Re: Images shot on X-ray film
Thanks!
That clears things up, as someone had posted in the dusty LFF past that they were using X-Ray holders, for imaging with visible light. I could not see how, without heavy modification of a X-Ray holder, and a custom camera.
It may have been done, but not obvious.
What about chemistry, I see the standard was 60 to 90 seconds dry to dry?

Hi Randy, your first question: are x-ray holders safe? By all means Yes. The x-ray particles pass through the holder and nothing remains. Second, do they admit visable light? NO The only way any form of light if emitted is when the particle hits one of the screens. They will emit a Blue, or Green color. Thats why film is Blue or Green sensitive.
Third, the springs push the screens together ( one on each side ) to sandwich the film in the middle. That's why medical x-ray film has emulsion on both sides. My question, what are you refering to as a opaque material? Could you have met the screens, or the film? Don't ask me about what they use now. Its all digital, I'm from the film age. I was talking with a x-ray student about making an immage with modern day equepment. I tll ya, it was like he was talking in a differunt language. Now for your last question about film holders. They are everywhere. With the age of filmless
technology, they are almost reduced to garbage. I was looking for some empty 8x10 box's, and it was extremely
difficult. I did only manage to get one mamo box ( which is not 8x10, they are smaller) and I got one empty 8x10. I felt lucky to get that. If I can be of any help, keep the questions coming. Seattle man...Rde

As I understand it, V700/750 has 2 lenses, one that is utilized for more resolution with smaller negs.
Perhaps we can hack the mask into giving better resolution with 8x10.
And why did they ignore 5x7
You can scan 8x10 any day using array that is normally goes for 4x5. Wont get full negative coverage. Will get it working fine for 5x7 btw.
But do you REALLY need any kind of higher resolution? Even at typical 2400 you get 400mp image. I assure you that on 13x19 print even from that you will see every single bit in moss on tree sides, if focus isnt goofed and you into getting details. You do loose more to scanning array not being able to focus.
I never noticed any pinholes, its kinda funny.. But i dont use any masks anymore.. Used for a while with 4x5 and just gave up.
However this is discussion for other section of forum, i believe :)
Re: Images shot on X-ray film
No I don't need more resolution, but the gearhead in me always wants to fiddle
Loading those crappy masks is a major problem for my crappy hands.
LOL

Dont then. I just tape film to ANR glass, stick glass on 8 pennies and scan :)
Re: Images shot on X-ray film
A practical plan, I will try that that.
Film under or over?

Under. No difference from scanning "real' 8x10 film.

Hi Randy, The time is correct. It all depends on how hot you are running the chemicals. Dryer temp. has to be considered also. Keep the questions coming... Seattle man...Rde
