yep, used to have one and it works great!
There's a mass order on now i believe, $10 for one of those :think:
Here's my 2 cents worth....
1. Take a rubber band and a white tissue (No prints hor).
2. Tie the tissue over the flash head. --> Am assuming this is an external flash.
3. Point the flash to the ceiling.
4. Shoot
Idea is to use diffuser and the bounced lighting to get the reflection of the flash off the glass controlled. 1 cent for the rubber band, and 1 cent for the tissue !
Alternative solution.
Shoot at a 30 degree to the side so that the reflected light goes off elsewhere, and then use the perspective shift inside Adobe Photoshop and move the picture back to square.
This one more than 2 cents..... haha....

But it works well.. I tried shooting plane through a glass display window with PC85/2.8 before in my previous previous job. It was superb... just shift until the reflection is out of the image.
Of course, a cheaper way is to use an off-camera flash fired at the correct angle to throw the reflection away out of the view.
I'm also new to flash photography, but I'm just wondering: Won't bouncing the light off the ceiling through a diffuser while shooting straight on cause a reflection as well?
The only 3 solutions mentioned so far in this thread that seem to work for sure are:
1. Get a PC lens and shoot from the side - but erm, not many of us can afford PC lenses
2. No flash. Use a tripod - but we know it's hard sometimes when some bugger in the group start moving
3. Bounce off another surface behind you - but it's dependent on the place, eg whether there is a suitable wall to bounce off.
Seems like the best thing to do is to just avoid shiny surfaces as the background and avoid the problem altogether... :think:

hmm.. so why u not using it now?
actural if you know how a shift lens works, don't need to use it also can, just prepare to waste some image area will do, still cheaper than own a lens so exp and seldom use.
Expensive solution siah....

Precisely. Just a cheap solution via the lens distortion correction with the CS2+ will do isn't it ? Even a perspective transformation works, isn't ? Need a PC lens to do the job, it's like using an axe to kill the chicken.
I'm referring to using a normal lens setting up perpendicular to the "a frame wallpaper", but placing "a frame wallpaper" in one side of the frame, crop it away after post production, don't need to use "lens distortion correction" or "perspective transformation" in CS.

There's a MO selling it for $10. Unfortunately, it ended a few days ago :sweat: Well, i bought my first one from OP at $14
Off-camera cord and make sure the flash direction and film/sensor plane aren't perpendicular (the less so, the less reflection). Yes, it's quite a bit more work, but if you need to use the flash...

oh i see... hmm... what is OP?
Don't want to sacrifice resolution and don't want to PP mah.. ;p But yeah.. PC lens is an expensive solution.. wish I could afford one.. sigh...
OP is is a shop called Orient Photo located in Sim Lim Square.
