Apo 90/F4 Afi7白平衡Daylight 色彩prophotoRGB

[Lulumi 编辑于 2008-04-14 21:06]

谢藏色岗日兄！Daylight在LC11上看，色温6000K，色调63，有点偏红。在拍摄中，有点阳光时，试着把色调跳到50左右，色温调到5600K，反而显得不大自然了，好像Leaf的设计就是有点红红的。
明天“一眼通”就到了，先把几个显示器调调再说。

Billon兄你好,请教谈不上,
拍摄数据:白平衡设置AFi7 Daylight, 色彩空间prophoto RGB,后期微调反差.

请教：白平衡设置、色彩空间、后期处理程序。谢谢！

杨兄，140-280施奈德是老头还是新数码头？我以前有过一支施奈德哈苏口的CF140-280，在胶片上紫边也是相当的严重，不能忍受，修了，听说禄莱口的要好些，看来也有问题啊！提示一下：靠近长焦端别用11以下的光圈...

这事得找"好大侠".这只头用在数码后备上可能有问题,紫边...
局部100%

杨兄：变焦头爽啊，这个禄莱卡口的镜头要是能转接到康泰时上就好了！赞一个

有空请教OXYGEN的应用，行不？

谢！

OXYGEN是由LEAF的母公司CERO生产的用于编辑ICC色彩曲线、数据插值运算的密码型软件。简单的说就是你如果觉得LEAF给你的ICC色彩文件不够，你就用这个软件编辑个你想要的ICC色彩曲线来用。

更有意思的是以下两个人的对话（上边的回答下边的）：
大概意思是 月产量两百台很难维持fh公司的生存  fh的员工甚至曾经在公司困难时期同意调低工资 就是因为它们对自己产品的感情 fh的前都花在了研发上 并不像哈苏做了那么多的市场 因此hy6的价格实际是实打实的 并没有让客户付广告费用
相比之下contax月产2000 未能数码化而导致死亡 在epd看来如果是fh拥有contax 就不会发生这种事

我自己用6008II两年 除了80/2.8还有一个40/3.5 我觉得整个6008系统的完美和数量之少可以证明epd的观点 rollei的相机已经成为艺术 成为生命 而不只是商品和工具

James, you finally start to see the miracle that F&H production is. At 200 a month the Hy6 would be more successfull than the Rolleiflex 6000 series (!), which is still sort of legendary. F&H is a very lean company where people work because of the love for the products. (F&H workers even agreed to temporarily lowering their wages when they had to make the survival jump for Hy6 development, two years ago. Until the Jenoptik funding arrived.) F&H does not make any profit on DB sales as they don't sell digital backs. They earn their money making and selling cameras and lenses. And actually when you look at the figures of the investment in the Hy6 development it is even a bigger miracle how they conceived an entire camera system with such little funding. The big CNC-controlled machine you see on one of the pictures was purchased with the money from Jenoptik. Without that machine series production of the Hy6 would be impossible.

The trade-off of this sheer love for camera-making? There's no money left to pay more than one guy in the marketing department. You read that correct: one guy. Fortunately Leaf and Sinar have more people at their respective marketing departments. But still: for the exclusivity and amazing technological modernity of this camera system you pay only the very lowest price imaginable. You don't pay for fancy marketing. (Of course when you buy a DB it's a little bit different.) Had F&H been making Contax cameras I'm pretty sure that that brand would still be alive and kicking too, just like Rolleiflex.

QUOTE(James R Russell @ Mar 15 2008, 02:59 AM)
EpD,

What I find curious is the volume.  Will 200 sales a month sustain this system

I don't know the definition of a successful medium format camera platform, though I read that the Contax 645 was produced at the rate of 2000 per month.

If that number is correct and the fact the Contax was on the market from 1999 to 2005, even on the very conservative side that would put 72,000 Contax' in the market and even at that amount of market penetration the camera line was closed down.

At 200 per month, 2,400 per year how long will it take the Hy6 to have an impact on the market.

I guess I'm not understanding something about the numbers, because I have heard forever that the Contax was closed because they didn't have a digital solution, and even though it seems devleopment costs of the HY6 was split up among various companies, how does F+H make money at 200 bodies a month.  

Does F+H make money on Sinar or Leaf backs.

(This is not an attempt to flame the camera, I'm just curious about the logic).

另一些有意思的消息，其中之一：hy6月产量在150-200之间

- Hy6 production is now speeding up and real series production is a fact. The backlog in delivery to Sinar and Leaf will be pushed back and this also gives room for volume delivery under the Rolleiflex brandname. Soon series production of the Hy6 will be 150 pieces a month and will be increased to 200+ in the near future.

- According to F&H, demand for the Hy6 is high and therefore they will employ a total of 20 new employees so they can keep running the current two production shifts.

- According to F&H Hy6 specifications are met so tightly that back exchange between manufacturers will be no problem, without the need of in between re-adjustment. This in contrast with the new Hasselblad digital offerings that need back-body calibration.

- The 6x6 (multi-format) film back is still in prototype phase.

- Hy6 is a further development of the 6008 concept and for a vital part financed by Jenoptik. Originally Hy6 was thought as a fully open platform, but was limited in openness as a result of the deal between Jenoptik and Leaf and the taking over of Sinar by Jenoptik.

- Hy6 is for the largest part made in Germany, while electronics are designed in Switserland.

关于35m afd:
Please note that this is not a Carl Zeiss lens, but a Zeiss Jena lens. And in fact it is not a true Zeiss Jena lens either (meaning coming from Jenoptik in Jena) but it is being made by F&H in Brunswick, marketed under the Jenoptik owned brand name Flektogon. It is not expected that Carl Zeiss lenses in AF version will be introduced for the Hy6.

sinar的说法：66后背有可能会是变幅的66-645 同时接受120和220胶卷

- The 645 film magazine is the same as the one for the Rolleiflex 6008 (and as such available): it needs an adapter to fit it on the Hy6: this adapter is in production and should be available still in March . This 645 magazine accepts 120 and 220 rollfilms.

- The 6x6 magazine is new and in production currently (no release date given yet): the latest information I have is that it will allow to choose between 4.5x6 and 6x6 formats. It will accepts as well both 120 and 220 rollfilms.

I hope this answers.
Best regards,
Thierry

Leaf不会有那东西的。AFi的后背与Sinar Hy6的不一样。Hy6是通过转接环使用现有的后背，所以可以搞出一个旋转的接环。但Afi的后背是一体式的，无法用。

谢指点！这连天阴天，下午准备出去试试灰卡，按照说明书要求的角度，分别留下几个点的数据。在电脑上调整，用Prophoto RGB，不动灰平衡，红色消退了些，显得正常了。用Prophoto RGB色彩管理，在Win的Acdesee（没有色彩管理）中看，特别灰，转为sRGB，立刻就正常了，可能PC机的屏幕不能完全表现Prophoto RGB吧。
请教：oXYgen是什么软件，网上搜索不到。

leaf年内会发表可旋转式后背接口 {sinar hy6已经有了这个东西}
原文：

..... besides all the great AFi software and firmware upgrades, it is my belief that the first AFi back (hardware) upgrade will be the integrated rotating (revolving) mount. This feature would make the AFi unstoppable in the MFDB world. One thing not talked about is Leaf's machined hardware interfaces that have always been world class, and that begins with excellence in design. So do not to disturb Leaf's mechanical hardware engineers. Just reap the benefits of their hard work.

给每个光源放一个色卡，操作起来不现实啊。

按计划，35mm应该不迟于今年7月发布。但又有一说，施奈德计划走一步看一步,如果50mm AFD卖得不好，35mm就要推迟了。

对于AFi6或者7来说，不上60lp/mm的数码头，发挥不出后背的潜能

Schneider AFD Tele-Xenar 150mm f/4 AFD HFT PQs

The all-new AFD autofocus lenses by Schneider-Kreuznach are the result of cutting-edge design, innovative technology and permanent optimization. High-speed communication between camera and lens is friction-less and free from wear due to the 10-contact gold-plated strip. All lenses are fully synchronized over their entire shutter-speed range and excel by optimum sharpness, color balance, brilliance and speed.

AFD lenses are based on the same formula as the well-established AF lenses, but are manufactured and inspected with considerably stricter tolerances so that noticeably higher resolution and contrast can be achieved in series production. AFD lenses are tested to a resolution standard of 60 lp/mm (as compared to 40 lp/mm for AF lenses). This is essential for the more stringent requirements of high resolution digital photography. PQ series lenses have a maximum shutter & flash sync speed of 1/500 second while PQS series lenses have a maximum shutter & flash sync speed of 1/1000 second.

Furthermore, the differences in mechanical design are clearly visible: AFD lenses eliminate the manual aperture ring of AF design. Menu-driven aperture control in the Leaf AFi works faster and more comfortably than in other cameras and eliminates the possibility of operating errors. All Manual focus, AF and AFD lenses are fully compatible with the AFi.

Additional Features:
Specially designed for digital photography - The AFD lenses by Schneider are the result of cutting-edge design and specifically created for use with high resolution digital camera backs, the the unique Direct Drive technology developed by Rollei, with its microcomputer-controlled, motor-driven diaphragm and shutter for precise, accurate performance. Lenses are fast, sharp, deliver brilliance and color balance and are fully synchronized at all shutter speeds. The result is images of uncompromised quality.

Leaf shutter - The leaf shutter blades in the PQS lenses are hand-stamped in Germany of specially made carbon fiber produced for the aerospace industry. They are extremely thin and the smooth frictionless blades work on an air cushion. The shutter and diaphragm in the lens are driven by two linear motors and controlled with maximum precision in 1/3 increments by the camera’s microcomputer.

Glass - AFi lenses include advanced glass types with particularly high refractive indices. These provide a combination of proper lens curvatures and suitable glass types, optimally corrected for sharp and brilliant images.

Anti-reflection coating - All lenses include High Fidelity Transfer (HFT) coating for optimum flare suppression and brilliant colors. The coating consists of special ultra-thin films evaporated on the lens surfaces. The result is a noticeable reduction in the amount of light reflected from the lens elements and thus less contrast-degrading flare. In addition, light transmission is increased, allowing full use of lens speed.

呵呵，billen兄客气了，要追求色彩的准确在单光源条件下用灰卡的效果肯定是最好的，多个光源呢，就多设几个灰卡，把色温和色调的数值平均一下，效果也不错，以前也经常选用软件设置的各种色彩效果，后来觉得真的没必要了，就用PROPHOTORGB吧，后期交给oXYgen和PS去做；关于mos文件的无损压缩，官方的解释是没有影响，但是其代价是不能用PS解压原始文件，我现在有时候在LC11中冲完图继续保存成mos格式，然后再到PS里做特殊的解压，所以全都选择无压缩mos，您也可以试试。大家相互学习交流,也欢迎你来新疆做客

深得教诲！
请教：PS色彩空间里有Prophoto RGB选项，是否改为Prophoto RGB色彩空间。以前的1Ds 2、R-d1等也保留着RAW格式，也想试试。
另请教：AFi有无压缩mos格式，可以压缩30％的，是否用过，冲图有无障碍？
