glass reflection in photo
Hi
I am very novice user of photoshop, I was wondering if someone can suggest some photoshop filter or techiniques by which i can reduce the glass reflection on the pictures, I took the pictures while in a car with car window up and there is a white reflection of a t-shirt , is there a way that I can set some kind of noise threshold to remove that white reflection, thanks the link to the photo is http://pg.photos.yahoo.com/ph/sakcee...d&.dnm=6fb5scd... |

You can't accomplish this in photoshop afterwards. Often a polarizer is bad news for the safety glass in cars - it shows all sorts of stress things in the glass. I have seen some really strange patterns when viewing auto glass through a polarizer (spots and other strange things). While post processing is very tough, one thing that works fairly well is either a black cloth or black shirt to make it as dark as possible behind the window when you are taking pictures from a vehicle with a window you can't open (the airlines frown on my opening the window at 37,000 feet for some reason). I use that when I can when shooting from an airplane and it usually works fairly well. mikey |

I always set my camera to 'landscape' mode which sets focus to 'infinity'. Saves time, and eliminates any negative effect the window coating may cause. The problem of reflections can be minimized by holding the camera as close to the window as possible. Polarizers aren't recommended for pictures through stressed, or safety glass. |

One comment on Ron's statement - "holding the camera as close to the window as possible" means close but NOT touching the window. Unless the vehicle is completely stationary, if you touch the window, you immediately pick up any engine/road vibration in the camera. Close is close WITHOUT touching. mikey |
