Well..like my title the more the merrier...the more you learn..the more you know...jokes apart...we were learning more about photoshop.
We mainly focused on pixels. This one piece of data on your computer image. If you look closely at a picture by zooming in you can see that there are many pixels, infact thousands..Each of these so called pixels have a code we know as a hexadecimal code.Changing the amount of pixels in your image changes your image little by little..depending how many times you change it.
There specific amounts of pixels that are suited for different roles. For example when you need to print a good amount of pixels would be 1800 by 1600. To post on the internet or to send to someone by attaching it to them 72 by 72 pixels.
This done because reducing the amount of pixels reduces the size of your image making it easier for you to do stuff.
Do keep one thing in mind though, it maybe neat but each time pixels are changed the less detailed your pictures become..so not that clear. Another important factor is that when you are increasing pixels from a small size image...your image will be blurry because the computer works with amount of pixels at present. Only codes are thought up by the computer to increase the pixels...since that was your command . Computer follows commands..they don't have their own opinions..they do what you say like a pet..
While..when it comes to decreasing the amount of pixels in your image..pixels that are not needed are thrown out!
Something else that we focused on was cropping.Which is when you take the part of the picture you want and make it the whole picture cutting out evrything else not selected..
As well as levels..these are things you can really enjoy playing with. You can change the levels of the colours red, green, blue...Doing this makes the image...bright and light or dull and dark. This edits the picture according your tastes..
