photo enhancement.
In this era of "fake news" I thought it was better to be transparent, as they say. So in the future, if I add something to the photo, I will add an indication that the photo has been "enhanced."
