v. BASICS

one. USEFUL APPS

i. PICSART

for editing. you can make covers, moldboards, manip and even gifs ( i'll post the tutorial soon ). it is the only app i use for editing picture, it's really good and easy to use.

ii. POLARR

for filters. it's the best app that has filters in my opinion. there are so many books here about polarr filters including mine, so go and check them out.

iii. PINTEREST

for picture. it similar to Google but it has a better picture with good quality.

iv. VSCO

for filters too, but I rarely use it. it's good and has nice filters but personally, I prefer polarr.

i hope that i help you
enough with the apps
