In this blog i will be talking about some details of file formats and the importance of high resloution in pictures.

First is Jpeg:


Now this is a Jpeg File.
Jpeg is the most common used file format, Most digital cameras upload pictures as Jpegs, Once you are finished editing a picture on photoshop you will usual save the picture as a Jpeg.
Jpegs can be low qualty or High qualty depending on the resloution.
If you zoom in on a Jpeg the qualty will get lower and lower and you can start to see the pixels in details.
One big con with jpegs is that once you save a picture as a Jpeg in photoshop, you can not go back and edit things in the picture.
for example if you add layers to the photo, then save as a Jpeg and try to edit the saved Jpeg, you will not be able to change the layer you added before.

Now for GIF:
GIF files are pictures that are little animations.

Love heart animation ( note wont show up on the site so i have set a link )
http://img.photobucket.com/albums/v491/egan_87/heartalways.gif

This animation is about 5 seconds long and isnt high qualty.
You can creat GIFs using programs like photshop.
Unlike Jpegs GIF resloution cant go that high.

Finally PSG files.
A PSG file is a photshop file that has been saved so it can be opened again.
So you can change layers that have been added and little details such as healing tools.

Resloution:

The higher the resloution the better the qualty.
So for example:




This pictures resloution is 500 X 375.
Thats 500 pixels across and 375 pixels down.
Its a smaller picture but if you zoom in you can see the less qualty details.
Also the higher the resloution in a picture, the larger the file will be.

Time for a High resloution picture:

This image of one of my new kittens is 2015 X 1512.
This is a higher qualty picture that hasnt been edited in anyway.
Of course with its high resloution it is a larger file, this is close to 1MB.

That is a quick overview of file formats and resloution, my next blog will be about the rest of the pictures i hav took.
