RAW file is when an image keeps most of the information from camera and isn't edited to fix or enhance the picture - sharpness and contrast, without processing and compressing. A RAW file needs to be changed to  JPEG to make it more convenient for printing and sharing.

JPEG file is a commonly-used. It is processed and compressed by the device according to the settings made by the device user before the picture is taken. It is very common and can be easily opened in most computers. 

These are two different pictures that I took in class last week. In the first picture the sky looks darker than in the second picture. This is because the ISO number and the amount of light that is let in while the picture is being taken. I used my Nikon D5500.

This photo was taken in Dublin, Ireland. I used my Canon EOS Rebel T3 camera.

A raw image file contains minimally processed data from sensors or scanners. A JPEG photo is the compressed version of a photo and is the most common format for storing or transmitting photos. TIF is that standard photo for publishing and printing. It can be compressed or uncompressed and is larger than a JPEG file. Both CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor) convert light into electrons. CMOS lenses are cheaper to manufacture.

This is my favorite photo of the week taken in Split, Croatia.

This picture is very over exposed.

I changed the ISO and the aperture and so the picture turned out less washed out.


I changed the ISO and the aperture again and the sky and buildings were given more color.

                                                DIFFERENT TYPES OF FILES:

When you take a picture with a digital camera you can chose to save the picture in different files. The different files are: JPEG, RAW and TIFF. The RAW file is the original picture and therefore the automatic saving of it. It contains minimally processed data from the image sensor of either a digital camera, image scanner or motion picture film scanner. The reason why it's called a RAW file is because they are not yet processed and therefore are not ready to be edited or print it. After the picture is taken, you have the choice to turn it into a TIFF or JPEG file to increase the its quality. Furthermore, if and when you convert the RAW file to JPEG, the picture can be easily saved and it is a faster, easier and more possible way of passing the picture around and be accepted by different types of computers. Instead, if you chose to save the picture as TIFF than the picture doesn't lose its quality, but it is a big file that require a lot of memory room.


                                                  SENSORS: 

The different types of sensors are CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor). The sensors capture the light that will eventually turn into a picture. In other words, once the picture is taken, the light that have been captured will be turned into electrical signals that will produce what we call a picture. The CCD's will pass the light through chips that will then process and become a picture. Similarly, the CMOS also captures the light and then create a picture. However, it is a more complex process where it uses a chip and transistors to process the light that will eventually develop into a picture. Although it is a more complex process, it is not the best. What I mean is that CMOS sensors are cheaper and the quality is not as good and professional as it is in the CCD sensors.



                                                         MY PICTURES:

I love taking pictures of flowers especially from close up. There is no filter nor flash, the sun is the only source of light used. I also love the contrasts between each colour, especially in the first picture. In it, you can clearly see the petals "in movement" and therefore you can see a bit of texture.

I decided that I would try and take a photo at night from an elevated position and this was the result. The picture was taken around 10 p.m. on Tuesday with my Canon Rebel T5. I messed around a little bit with the ISO setting and the aperture speeds to see what kinds of photos I could get and the results were similar to this.
