Photostitch
So I tried out the free version...then ultimately decided to buy the full version (i was at a store and was holding a drink and my phone...i put down the drink and bought the app...kinda funny how i used to just buy drink that costs $3 no thought about it and when it comes to a $2.50 app i get indecisive..)...so my review on the panoramic shots...
in the app the picture is out of focus when i am taking the shots. it makes me uneasy (no way to fix it)...the actual pictures though are in focus. right before it takes the picture the camera does focus. As long as u make a decent attempt to line up the pictures with the ghost/shadow image they stitch together very nicely. There are some pictures i have taken that have noticeable light difference (looks as if there is a huge shadow casted). The free version was fine, but the paid 5 shot stitched 180 degree shot is amazing.
Overall, if you want panoramic pictures, get photostitch. it's only $2.50. Thats NOTHING. Yes, the pictures arent perfect, but they are great for what you're paying. Highly recommend. Just dont get too edgy about the unfocused view, it will focus for the pic.
One note to know. This is a very big down side to this app. I just thought of it as i was ending my review. The app doesn't quit unless u go into running services and force close it manually. Hate that part. Worth the hassle though.
