トランスメディア提供アイコン01 Multiple Exposure(多重曝光)

奧運期間的藍天很漂亮,雖然不能到郊外拍美美的風景照,但也不可以錯過機會。於是,過去幾星期,在家裡做了一些多重曝光的攝影實驗。

相機用Nikon FM2, 底片是富士幻燈片RDP III。鏡頭主要是AF 50/1.8,有時候會用ais 125/2.5。我最近愈來愈喜歡用彩色幻燈片了。主要是幻燈片出來的底片無論色彩和層次比較美,拍攝的成果可以忠實地從底片上直接看到,欣賞幻燈片是一種「處身現場一樣的」享受,本來最喜歡幻燈片。加上現在掃瞄技術進步了,只要花20元就可以找晒相店掃瞄整卷底片,放上網上跟人分享也可,在家打印也可。跟別人分享忽然變得非常經濟實惠。以前要與別人分享用幻燈片拍攝的成果,晒一張相就要幾十塊,幻燈機也非常不方便。時代不同了。希望一直有好的幻燈片用。

(一) 第一幅是用多重曝光企圖製造High Dynamic Range的效果。


由黃昏7:15至晚上9:00共分3次曝光。天空有一點點過曝,但建築不是只有影子了。但從建築物的燈光看來,第三次在9時的曝光的時間是太短了。

(二) 這一張,曝光了2次。


(三) 第三張也是2次。這張在第二次曝光用了手電筒打背景,拍街外的樓宇的燈光。


(四) 這一張仍然是2次。一次在早上,一次在日落。


(五) 一樣是2次。


(六) 這張分了3次曝光。


(七) 這一張是2次。天空的方向是上下反轉了。


(八) 這一張是兩次。第二次時故意把主體以外所有內容過曝,成了白色的背景。

トランスメディア提供アイコン01 What photography really is...

I received a e-mail from my dear friend after I posted a post with several Black and White photos on July 27. We discussed about wet technique on Black and White film-processing.

At the end of his last email, he comes up a feeling that digital camera make all the hard way of his day easy to the young generation of these days. I am by half-and-half agree with his opinion.

Today a young folk tries to make his point on the wonderful focusing speed of USM function of Canon EF70-200/2.8 winning the heart of Journalist as the Journalist need that speed. He labeled me as "Human God" as I told him even manual focus can be fast enough to meet the Journalist demand and proved it with my confidence and successful experience on sports photopraphy. He argues that not many journalists now can do manual focus as I do.

Oh my God. Let's remember that there was no AF camera in the old time and journalists still need to take sport photos. Moreover, even there were AF SLR and USM lenses, but a lot of skilled photographers still prefer manual focus because the AF system had not yet mature and so not accurate during the film age. There were a few top professional able to capture jaguars in the past. What's the big deal to have a serious amateur to MF sports? I would say that journalists nowadays can't do MF well because they are just dependent on AF and never bother to practice MF skills. But are they world-class professionals whose boss can rely on to any challenging task? I wonder. A professional fails the task just because of accidentally-broken AF system, how reliable is he?

Although digital camera make photography sound easier, there are some aspects of this new era may worth thinking about.

How many pages is there in the official Nikon FM2 manual? very-simple-plus-a-lot-of-large-picture 49 pages. FM2 has been almost the top of the line of its age. how many pages for Nikon amateur's D70? Amen. I have never tried to read it. Of course not to D80, either. I also don't have much memory on reading manual of my first digital - Olympic 370UZ.

When I first time have my camera to take photos, I was a blank page to camera. By that time, camera was something only my dad and mom could touch. But I took a few minutes to read several pages of FM2 manual, I had already knew how to operate the camera and knew the basic concept of using different shutter speeds and apertures. The next thing to do was doing experiments with combinations of shutter speeds and apertures. A lot of time was spent on observing light and targets.

What's about newcomers on digital days? After a few days, I still hear new buyer of DSLR fighting on understanding all buttons, tens of options on menu, ISO, and so and so. A lot of technique and art theories we used to build it up gradually when we buy and use different films and gears. They now all "menuized" (menu + ize) and become a ocean of options on DSLR. Taking photos becomes fighting with menu. Even an experienced amateur like me still feel busy to take photos. Is that photography? Where is my effort put to?

After using FM2, FTN, F-100, D70, D80 and other Portable Digital Cameras, I found that it was F-100 make photo-taking the most relaxing among the above-mentioned cameras, but I still always border by the weight of SLR system.

What is photography? Observing light and target, then capture it?

I start loving my Contax G2 very much, and also start understanding why there are so many people like LOMO and Holga. Holga is a cheap 120 camera. Someday I may get one.

トランスメディア提供アイコン01 135全片幅DSLR的思迷~淺談焦段的特性

有很多人認為,現在有很多超廣角鏡推出,即使數碼單反要把傳統135相機的焦矩乘大1.5倍來使用也不會不方便。不明白全片幅數碼相機的價值在哪裡。

トランスメディア提供アイコン01 HIGH DYNAMIC RANGE PHOTOGRAPHY

最近聽聞有一種叫HIGH DYNAMIC RANGE PHOTOGRAPHY的電腦技術,可以製作低反差的相片,所以就試一下。

我拍了一組數碼相片(EV=-2, 0, 2, 4).見下圖。

再用硬件合成一張HIGH DYNAMIC RANGE IMAGE。(見下圖)
a0003697_21332291.jpg


好像不錯。

不過,這樣用電腦製圖並不是捕捉光的攝影,以及如非需要,我還是不會常用。

THIS IS NOT ART OF PHOTOGRAPHY.

トランスメディア提供アイコン01 Second-Hand CONTAX G2

Since my health is bad, my hand shack even when the shutter is fast. I can't hold any SLR around to take photos now. Therefore, I bought a system of Contax G2 with 3 Zeiss Carl lenses. Now, start selling the SLR stuffs.

First photo with G2:

トランスメディア提供アイコン01 Scanning and Printing

The following messages are replies from "besati" to respond to my technical problems related to scanning and printing.

windywood:
English>Is a file created by Nikon D70 large enough to make a 12R print?
Chinese>各位對D70 放 12R 相有甚麼評價?

besati:
The resolution of the image on your monitor is 72 lpi (lines per inch) x 72 lpi. For normal printing, 300 lpi x 300 lpi will give excellent results. However, for common daily use, 200 lpi x 200 lpi is still OK if you are not critical.

For 8R prints (8" x 6"), using 1500x1200 jpg is equivalent to 187.5 lpi x 200 lpi which should be marginally acceptable. Therefore, for 12R prints (8" x 12"), using a 1600x2400 (3M pixels) source will give satisfactory results to common people.

However, if you wish to progress in serious photography, working in RAW and TIF format is a MUST.

windywood:
English>When I scanned old photos with 1200dpi, the lines and edges in image was not smooth at all and look like saws. What is the max. dpi value I should use for scanning photos?

Chinese>我想問問,如果我用一張舊相去scan做檔案,我最大可以set個scanner的dpi值做幾大呢? 上次scan相,我set做1200dpi,看原圖出晒狗牙了。


besati:
English>The output picture quality for a scanner is determined by optical resolution, not the software resolution, so the resolution power of the lens in scanner is very important. That's why an Agfa 600dpi Scanner can deliver better scans than a HP or a Taiwanese scanner.

Before scanning, the size of print should be known, then is multiplied by 300lpi, finally the result is divided by the area/size of scanned object. The final result will be the dpi value to set on the scanner.

Chinese>Scanner 最重要是 optical resolution (光學解像度) 而不是 Software Resolution (軟件解像度),所以 Scanner 的鏡頭質素十分重要。如 Agfa 600dpi Scanner scan 相可以靚過 HP 或台灣牌子 1200dpi Scanner 絕不出奇。

Scan 相前要先決定打印的尺寸,再乘以300 lpi 得到scan圖的總解像度,然後除以原來相片的大小,便可得到 scanning 所需的解像度了。

舉例 scan 36mm x 24mm (1.5" x 1") 的菲林,打印 A3 (16" x 11") 紙。
總解像度 = 16x300 及 11x300 = 3300 x 4800 pixels
Scanning 解像度 = 4800/1.5 及 3300/1 = 3200 及 3300 dpi
所以在電腦 Twain Software 上選 3600 dpi。
