I picked up one of these (a Lenskirt) when I was traveling a lot.
Sits flat in a suitcase and works equally well in any light and gives you a some amount of left/right/up/down motion without introducing reflections. Works well when the glass, in and of itself, doesn't have noise and reflection inducing properties (i.e. multiple panes, reflective coatings).
Thank you. What about taking pictures with rubber hood? Is it only for straigh out the window or I can take it under a little angle? For bigger angles maybe will be better skirt on previous page.
I haven't used either one. According to what Jake wrote about the Lenskirt, it sounds as though you should be able to angle the camera a little providing the glass isn't a double-pane glass. Jake might be able to offer you more info on the Lenskirt.
But I don't know about a rubber hood either. What Jake mentioned about double-pane glass or reflective coatings might also apply to a rubber lens hood no matter whether or not the camera is slightly at an angle to the glass.
