I am one of those people that LOVES taking pictures on my phone and I have tried just about every Photo and Panoramic app on the Play Store. I had a iPhone 4 before I switched over to S3 and at the beginning I was scared because I was letting go of some really good photo apps.

Now though, I think I might have found the ones that fit my photography style perfectly.

1: Magic Hour. Think of it as instagram with unlimited filters. It has a "Filter Store" where you can download other filters that people have made using the app. There are THOUSANDS of these. Thankfully you can search by newest, most popular, etc. This is like Instagram on crack. LOVE IT! Also, if you run a photo through Magic Hour and save it, then weeks later you want to run another photo through the same filter but forgot which it was, you can load up the photo you saved and it'll figure out which filter was used and you can throw that on to another picture. You can also mark filters as favorites, etc

2: Perfectly Clear. With just one button this app will make your photos look so much better. They had this one on the iPhone as well and I'm glad it carried over. It fixes saturation, contrast, color, brightness and it does it all better than any other app I have found

3: TouchReTouch. Sometimes you take a great photo and happen to notice after the fact that there is something in the background or powerlines you wish weren't in the photo. With TouchReTouch you just highlight want you want removed from the photo and it smartly removes it. It is a lot like using the smart eraser in Photoshop except you can do it on your phone.

4: AfterFocus. After focus simulates what a DSLR camera can do where the foreground is clear and then the background is blurry (not in focus). You just use your finger and select the foreground, then select the mid ground (optional), then select the background. It will then very realistically blur the background so your picture gets a great DSLR look to it.

Usually I'll take a photo, edit things out of it I don't want with TouchReTouch, then depending on the photo I'll run it through AfterFocus to get the DSLR look and then Perfectly Clear to make it look the best possible. Finally, depending on what I want the photo to look like I'll apply a filter. And if things go ok then I get pictures like this: http://trukatu.com/baby.jpg

As a bonus, I should mention that HDR Camera+ is one of the best HDR apps. Most HDR apps takes 3-4 pictures and combines the brightnesses to make one awesome looking pic. But they all require you to remain almost perfectly still. HDR Camera+ is the only one that takes multiple photos, analyzes the brightnesses and combines that all over the first image only. So even if the subject moves or your hands moves or something, it still looks great.
