35mm Adapter Static Aldu35

Frank Ladner · February 6th, 2004, 11:27 AM

Hi Alain!

It is a glass uv filter, for sure, but come to find out I quit grinding too soon.

You were right about the grinding time! After comparing your footage to mine, I realize that although my glass appears very fine grain, it needs to be even finer. So, I have taken it back to the ol' grinder for another round since then.
It is looking better and better. I have ground it three separate times and will likely do it some more. Now all I need is a condenser to concentrate the incoming light onto the glass more evenly. Also, I will still likely need that achromat macro adapter.

Thanks for your help!

,Frank

I haven't, but I'd be interested in reading what you find.

I just got off the phone with a place called the rock shed http://www.therockshed.com/grit.html .they have 1000 grit aluminum oxide just placed a order 4.50 a pound
2 dollars shipping said he would ship monday morning first thing ........... my order with sis .it took them one week to tell me it won't ship until march and 15 dollars shipping and handling

Good deal Richard! I think I will place an order with the rock shed too

James Ball · February 8th, 2004, 01:07 PM

Rocks are polished with 1000 grit.

You roll and roll and finally they come out mirror smooth. So at some point your fine grain will look like polished glass.

If you look at a polished glass surface under an electron microscope it looks like you are looking at a gravel parking lot. So at some point more is not better.

LCD Screens. Jameco.com sells 4" LCD screens that you can separate the LCD from the light source behind it. Some LCD PC monitors are the same way. Essentially all you need to do is physically flip over the LCD and or invert the panel.

fliping the panel 180 LtoR would of course invert L to R rotating 180 degrees would invert top to bottom.

You don't need to do anything "ELECTRONIC" except perhaps lengthen the conductors

Some LCD panels have an integrated light source that would be difficult to use.

I have to ask why someone would take apart a LCD in HOPES of fliping AND mirroring the image when you can just BUY one that does that at the touch of a button. They are just as inexpensive too. RMPP for multiple links and prices.

I would far rather have this than mirrors etc

James Ball · February 8th, 2004, 01:33 PM

it will invert top to bottom at touch of a button right?

a lot of LCD flipout viewfinders do that. My GL1 comes stock with such a viewfinder.

What it won't do is flip L to R. Am I right or does the LCD you found do this as well?

Taylor Moore · February 8th, 2004, 01:36 PM

James this is what it say,

color/ brightness/ contrast/ volume/ mute
-video input 1 or 2
-Left-Right Picture Switch
-Up-Down Picture Switch
-16:9 or 4:3 Screen Ratio

I have not see this monitor.

Brett Erskine · February 8th, 2004, 02:06 PM

Hey Taylor since we are on the same page are you also looking for LCD's that have the addition horizontal vertical squeeze and stretch feature? In case your wondering why I would want that ...think of 2.35 anamorphics. Despite my efforts I havent found one. Would you like to help in the search?

Taylor Moore · February 8th, 2004, 02:49 PM

Sure would Brett, but I think chances are slim...I might need to check panavision/arri options? So you are looking for a LCD that will have the ability to stretch and squeeze to 2.35 with R to L and T to B flip?
Let me know how your achromatics work out...cause I'm DVX ready....if we can get this to work, I would be very, very pleased.

Brett Erskine · February 8th, 2004, 03:17 PM

Taylor- Thats right. I know Transvideo makes a box that you hookup to your video between the camera and the LCD but its more than $1000. Anything made for the exact purpose of unsqueezing to precisely 2.35 is most likely going to be expensive. Instead we should be looking for a LCD that has the general ability to progessively stretch and squeeze a image and we will just eyeball it unitil it looks right. Doesnt have to be absolutely perfect. Its just for the camera operator to view the picture correctly while operating because at the same time the camera will be recording the full CCD anamorphically squeezed version of the image on tape. Get it? Lets find it.

Jim Lafferty · February 8th, 2004, 08:01 PM

Check out these small (2.5-4") LCD screen kits with up/down, left/right flip modes.

No idea on pricings, though I have form-mailed them. Will keep you all posted.
