SLR vs Compact (Fixed Lens) cameras


SLR Cameras:
Advantages:

·         Normally better image quality which stands out indoor or in low light compared to small compact cameras
·         Provides to ability to control Depth of Field (or selective focusing) to keep certain things in focus everything else out of focus. The kit lens are limited in this capability but you can achieve greater control with fast or wide aperture lenses.
·         You can change lenses and use many accessories like external flash, remote control, filters, extension tubes, macro tubes etc.
·         Better build, better life.
·         Normally they offer lot of manual controls
Issues:
·         Bulky and difficult to carry around
·         Normally expensive. Accessories like lenses etc can also cost significant money.
·         In good light or in outdoor use, there is not much advantage unless filters are used.
Compact Cameras:
Advantages:

·         They are cheaper.
·         Easy to carry around. Compact in size.
·         You can get tremendous zoom up to 60x in some of the cameras. This comes vary handy in outdoor photos and in travel. It is difficult to get this kind of zoom in SLR cameras.
·         In outdoor, good light, they are as good as any camera. They work great in landscape cameras or in situations where you want most things in the scene in focus.
·         Compact cameras offer macro shots. In macro mode, camera can focus on things very close to camera. To get similar ability in an expensive SLR, you will need a dedicated Macro lens. By nature, compact cameras offer great macro photography.
Issues:
·         Many models do not offer enough manual controls
·         They struggle in low light or in indoor photography
·         Don’t have options to use many accessories like different lenses, filters, external flash etc.

·         It is difficult to achieve bokeh or background blur with small sensors and tiny lenses.

Camera comparison iPhone5 vs iPhone6

Looks like in Auto mode (without any setting), iPhone5 and iPhone6 have more or less very similar picture quality. One noticeable difference is that iPhone6 camera is more wide angle.
Here is a photo taken with iPhone5:

Photo with iPhone6
Besides being wide angle, looks like iPhone6 lets you control exposure right on the screen. Tap the screen and a metering circle will come up with a + sign. Touch it and it it will let us increase or decrease the exposure. The cool part is you will be able to see the impact of it live on the screen so you can decide which exposure level to use.
If you have just iPhone5, don't worry. You can still set us exposure by touching various parts of the screen. Touch a darker object/part in the screen to make the photo brighter or touch a brighter spot on the screen to make the whole photo darker. For details, please see my last post.
