I put a few of them through this website: http://imageedited.com/ It said "probably". The website is very good at detecting Photoshopped images, and "probably" has always meant "yes, it's Photoshopped" in my experience. (I chose pictures from their website, not the google photos)
photos the company posted were Photoshoped.
No none of my photos are photoshopped or filtered.
