Ettore: Do you have a photo of the slide-projector or achromat?

Ettore Giraldi April 22nd, 2006 04:21 AM

Hello guys
I'm writing a notebook text about all the things you said before my last post ( its takes a eternity :D)

Here's a larger new footage, dont look at the colors ( wrong setup colors 'in camera') 450 x 360 .Mov

I'm coming back

thanks

Ettore Giraldi April 22nd, 2006 04:56 AM

Thankiu guys for your attention!

Hi, David... No I'm sorry for the pics, but its very very easy, 'to level' I meant wash it well to take off the particles... and than apply the cream, not too much, evenly, after with a soft paper or cotton try to polish it, like you do on your home floor, on the car etc.

Jamie I saw your videos, much better... but I still thinking you need an achromat... did you provide? is it coming?

I would tend to think this is due to the lens you are using and not the adapter but when the DOF is very shallow it doesn't take much misalignment.

Good choice of song, by the way - Frou Frou is good stuff! :)

Thank you, yes youre right, my dof box the ugliest thing in the world! :D ...the GG is tilted, and vibration its like a earthquake, the slr lens maybe helps to that strange dof.... Frankestein!
Oh, my God, the music I thought was "Imogen Heap"! but I like frou-frou too ;)

Carl, first of all, congratulation for you website, i like its design and contents.

its a simple doublet achromat, with two cemented pieces, can shot photos now because its glued inside metal rings, maybe it will be there forever :) ... its like this one here:
Achromat Photo

thanks

Carl Jakobsson April 22nd, 2006 06:17 AM

Thanks! The site is in swedish but I guess it's quite fun to look at anyway...

One more question, you wrote "ancient slide projector". Is it like one of those;
http://images.tradera.com/951/31601951_1.jpg
http://images.tradera.com/723/22401723_1.jpg
http://images.tradera.com/273/31848273_1.jpg

They all look quite ancient IMO... :) There are a lot of second hand stores around and I'm thinking of buying one. It would be faster, easier and cheaper than buying an achromat online. Your adapter seems to work great and gives exactly the kind of picture I want. I'm so glad you're willing to share your recipe.

Also, what are the specs of the PCX? Did you buy it online?

Ettore Giraldi April 22nd, 2006 09:17 AM

Carl, here is a picture with some pieces of My Slide Projector model, as you can see its a jurassic type, yours is far better than this, if they do not cost a lot...
I think all these projectors have inside both lens, Achromat and Pcx, mine have two Pcx and two Achromat (one with two pieces cemented together and one Air-Spaced ) don't ask me why! :)

This site, in Germany, sells Optosigma products (Laser2000.de) I dont know the prices, I'm afraid they're expensive...maybe that old machines (they usually have very good lenses) from Tradera.com are more economic then one single good Achromat lens

David Delaney August 26th, 2006 08:23 AM

Your footage is some of the sharpest and cleanest I have ever seen! I would love to see the rig you are using?

Also, your Artsmell website does not seem to be working...

Juro Stehlik August 26th, 2006 08:43 AM

I agree with David. Perfect job Ettore! Is it possible, that you write some details about your adapter or post some photos?

How did you make your ground glass? With Sillicone Carbide? What number? Thanks a lot.

Frank Hool August 27th, 2006 02:35 AM

Ettore, outstanding! How big image plane You are using?

Ettore Giraldi September 1st, 2006 05:11 AM

Thank u all guys!

Yasser Kassana September 1st, 2006 06:38 AM

Ettore, that is the best footage from a DIY adapter I have ever seen. I mean in my eyes the G35 is the best around. Period. But your footage has just beaten it.

I think all you guys out there who are making adapters(sgpro, brevis etc, )takes some notes and tips so you can deliver us a picture quality of this magnitude!

Well done. I'd even buy one from you Ettore.

Toenis Liivamaegi September 1st, 2006 08:15 AM

Whoa, that`s sharp from edge to edge.
It`s a good thing when adaptor like this is not universal but dedicated to one camera model.

I wonder if there`s some sharpening applied in post?

Regs,
T

Juro Stehlik September 1st, 2006 03:30 PM

Ettore, am i understanding right from your images, that you are using +7 achromat and +10 macro simultaneously?

Rich Hibner October 1st, 2006 01:05 AM

2 questions. 1). Why no more Nivea? I thought it was a big part of your design. 2). You put "Sandblasted ?" Did you just put a 320 grit sand paper and sand it down yourself?

-Rh

David Delaney October 1st, 2006 09:28 AM

I agree on the footage, sharp with excellent colours. I wish I could find a projector like that here in North America because those must be great lenses? Mine look like that, but your shots don't have barrelling or fuzziness around the edges that mine do...


Anyone find projector like Ettore found? It must be a good one with the right lenses.

Ettore :
How are you holding the achromat in place? Also, what is the spacing like for the PCX - it is hard to tell from the photo...?

Frank, thank you, I don't know, just zoom on the gg image trying to avoid the vignetting.

Yasser, lol, thank you! but I don't want to sell these things, all I know
about these dof machines I learned here.
I use this $ 50 SLR lens and
$ 20 achromat from this italianEBAY SELLER
He does whatever you want, you can send him a email and ask what focal what dia you need etc.
"Objective diameter 51mm Focal 180mm, with optimal mc treatment..."

Sure! I said about the editing in my first message, but just a little, normal image enhancement.
gain, curves, gamma and sharpen. But I can assert to you that the Dv footages are pretty good,
clear almost as normal shoots, its not a heavy 'make up', the informations must be there in the
files, you couldn't do much in post if they're not.

Yes, my Canon XM2 can't focus well without a strong close-up optical assemblage, maybe i need a single acromat
with a stronger focal lenght.

1-as you can see on my new footages the cream doesn't changes the image quality, you can do the same with a 320 grit sandpaper.

2- no, sorry, my english is so... :), sandpaper and my only hands.
i don't know where you are from, i don't know if there is a grit standard for each country, here in Italy 320 is fine and you must work over the gg very well, patiently, when you think it's good, it's not! continue...wash it evenly and continue.

David, now i'm using that achromatic lens i bought on Ebay for about $ 20 (see links above), it's good, no chroma aberration, as i said up there the seller is a very kind person and he does whatever you want with good prices by email.


Please take a look, is the same adapter, smaller, made inside a pvc round box, here are the Pics
and this is a Video testing it

regards

Ben Winter November 3rd, 2006 02:03 PM

Ettore, from the pictures I see a wire going from your XM2 to the adapter...seems like from the flash/hotshoe to the adapter...what is that? power? Yet I see a battery pack...

Sam Jankis November 3rd, 2006 07:11 PM

Wow, that footage looked great!

Ettore Giraldi February 1st, 2007 04:21 PM

Ok, I know, for me it's just a joke....i like to shoot my sons growing up,
i think most of us here like to share results, no matter if happens with a comercial or a home made device, like mine.

I'll delet from my server all that videos linked above and put them togheter in THIS page,
in .flv format, more easy to update with a video playlist.
Take a look, there's some new little clips.

Thank you guys!

Rafael Lopes February 14th, 2007 07:46 AM

Ettore, your adapter is simply amazing. I agree with Yas, it is head to head with the best (IMHO the G35). I sent you an e-mail with some questions about it. I would really appreciate if you could get back to me.

Rafael Lopes February 17th, 2007 06:03 AM

I went to check out the original manufacturer's website (www.wdr35.com) and I downloaded all the videos, but none held a candle compared to what Ettore's alternated version showed us here. Ettore, YOU should be working with the manufactures! Your results (along with the G35's) are the best I've seen in many years. I think all the pro adapter manufacturers out there should take at look at Ettore's footage and get cracking.

Hurcan Emre February 18th, 2007 05:15 AM

just one question..
 
the metal part you used to hold the gg to the motor ??

what is it called? ( i see you have writen it in your language but i couldn't figure it out)

You have some great shots. Especially the one with the grapes i liked it most.

have a nice day
Hurcan

Ettore Giraldi February 18th, 2007 01:19 PM

Hurcan, its a Prop Adapter, used by hobbists, on little eletric airplanes.
some links:
http://www.hobby-lobby.com/propadap.htm
http://1301774.estore.networksolutio...tail.bok?no=82

Thank you guys, believe me, the Wdr35 adapter its a really good device,
and i must say you that the achromatic they're using is better than mine.
the GG treatment is the same, with the same grint paper.

Maybe my results comes with more accurate editing, gama, gain, curves, sharpen...
maybe when shooting with my XM2 i take care about good manually shots, my
opinion is that, little bit underexposed to achieve better colors saturations and
flexibility when you have to edit, is important not to burn highlight areas (imho)

The material is all linked up in the last posts, economic lenses, plastic disc, sandpaper number
1/4'' 3CCD camera, no secrets... :)

As you can see
there's no absolutly any chroma aberration and the footages are really lightly and that is a pretty good start!

Ok, i'll post some footage without any kind of editing.
:D

Ettore Giraldi February 19th, 2007 11:24 AM

Update!
The first footage named "Raw Clip", just increase the luminance (was too dark) and
flipped the frame... you can notice some vignetting, the color are original as well as the sharpeness.

Thanks

Rafael Lopes February 25th, 2007 12:26 PM

I keep going round and round and I always come back to the same. The original adapter's footage is not half as good as Ettore's and it costs as much as the M2 and the Brevis. If they followed your method it would be a best seller FOR SURE. You should really talk to them. I've spent years looking into 35mm adapters (and a lot of money) and I can't get over how good this footage looks. It's really a shame to deprive the world of such a magestic tool. Please Ettore, talk to them. Show them your work and tell them what you did to your adapter. All the 35mm adapter enthusiasts are counting on you to lead us from the blurry shadows into the razor blade sharpness.

Ivan Brasen February 25th, 2007 04:42 PM

Ettore, your footage looks really great !

Rafael Lopes February 27th, 2007 03:01 PM

Ettore, I mentioned your adapter at the dvxuser forum and a huge debate presented it self. I-m promoting the adapter big time. The guys who make it should send me one for free ;D

Ettore Giraldi March 1st, 2007 06:16 AM

Ahahaha, gracias Lopes!

By the way, the guy that told about "no blacks" on the footages, i think he's right, but this is about my Canon XM2 and the post treatment i gave to the clips,
The point is: the adapter produces sharpen images? what about color abberrations?
distortion? light loss? the 'bokeh simulation', how is it?

These are the questions people have to do themselves when analizing a 35mm-adapter, cameras o CC doesnt matter, i have and old 1/4 ccd camera, my SLR lens is
a Yashica ML ( 50 $), acromatic (15 $) but my images are too close to the normal footages (without adapter), there's a little, but little difference between them.

He was right, i can notice "no blacks" watching the clips on my portable notebook, so my other upstairs desktop has a bad monitor calibration (i'll try to fix this).

No, I do not use cream anymore on the gg.
Yes, this is a homemade device, not for sale, not professional, no budget, just to share personal technical experiences.

Thank you

Hi Ettore,

_if possible_ please send one short original (no color correction and any post production) DV video sample ...or deinterlaced snapshots

thanks,
Robert

Stephen Pipe March 4th, 2007 12:59 PM

That is truly awsome footage, it's amazing how good a DIY adapter can look.

James Mather March 5th, 2007 07:03 PM

Ettore - beautiful footage
 
So Ettore, Well done - your pictures are beautiful - certainly the most vivid and clean adapter footage I have ever seen - miles ahead of everyone else. May I ask a question - in the end - is the main thing the 320 grit and the washing or the CD - what do you consider the most important element?

Many thanks

James

Noah Yuan-Vogel March 5th, 2007 10:33 PM

Really nice looking footage, could you give me an idea of what sort of color correction was done or is that look largely due to the adapter itself? between the amazing sharpness (maybe that is hard to judge with 450x360 clips), lack of chromatic aberration, and great color correction thats some of the best looking 35mm adapter footage ive seen. the footage looks a lot like film, maybe its desaturation or low contrast. Any details about your techniques would be greatly appreciated.

James Mather March 6th, 2007 02:44 AM

Yeah, the COMPLETE lack of chromatic aberration and light dispersion along edges is really impressive (I would love to see a couple of HiRes grabs - all the links at the head of this thread are regrettably gone) - any chance that you'd dig up some stills or higher res footage Ettore? Thx. J. Also where would I get a glass GG system?
