When using a digital camera one has three options to save a photo, RAW, JPEG, or TIF.

1.     RAW: Claimed to be the best way to save a photo. For three reasons,

a.     Using RAW one can adjust the white balnce of a photo.

b.     Using RAW one has more freedom to adjust exposure and colors. JPEG you cannot change.

c.     Using RAW there is mire room to make general color adjustments.

2.     JPEG : is  a compresed version of a photo and is the most commonly used format, but there is little adjusting to be done to the photo after it is taken compared to a RAW image.

3.     TIFF : standard for publising and printing photos. A TIFF file can be compresed and not lose any quality buti it is larger than a JPEG file.

 

CCD (Charged Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) are two kinds of sensors cameras can use. These take the light within the picture and transform it through electrical sensors to present an image on the camera. CCD’s use the light and pass is through the chip and is processed and displayed. CMOS use a chip in addition to transistors to process the image. CMOS use less power and are much cheaper.

These are two pictures I took on my iPhone in Mykonos Greece this weekend. I am still waiting for my camera to come through customs!
