When mirroring an image, you are taking the original photo and multiplying it across itself as many times you see fit. In this process, I used Adobe Photoshop CC 2018. The photo I used was taken in September of 2019 using the automatic settings with in the canon. 

Mirroring and image can enhance the impact and or message coming from the the original photo itself. Showing the image repeating, mirrored, can as well take away the impact and or message if done to the wrong image. When mirroring your photo, to make sure it would have a good outcome, and easy thing to look for is lines either complicated to simple would work well. And testing out the effect would work just as well as long as you learn what and what not works for your photo.
