Cameras, and beyond…


In the past I have used a variety of cameras, xxx, Olympus OM-1, Sony ….(and I still have them). 

However today I have no intention to be anything else but a tourist photographer. Form my family and tourist photographs I use either a … or my iPhone 6.


So I suppose the real question is about how to best use what I’ve got, and what extra is out there in terms of both hardware and apps.




iPhone 6 




Native features

Bursts - don’t miss the idea photograph, keep your finger on the Camera trigger and shoot a rapid series of photographs automatically. 


JPEG is the default file format used by the iPhone. RAW is available with some camera apps., but not (yet) with iOS.

RAW stores more information than JPEG. However some authors have noted that the difference in quality is not so big since Apple applies some algorithms to improve the JPEG image when stored. 

I understand that Photos in OS X can digest RAW files. Under Photos - Edit Photo, I am told that “RAW” is included in the photo title area. 


High Definition Range (HDR) is an option in Camera, with On, Off, and Auto. The HDR option actually takes three different photographs, one immediately after the other. The first is what might be called “normal”. The second is adjusted to capture best the highlights, and the third is adjusted to capture best the shadows. These three images are automatically joined together to create a single image stamped with HDR. The HDR should have better colours and contrast. 

By default, both the “normal” image and the HDR image are then stored. In Settings - Photos & Camera - Keep Normal Photo, you can decide to only store the HDR image. 


Horizon and Rule of Three - In Settings - Photos & Camera - select Grid ON 


Focus and Exposure - Touching the screen at the place of the principle subject of the photograph will open a small yellow-framed square, with a small yellow sun icon next to it. The focus and exposure will be adjusted on what is found in that yellow frame. The square and associated sun icon can be moved around the screen by tapping again on the screen. After a short period of time the yellow frame and sun icon will dim, and then disappear. If you keep you finger on the screen location for a few additional seconds the message AE/AF Lock will appear. Now the yellow-framed square will remain at that location of the screen no matter where you point the camera. Tap again of the screen and the option will disappear.

In addition, by moving the sun icon up or down you can change the exposure.  

This focus/exposure option can also be useful when taking portraits, or when you which to focus on a foreground object in a landscape. Equally a very luminous landscape can block out detail in the sky or in vegetation. Adjusting the focus and exposure can help open up a photograph bringing out detail such as clouds and subtile variations in blues or greens. Another use is when many of the colours in the photograph are similar (e.g. lots of sandstone tones in a monument). Increasing the exposure on a darker area can brighten up the whole image, and widen the tonal variations in the stone or brick. 


Geolocation Is fantastic since it tags each photograph with a location. To active go to Settings - Privacy - Location Services (On) - and active Camera with “While Using”. 


Panorama - the default is to scan from left to right, but tap on the arrow and it will invert to a scan from right to left.  


Note: The “sensitivity of the film” of the iPhone 6 is set at ISO 400, but it can be changed using a third-party app. However the aperture (i.e. f-number) cannot be altered.
