More photos from my iPhone using both the phone’s Camera app and PureShot.
Controlling exposure and white balance can be difficult in certain situations, most especially when there is significant contrast in light within the frame. One way to adjust this with the Camera app is to try out different angles and points of focus until you find a reasonable compromise and then make further adjustment to shadows and highlights in post processing with an app like Adobe Photoshop (the phone version) or Lightroom on your computer.
PureShot allows easy adjustment on screen of the area within the frame that is sensitive to the light when taking your shot. This means that it is much easier to use the angle and composition that you want with little compromise to white balance and contrast. And of course further tweaking is possible in post production. I like the mobile Photoshop app for post production on the phone but another good app I use is SnapSeed.
The first photo (of The Great Glasshouse at NBGW) was taken with the Camera app. Although there was significant contrast between the light coming through the glass roof and the “landscape” inside, it was easy to adjust the angle satisfactorily to allow a good distribution of light or white balance.
The second and third shots were both taken with PureShot as TIFFs, with its exposure control making it possible to handle the contrast between sky and land and inside the glasshouse, “table” and darker plants surrounding it. For detailed info on using either app, I refer people to Emil Pakarklis’ iPhone Photography School.
