NightVision and FlashLight for the TH55

[Streamhawk]

Hi guys,

Yesterday I saw in the web a lot of free apps that offered mirrors, flashlights, and a red light for night vision, but all these apps where for 320 x 320 screens. When I took a look at my TH55 I saw that when it's turned off it works great as a mirror so no problems there. For the Flashlight and Night vision (red light) I made Jpegs in 320 x 480. The red light is suppose to not hurt the eyes that are already used to the dark. This is not a hot addition to the Forum, but it may come in handy one day. ;)

I made two Flashlight Jpegs, one is completely White (so you may not see anything) and the other has a black background to make the beam of light have a little more focus.

What's wrong with just leaving the Clie on maximum brightness on the default launcher? It's extremely bright in a dark room!

I agree --- I use mine as a flashlight all the time with brightness at 50%, it works very well.

so.. maybe a dumb question.. why we want red light for night vision if we have white light? isn't that using your white jpg for white light will let you see more?

thanks

Hi guys, I was just trying to help out. Sorry if this upset you, BTW Softech the red Light is for when your eyes are adapted to the dark, that way you don't hurt your eyes or anybody else's that are in the dark with you. I guess that the only real one you could use is the red light, sorry for the other flashlights.

Even the red jpg will destroy (my, what a harsh word) dark adaptation as it is a white backlight providing the light. Red on a computer screen, even with applications that claim to be dark adaptive, are still lit with white backlight. Red LED flashlights and weak white flashlights with red gel/plastic over the lens are the only real ways of protecting dark-adapted eyes.

This is from extensive testing. I help operate an public observatory and have many hours behind the telescope. We cover our screens with a thick (1/4 ") piece of red plastic and tape it in place so there is no escaping white light. For laptops and palm-based computers a piece of red transparency works satisfactorily. Apart from that, darkvision is compromised.

Getting red transparency works great with the TH55 and I use it all the time when observing with my scope when not inside the observatory.

Anyway, just my 2 cents worth...

I think this images are a clever solution, myself.
