I still think the stock camera.app starts up the fastest and is the easiest to use.
- ProCamera and the stock camera app start up in the same amount of time on my iPhone4.
- The stock camera app is indeed easier, but that is just because it is more limited, so that's normal.
None of the other camera apps like ProCamera or Camera + take any better pictures IMO. They can claim all sorts of exposure and white balance features, but I've yet to see a noticeable difference.
- After switching from stock to ProCamera I have no more pink hue in the biggest part of my photos, thanks to the possibility to change the white balance and exposure.
- Before taking a picture you can change these settings and see the changes on the screen immediately. For example, if I open the app and point the camera to whatever I want to photograph but it is too dark, I move the yellow box around and can get a clean light picture. The stock camera app doesn't do this... You really have to aim the lens a hair to the left/right/top/bottom to have the stock app change these things, whereas ProCamera allows you to just 'point and click' to adjust.
All of this +
- built-in 'studio': add effects and whatever to your photos (somewhat 'limited' but a very good base)
- anti-shake mode: take pictures when the camera is still, so without movement
- grid guides and virtual horizon: to take pictures that are straight and horizontal
All really good features that actually help, for me anyway.
But for me, the camera.app remains on the front page...all the others in a "photo" folder.
I have a similar setup. All apps are on the front page but I have ProCamera as the standard app with all other photo apps in a folder right next to it for easy acces.
I have tried and used a couple of apps now: stock camera app, Pro HDR, CP Pro, Pano, AutoStitch, PS Express, ColorSplash, Photogene and ProCamera.
The stock camera app can produce nice photos as well, but HDR mode doesn't perform well for me.
Pro HDR is only good in manual mode, in my opinion, the auto mode produces some weird things sometimes.
CP Pro (Camera Plus Pro) and ProCamera kind of overlap, but I absolutely love ProCamera because of the reasons mentioned above.
Pano vs AutoStitch is difficult... Pano really helps you take the pictures and then makes them into a panorama, whilst AutoStitch doesn't allow you to take pictures but can transform anything in your photo folder into a panorama (Pano doesn't do this).
So my experience:
- For taking pictures: ProCamera produces the best photos
- For panorama's: I prefer Pano over AutoStitch, but not by much, each has advantages
- For editing: depends on what you want to do, I kind of use them all but Photogene gets used least.
But! I have to say my favorite photo I have taken with my iPhone4 so far was taken with the stock camera app without HDR. So when you do get everything to line up perfectly, the stock app sure can deliver.
Sorry for the long post, but I wanted to share my experience and opinion to those of you looking for a new or an extra app. I have been looking and comparing a lot myself and it's not easy sometimes, so hopefully this helps.
