Learn about the process of basic imagine correction

The knowledge we learned this week is basically about Photoshop imagine correction. Using the shoes project, we learned several ways can make our picture better.

The first one is to set up the photo size for the shoes. We want the shoes, which is our main object to be placed in the center. Thus, we use the “crop” tool to adjust the photo. To adjust the tonality of the shoes picture, we used the “levels” tool. “level” is a tool to adjust the overall tonality. The second tool we have learned is “Brightness & Contrast” tool. This tool can adjust the brightness in more detail. Through this tool, the picture can be really vivid without being strange. “Hue/Saturation” is another tool for adjust the overall color. The more saturation the picture has, the color would be more accentuated. About the “Channel Mixer”, I personally like it because it can help use to adjust the magnitude of red, blue and green individually. If I can choose my favorite tool this week, “Healing Brush” will rank the first. I really like it can fix the little detail of our photo. Contrast with the other tools, this can be used to fix little part of our picture.

The layer adjustment is the other thing we learned about Photoshop this week. Putting our each correction of picture into separate layers is necessary. In this way, we do not need to worry to start over again if we made any tiny mistakes. That saves a lot of work. When we find out we do not need the correction any longer, we can just drag the layer to the trash icon. If we need to do something further base on the previous correction, we can just duplicate the layer and add more. We acquaintance how to view our correction is a proper way by putting them in certain order. The “Eye Icon” will be able to help use to determine which correction is needed.

All the tools and adjustment about Photoshop are useful. There are certainly more function of them which I do not mention of. I wish I could remember them in a better way.

The DSLR

  The DSLR simply means digital single lens reflection. A DSLR camera is made of the body and lens. The main body is the machine that captures the imagine. The lens is the machine we use to alert the imagine we want. Different lens can make the imagine diverse. The wide angle lens can accentuate the imagine angle. Using a zoom lens will make the photographer be able to zoom in the imagine before exposure. There are several buttons on the shooting model dial, M, A, Tv and P. "PASM" dial, they typically provide as minimum Program, Aperture-priority, Shutter-priority, and full Manual modes.  
The exposure generally refers a single shutter cycle. Usually the exposure will be automatic exposure is the total amount of light allowed to fall on the photographic medium (photographic film or imagine sensor) during the process of taking a photograph. There is a physics equation of exposure, H=Et. H stands luminous exposure. E stands image-plane illuminance. The t stands the time of exposure.
