<p>Hi All,<br>

Valvula Films, post-production house in Chile, did produce last year a comparison demo test, between 35mm (motion picture) and digital cameras.<br>

Glass was Carl Zeiss MKII for all cameras.<br>

Stocks used were Kodak Vision3 500T and Vision3 250D, developed (as ECN-2 normal) at top notch Laboratory FotoKem in Los Angeles, California. The exposed and undeveloped rolls were sent by courier; and so got developed several days after the shoot; in an intent to also analyse real life shooting conditions in remote places. <br>

The stocks were scanned at Cinelicious, a great post-production company, also in Los Angeles area, through a DFT Scanity scanner, a scanner that can handle up to Density 3 (or a even a bit more), so compatible with Vision3 stocks. (their Dmax is much higher than other color negative stock, thus explaining the extended exposure latitude in the highlights). Output of the scanner was TIFF RGB 16 bits log/flat image sequences.<br>

Digital Cameras were Arri Alexa (in ProRes compressed format) and Red Epic X (R3D RAW compressed format).<br>

This is not a scientific test, of course, but helps to see some important differences, like highlights handling, flesh tones, and image texture.</p>

<p>Thanks for the comments.<br>

Jeff Livacich : thanks for the recommendation, I will also post on the APUG.<br>

John Shriver : The last time I did prepare Agfa AP-70 baths (compatible with C-41 films), I did process two times with those chemicals. The first time, was for this fireworks photos (one roll). Then one day later I processed another roll (a normal C41 stock, not MP stock). I also had the concern of what would happen (as you mention : will it get rem-jet all over the next roll?) , but the second stock ended clean with no apparent remjet debris. </p>

<p>AP70 has three baths :<br>

Color Developer<br>

Bleach/Fix<br>

Final Bath<br>

I noticed when developing the roll of the fireworks, that the Final Bath (that I beleive is a color stabilizer), was much darker, after using it on the processing. So I guess it is at that stage where the remjet was removed.</p>

<p>As a side note : On previous testing of this same stock but with C-41 development, the remjet backing layer was almost not removed during the processing, so I had to remove it manually (wet cotton with water + borax).</p>

<p>I agree with you that there is a risk of damaging the next rolls with the remjet debris, when using the same chemicals. That's why it would be better to process as much film as possible each time, and not reuse the chemicals - unless using AP70 ? I still have one kit of AP70 and will continue testing with it and C-41 on the next weeks. I will post daylight images too.<br>

By the way the images of the fireworks were scanned on a Nikon Coolscan 9000ED and the color grading was done via Adobe Photoshop.</p>

 

<p>Hi,<br>

Below are a few links of photos that I have shot in Valparaiso two weeks ago, using Kodak Vision3 200T 65mm motion picture color negative stock - that I did reformat prior to the shoot to 60mm wide in order to fit the stock into a 120 medium format roll. <br>

I did develop the stock through Agfa AP-70 (compatible with C-41). <br>

Color Developer was set at 38 degrees Celcius.<br>

The rem-jet backing layer was almost all gone during the process (specifically with the final bath), and once the film was dry, I did use a wet cotton (water + borax) to finish the removal of the rem-jet anti-halo backing layer.<br>

The stock was provided by Kodak Australia and Kodak Santa Monica, in late 2010, for an independent research about the potential to use MP stocks in medium format photography (using C-41 instead of ECN-2 process). <br>

Thank you to Kodak and in particular to Mrs. Ingrid Goodyear (Kodak Regional Business General Manager, Entertainment Imaging - Asia Pacific Region) for the help and support in getting that great color negative stock. <br>

I think this stock Vision3 200T, as well as other MP stocks as Vision3 50D, 250D, and 500T are great emultions for photographers.<br>

<p>I have been using the Vision2 50D (5201) with a Contax 139 Quartz and Zeiss lenses in 135 format; as well as the Vision3 200T for 65mm, reformatted (experimental) to 120 format, with a Rollei 6008i and Zeiss Planar 80mm lens.<br>

I consider their exposure latitude is very wide.<br>

I have been developing them through ECN-2 or C-41 (manual process, with a final manual removing of the remjet layer, using water + borax).<br>

I will post some images in the next weeks.<br>

5201 is an incredible stock (50D), if Kodak was able to improve it, then.... that should really be phenomenal, as was reported from Camerimage, on the CML board.<br>

Film is alive! (this stock is even available from an intermediate company in L.A in super-8 cartridges...).</p>

<p>Vision2 100T (5212) is also impressive. They have very wide exposure latitude. It would be great to see a tungsten negative film stock on 120 and 135, that could inspirate on those high quality MP emultions</p>

<p>Hello,<br>

slightly off topic, but regarding to Kodak Vision emultions, for motion picture, there are some remarkables emultions such as the Vision2 50D (5201 code for 35mm) as well as the Vision2 250D (5205) and Vision3 500T......<br>

A Vision3 250D (5207) might appear on the market soon.</p>

 

<p>Hello Evan,<br>

Thank you for your tip and servicing company info.<br>

When I turn off the camera, and change the lens, and then turn on the camera, the camera recognizes the lens and indicates the exposure metering info for a short time.... then that information is not longer visible, when I try to take a photo with that lens, I hear little "tic" sound, and generally the camera takes the photo after a while, but I can not control when.... That's annoying and strange as it only occurs with this lens.<br>

Anyway the Contax 645 is the best camera system I have used so far. <br>

Thanks again for your message.</p>

<p> </p>

<p>Hello,<br>

I have been working for a while, with a 645 Contax kit and a few lenses. Suddenly the 35mm Distagon, presented a problem, whilst the other lenses still works ok. When I fit the 35mm lenses, and want to take a photography, I hear a little "click" each time I intend to take a photo, but the camera do not take the photo. I also don't see the light metering with this lens..... After pushing several times the shutter button , the camera takes a photo, but no always. Please let me know what could be the problem, and if this is repairable in the field. Could this be a contact problem ?<br>

Thank you very much in advance,<br>

Best Regards<br>
