Taking photos from a CRT monitor.
Hi guys and guyesses,
I have a Pentax Optio 33L. It's a very modest camera by today's standards with only 3.2 mega pixies. The thing is that I want to take some pictures of images that can only be shown to me on a CRT monitor screen. They are X-rays of my own spine and I'll be viewing the doctors monitor. Because of the circumstances, I'll only be able to take 4 or 5 pictures so trial and error won't cut it. Can any of you camera buffs suggest the proper settings and physical distance I should be from the screen to give the best chance of capturing the images successfully? Ta muchly |

Ta muchly I don't know the refresh rate of the screen, but if it is a NTSC standard (US) it is best to shoot at 1/15 of a sec for an evenly lit photo. Be sure to brace yourself because such a slow shutter speed is hard to hand hold the camera without blur from moving. Be sure to turn off the flash and, if the monitor is small, you may need to get close. In this case, you need to set the camera's macro mode for a clear shot. Also be aware of stray reflections on the screen from lights and such. If you can't control the camera's shutter speed, it will be difficult to get "great" shots from a CRT. John |

However, if the OP cannot do so, he might ask the doc to arrange some way to get the picture/file to him or online in some manner. |

Taking photos from a CRT monitor.
Thanks for the quick help, guys.
I had no idea that the refresh rate of the monitor would make a difference. I tried asking the Doc to e-mail me the pix and he said he would but it looks like either he is to busy, didn't know how or just couldn't be bothered. I have no clue about the monitor except that it is a 15" model and looks older than Moses. |

Ignore my suggestion, unless he has a capture program on his monitor. |

Ta muchly Ask the x-ray tech or the doctor for a CD and stand there and wait for it. I just got a bone-scan CD of my kid and it includes viewing software. If it's on the screen, it's CD-able. Otherwise you're not going to be happy with the results. |

Hi guys and guyesses, I have a Pentax Optio 33L. It's a very modest camera by today's standards with only 3.2 mega pixies. The thing is that I want to take some pictures of images that can only be shown to me on a CRT monitor screen. They are X-rays of my own spine and I'll be viewing the doctors monitor.

Can any of you camera buffs suggest the proper settings and physical distance I should be from the screen to give the best chance of capturing the images successfully? Ta muchly Any distance you can accurately focus at near full-frame will work. The main problem I have found with shooting off TV is that if your shutter speed is too high, you'll catch the electron gun scan lines in mid-screen and get a partial image glitch. I use about 1/30 second, seems to work well. Good luck. In my area, my hospital chain has gone to 100% digital X-rays, and anything else such as CT or MRI and no longer sends "films". Instead, they burn a CD real-time, hand it to me, and it has a self-launching viewer that allows whatever capability the graphics supports, such as pan and zoom, rotate if 3-D, etc. Works great. I ask for 2 CDs, one for the requesting doc and one for me. Too bad yours apparently hasn't gone high tech yet. -- HP, aka Jerry |
