Ok we are back again and today we will talk about DPI (dots per inch). Dpi is quite important when you are making stuff in an image edit program. When you start an new document you always have to ask you the question; what is it meant for, Should it be high res or small file size?
What is DPI ?
To use Dpi correctly you have to know what dpi is. When you look at a poster through a microscope you may notice that large plains of color aren’t actually solid. The closeness of the dots gives you the illusion of a color. As the name suggest dpi are the amount of dots you will find in 1 inch (2.54 centimeters). When used in a picture this can add a lot or decrease a lot of detail.
The bigger the better ?
Yes and no. This depends on what you are gonna do with it. If this is meant for offset print you can go for 250 - 330 dpi. When you work with these dpi settings you will notice that the size of you document increases with it. So working 300 dpi images for web is a no-go. For web images you should aim 72 dpi (screen resolution). If you are simply working for your home printer a 150 dpi should do the trick.
If you have any questions depending DPI dont hesitate to ask.
