Witch Hazel – Keeping Information (Lossless and Lossy formats in iPhone Photography)

That new app I have on my iPhone (PureShot) allows HI_Quality and MAX_Quality  jpeg photos and also TIFF lossless photos. The TIFF format in this case is not only lossless but is dRAW which means there is no in-app post processing done and no compression applied.

For those of you unaware of the ins and out, ups and downs of formats in photography, suffice it to say that the JPEG format takes away information gathered by the camera to a greater or lesser extent, thus the photographic information is compressed. TIFF is a lossless format which, although giving bigger file sizes, means there is no loss of information and, therefore, greater control for the photographer over how the finished image looks as well as (theoretically) a higher quality of image (at least in terms of the number of pixels used).

The image of the Witch Hazel below was taken in TIFF dRAW format and the close up of another Witch Hazel in the Botanic Garden of Wales was taken in JPEG format. Obviously you cannot make a straight comparison between the two formats here because the images are different but one thing I would say about the PureShot app and the Apple Camera app is that whilst it may be true that PureShot allows more control at the shooting stage (and I was very pleased with the results I got with PureShot), the Camera app is also very good.

There are many things that need to be taken into consideration when taking photographs but as far as the kit and applications are concerned, having a decent lens is probably the single thing that makes the biggest difference. Apple (and I am sure other high end smart phones with which I have no experience) made the right decision when they installed a decent lens in the iPhone.
