Aperture
  Except from ISO and shutter speed, aperture is also very important when you take your images, the aperture stop of a photographic lens can beadjusted to control the amount of light reaching the film and image sensor. The lens aperture is usually specified as an f-number, so you can see the different choice on the camera, like f/2, f/2.8, f/4, f/5.6, f/8 and so on.
  In the concept of apeture, there is an important aspect that called maximum and minimum aperture, for example, f/1.4 to f/22, in this case, f/1.4 is the maximum aperture (the widest opening), and f/22 is the minimum aperture (the smallest opening), this value is also known as lens "speed", as it affects the exposure time, and the exposure time of the f/2 is one quater that of f/4.
  In combination of sutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light, typically, a faster shutter will require a larger apeture to ensure the sufficient light exposure, and a slow shutter will require a smaller aperture to avoid excessive exposure.

  This blog will talk about my trip to Stanmer Park, I went to the park and took some images in the countryside, these photos were abot the old church in the village and some flowers that I thought interesting and beautiful.   The two pohotos of the old church is the best ones in all the images about the place, I was standing under the architecture and using my camera to make a low-angle shot on the church, the shutter speed in the first image that I used was 1/160s, and the aperture was f/9, the image contains the top of the church and the tree just above the building, the second image I used 1/200s sutter speed and the aperture was f/10, the two images I all used the building and the tree near it, it was the combination of architecture and nature.   From the photos that I took on the flowers in the countryside, I think these two are the best, the first image I used 1/200 shutter speed and the aperture was f/5.6, the purple color of the flower was beautiful and cute I t

  This blog will introduce a famous architectural photographer, his name is Andrew Prokos, he is an award-winning architectural and fine art photographer based in New York City. His photos have been widely published and exhibited in museums, galleries, and art collections in the USA, Europe, and Asia. Andrew’s high-definition fine art photos range from 120 inch wide large-scale cityscapes  to more intimately sized matted and framed photographs.    Andrew captures his ultra-high-resolution fine art images using large-format film and digital capture. This allows us to produce astonishingly detailed large-scale prints up to 150 inches wide. Andrew’s photos exhibit high-definition and the unparalleled sharpness and clarity found in prints sold in museums and art galleries. Interior designers, architects, hotels, and corporate art collections have purchased and proudly display Andrew’s photographs in their most important spaces.   Andrew has taken many images on the architectures both

Architectural photography   My photo project is about architecture, so this blog I want to introduce something on the architectural photography.    Architectural photography   is the photographing of buildings and similar structures that are both aesthetically pleasing and accurate representations of their subjects. Architectural photographers are usually skilled in the use of specialized techniques and cameras, in my opinion, photographers use cameras to take images on the architectures they choose is to tell the audiences the story of the architecture.   For techniques on taking architectural photos, tr aditionally, view cameras have been used for architectural photography as they allow for the lens to be tilted or shifted relative to the film plane. This allows for control of perspective, as well as a variety of creative possibilities, and in a similar fashion to landscape photography, a deep depth of field is usually employed so that both the foreground and background (
