Finally, my 3 essays are completed for Uni and I've managed to tidy up my massive stack of books from the side of my desk
My eMac is now at the other side of the room
Let's congratulate Chuck on his year long achievement with his Completion Award, Perfect Attendance, and having the highest GPA in his class.
This is a pair of old TLRs... a Yashica LM my grandmother used to use and a Kodak Duaflex 2 I purchased for through the lens work.
People seem to have much passion for scarce things than things with large quantity. The reason behind is very obvious. Scarce things are more precious and valuable. Leica has introduced many high quality lenses of little productions, which have attracted a lot of collectors. Summilux-M 35mm f/1.4 aspherical produced during 1989-1994 is one of the excellent representatives. As the production processes were very hard and complex, it had only a limited production of 2000 items. In spite of the bigger size, its optical design and the sharpness of photos are much more excellent than early Summilux-M 35mm f/1.4. Thus, it has been chased after by many collectors.
Leica has always been having a strict requirement on the optical design of lens. Summilux-M 35mm f/1.4 aspherical consists of construction of 9 elements in 5 groups with unique feature of two front and back concave outer surfaces. The lens contains two hand-polished aspherical surfaces. They are of the same polishing method used in Noctilux 50mm f/1.2 in year 1966. Noctilux 50mm f/1.2 is the first lens in the world produced with aspherical surfaces to improve the aberration problem of non-aspherical surfaces. However, the hand polishing method is very time consuming and difficult. It cannot guarantee success. Leica experienced a lot of failures without giving up. After a long period of six years, these 2000 excellent pieces were finally issued. Leica’s spirit makes this scarce lens more valuable.
人們為何對數量多的東西沒有太大的熱情，卻爭先追趕數量稀少的東西呢？這不就是因為稀少的東西來得更珍貴，來得更有價值。徠卡 (Leica) 生產了很多高質素，而出產量又十分少的鏡頭，吸引了很多收藏家的目光。在1989-1994年期間生產的Summilux-M 35mm f/1.4 aspherical (雙非)是其中的表表者。由於製作工序繁複，只限量生產了2000支便停產了。除外型較大外，無論是光學設計，還是相片的銳利度，都比前期的Summilux-M 35mm f/1.4出色，得到很多收藏家的青睞。
Leica一向對光學設計很講究，Summilux-M 35mm f/1.4 aspherical (雙非) 使用9片5組的鏡片，擁有前後兩個凹陷的表面鏡片，在當時是獨有的特徵。這支鏡頭包含兩片人工手磨的非球面鏡片，它們的打磨技術與1966年Noctilux 50mm f/1.2的非球面鏡片的打磨技術相似，Noctilux 50mm f/1.2是全世界首支使用非球面鏡片技術製造的鏡頭，改善了球面鏡片的像差問題。可是人工手磨非常耗時，製作難度高，不能百份百確保手磨的成品理想，經過多番失敗後，以長達6年的時間才成功完成這2000支優秀的鏡頭。Leica不斷嘗試，永不言敗的精神，更加增添了這支產量稀少的鏡頭的收藏價值。
I come from Taiwan therefore I am a Taiwanese. Have you heard of Taiwan ? Taiwan is a great and beautiful country and it pronoun as T-A-I-W-A-N in English. Taiwan is located in Asia , on the East of China, South of Japan and North of Philippines. Taipei is the capital of Taiwan as it is pronoun as T-A-I-P-E-I in English.
TAIWAN ≠ China
Originally, I wanted to do a macro series of every Intel Pentium Processor chip that has been created, or perhaps more of a chronology of computer processing chips, but I was unable to obtain them in time for a class project I was doing this for. So, these are various parts to electronic devices such as remote controls, alarm clocks, computer keyboards, etc. I used a 60mm macro w/ an extension tube and primarily lit them from behind with a flash gun and filled in the front with on-cam flash.

السلام عليكم
شحالكم عسآآآكم بخير
بغيب عنكم كم يوم ماراح اطوول
بتوحشووني ="(
وادعـت خــلٍ لـي أـبيه و يـبـيـني
وأخفيت دمعي عن عيونه وشوقي
ضاع الوفا مع ما ضيات السنيني
لا عاد لـه شـمـس ولا به شـروقـي
قال توادعيني؟! وقـلت ارحمني
قـلبي علـى فـرقـاك ماهو شـفـوقي
I just got the 20.1 /Mega Pixel camera and I am looking forward to seeing how my Comic Con pictures come out this year. =)
