大名公司需要一套小名公司生产的成套设备用来生产石英表，双方找未名公司商议，由未名公司购买并直接租给大名公司。于是大名公司、小名公司、未名公司签订如下合同：(1)由未名公司付给小名公司货款700万元，于当年年底和第二年年底两次付清，货款付清后所有权转移；(2)小名公司将精密成套设备代办托运给大名公司；(3)大名公司承租该设备，期限为 10年，每年租金100万元，于每年12月底向小名公司支付；租赁期间届满后，该设备归大名公司所有；(4)因标的物未及时交付或存在质量问题，由大名公司向小名公司行使索赔权利。合同签订后，小名公司如约将设备代办托运给大名公司，大名公司调配安装后投入使用。其间，由于未名公司迟延付款，小名公司一度以收回设备相威胁，严重影响了大名公司的生产，给大名公司造成较大损失。6年后，由于国内钟表业竞争激烈，大名公司将该设备租给不名公司，不名公司在使用过程中因不可抗力导致该设备灭失。根据以上案例。回答以下问题：

Blind photography sounds strange．But a striking exhibition of photographs in California argues that it develops as a result of the contemporary art．The show "Sight Unseen", at the California Museum of Photography until Aug．29, includes everything: underwater scenes, landscapes, abstracts and everything else you might expect from a "sighted" photographer．

How do the blind take their photographs? Some rely on assistants to set up and then describe the shots （镜头） , and others just point and shoot in the right place．"Just like any good artists," says McCulloh．"They have their unique ways of operating．" One participating photographer is Pete Eckert, an artist with multiple degrees in design and sculpture who only turned to photography after losing his vision in the mid-1990s．He opens the shutter （快门） on his camera and then uses flashlights, lights, and candies to paint his scene on film．A former fashion photographer in Chicago, Weston, lost his vision due to AIDS in 1996 and focuses on images of destruction and disability．His photos are also a star of the show．

What do gallery-goers say? "I was very impressed by it．The technique and experience was amazingly different," says John Hesketh, a printmaker in Anaheim．"You never have a sense of feeling sorry for these people because they've worked very hard to prove their value．"

Beyond the praise, however, the exhibition also makes a great example for disabled people everywhere．That point was explained in early May during a discussion on the TV show．At the very end of the talk, one attendee expressed his opinion．"This exhibition is extraordinary and revolutionary for many reasons．I think that by being an artist with a disability, you are continuing the work of those people who fought for basic civil rights to gain access and to have a voice．In that way, it's so wonderful that your photographs say it all．"
