Differences between JPG, PNG, GIF, RAW, & TIFF

JPG is a file format used for photographs. It works by analyzing the image and getting rid of any information that wont be noticed by the eye. You can adjust the compression of a JPG file.

PNG is a storage format that is lossless. This means it looks for patterns in the image it can use to compress the file into a smaller file size , which can be reversed to recover the original image.

GIF makes a table of 256 colours from any 16 million colours. It will use an algorithm to make an image that is optimum. It may use the nearest color to represent each pixel, and it can also use error diffusion to correct the pixels.

RAW is a image format that is available on some digital cameras. It is a lossless format, but is smaller in size than TIFF files which aren't compressed. Each manufacturer has their own RAW format, so you would have to use the manufacturer's software in order to view the images captured..

TIFF is a versatile format that can be lossless or lossful. Primarily use as a lossless format. TIFF images are not usually compressed, which consequently leads to a big file size.

Project 2: Collage, Silhouette and lettering

Image
In this project, we were supposed to make a collage of images about a person inside of a cutout of that person, and also make an outline of that person that describes said person. The objective of the lab was to see if we could use what we learned so far, it was to get us more familiar with things such as masks. Collage: I started by duplicating the picture of the person, then I made a selection of the person I chose. I would delete the person. Now I would import the images I was using for the collage. I would drag the images below the cutout, using the layer’s tab on the right-side panel. Then I would align them and save. Outline: I started by duplicating the picture of the person, then I made a selection of the person I chose. This time I would go to Select>Inverse, this allows me to delete everything except the person. Now I would go back and do Select>Inverse again, to select the person. Then I use the Horizontal Type tool to write 4-5 things about the person. Now double...

Project 3 : Restore Old Photograph

Image
   In this lab we were supposed to edit a damaged image with the tools we used in lab 8 which were, spot healing tool, healing tool, patch tool, etc. The objective of the lab was to teach us how to use tools to fix an image that was damaged. I completed this by using the healing tool to get rid of the damage in the background. I then would go and fix the bottom of the picture with the blanket or something similar, for this I would use the patch tool, healing tool, and spot healing tool. Then I would use the same tools to work on the colour damage. After that I started work on the eyes, and then finished the hair.    We used Adobe Photoshop CS6. This is relevant to web design because we may have to fix images in our line of work depending on the way we work and what type of work we do. I see myself using these skills to fix images that I need to use for a webpage or just as a business in general.

LAB 7 : Filters

Image
   In this lab we were supposed to use two images, make 4 duplicates of 1 image and keep the single image of the other, and then we were suppose to apply different filters to them. The objective of the lab was to teach us how to use the filters properly. I completed the task by making a new file that is 800px by 600px with a resolution of 400. Then I placed the 2 photos I chose, and duplicated one of them 4 times. Then I arranged them in a 2x6 grid. I selected the first picture, went to Filters>Filter Gallery>Artistic>Cutout, then adjusted the settings clicked OK and moved on to the next copy (Right of the Cutout). I went back the filter gallery and went to the Distort drop menu and used the Glow Diffuse adjusted settings clicked OK and moved to the next copy. For this copy go back to the Filter Gallery and this time go to brushed strokes, and use the Angled Strokes filter adjust settings, and click OK. Next copy will have the glowing edges filter, so we go back to th...
