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.

The Wow Factor – Listening for Sound Quality

Following this week’s posts of phone photos from Fforest and the issues that go along with the processing of them for use in a StillWalks video, I have now reviewed the sounds recorded on my phone from the same walk and for me, this too leaves something to be desired. Below is a sample clip – towards the end of it there is some lovely birdsong!

I used the free RODE app for the recording but not the mic they make to go with it. Much as I would like to have one of these, the main purpose of my trials with phone photography and recording is to assess the quality that can be produced at the basic (free) level and compare it to using StillWalks’ higher end equipment.

I have finished going through the images for a StillWalks video and based on them alone, I would suggest that the finished product will be best viewed on a phone or tablet. The sound, however, may be more of a problem. It is likely that most people would not be aware that the sound quality is not up to scratch and that is understandable and no fault of anyone’s.

It comes down to what I call the “Wow Factor”. It is easy to accept lower quality in something  if you have nothing to compare it with. However, the better the quality, the greater the impact or Wow Factor – whether it is recognized as such or not.

It is probably the sound that does most to take you to the location of a StillWalk and so it is important to me to do what I can to ensure this is as good as I can get it. The proof, as they say, will be in the pudding! I will post the finished video on the blog when it is completed and you can judge for yourselves.

Quality Walks

Misty Walk is a new stillWalk which was actually produced at the end of last winter. There are several more StillWalks in the pipeline but it has proved difficult this last year to complete the post production on these. This is largely because of the project work I have been doing – see Projects.

I have uploaded two versions of the Misty Walk to the Winter Walks page. Both are high quality but one is in HD (720p) and the other is small scale at 480 x 270 pixels. (see also below).

StillWalks should be viewed, if possible in full screen mode and these videos will show the difference between the two versions. The HD button is in the top right of the first video and the full screen button is on the bottom right of each video.

It was supposed to be a dry, sunny day for this production but it turned out otherwise! This misty walk is on Ryer’s down on the Gower Peninsula in South Wales and was very enjoyable and atmospheric (small scale). Walk location
