Inside to the Colosseum. September 13, 2013. Shutter Speed: 1/4000. F-stop: 5.6. I really like the composition and lighting of this picture. I like all the lines and patterns that this picture is composed of.

Savanna.  Shutter Speed: 1/3200 and F-stop: 5.6. This picture is under exposed but i really liked the pose she did and how you can follow the angles and lines of her body with the angles of everything around her.

FRANCE. Clamart. Library for children. Built by the "Atelier de Montrouge": Jean Renaudie, Pierre Riboulet, Gerard Thurnauer and Jean-Louis Veret. Ile de France. Haut de Seine. 1965.

I really like the motion of this picture how you can see the spiral to the ceiling with all the kids faces peering over the side of the stairs. I also love how it was done in black and white because it gave off a different mood rather than if it was done in color. The childrens facial expressions are also interesting because they are all different and they are more serious. So it gets you thinking about what they are thinking about and what they are trying to do.

RAW vs JPEG

JPEG – JPEG files are processed right within the camera. How exactly they are processed varies from model to model. While color temperature and exposure are set based on your camera settings when the image is shot, the camera will also process the image to add blacks, contrast, brightness, noise reduction, sharpening (which you can see in the example above) and then render the file to a compressed JPEG. These files are finished and can be viewed and printed immediately after shot.

RAW – RAW files are uncompressed and unprocessed snapshots of all of the detail available to the camera sensor. Because RAW files are unprocessed, they come out looking flat and dark. RAW images need to be viewed and processed using your camera’s software or in more robust commonly used software like Adobe Photoshop, Lightroom, Aperture, etc prior to being ready for display or print.

CCD vs CMOS

CMOS and CCD image sensors convert images (light) into electronic signals. CCD sensors are slightly cheaper and are the older, more mature technology. CCD and CMOS sensors are susceptible to different problems — CCD sensors are more susceptible to vertical smear from bright light sources, while CMOS sensors are susceptible to skewing, wobbling and partial exposure. However, neither technology is a clear winner over the other in over all image quality.

CCDs use a global shutter, which exposes the entire image simultaneously. This can lead to blur if any motion occurs in the image during exposure, but a high shutter speed prevents this problem.

CMOS sensors are equipped with “rolling shutters,” which expose different parts of the frame at different points in time. This can lead to skew, wobble and partial exposure in photographs.
