Steps on how to remake those fancy tumblr and Instagram accounts
Step 1: Snap!
Take a good picture, eye catching yet simple, but make sure to turn on HDR if you have an iPhone for the best results!
Step 2: Effect
This app is called Pixlr Express+ and all you have to do is choose the effect Salomon
Step 3: Contrast
To make the tumblr effect, adjust contrast to 20 and there's your tumblr picture!
Step 4: Step Ahead
The app is PicsArt
To go even more tumblr, find a good transparent or overlay and crop only what you want in the picture
Step 6: Play Around
Play around with your options, and USUALLY it will become a picture you want without the background (it has to be plain) most of the time darken, lighten or multiply.
Step 7: Squaready
To fit your picture on Instagram, use squaready for a square frame
Add all the stuff you want, now that you've learnt the basics, take your chances! :)
