Sensor noise comparison

This post is my take on sensor noise vs sensor size, this is not a scientific experiment, more of an understanding of how a sensor’s size has an impact on noise (Luminance and Chrominance) across ISO settings when the exposure is either under or over. I have produced this mainly for the purpose of deciding if I can work with the 1″ sensor and full frame, and ditch the Four Thirds kit.

I have used several cameras for this testing, with sensor sizes from full frame, APS-C, Four Thirds and 1″, with the following cameras.

All of the cameras were set to Program Mode, with Matrix or equivalent metering, and auto white balance. The images captured starting at the base ISO for the camera (for both the Olympus and Fujifilm the base ISO is 200) and then increasing the ISO one stop up to ISO 3200, I then bracketed the exposure by plus and minus 3 stops. The RAW files were then imported into Lightroom with default settings with no sharpening or noise reduction applied, I obviously had to correct the exposure compensation by adding or subtracting the 3 stops. All of the images were then exported to jpegs for sharing with this blog page.

For information, all of the images were captured indoors on a cloudy day with diffused light through the window blinds. The reason I chose to use two types of camera with an APS-C sensor, was to see if there was any difference between the Bayer and the X-Trans array.

I would also add that in real life situations the noise may not be apparent in the image, or some may find it adds to the image, it really depends on the subjects matter or type of photography that you follow. Continue reading


What’s in my bag

What's in my bag

Lumia 930 4.46mm @F2.4 1/50sec ISO 64

I am a big fan of these type of posts as I am interested in the technology, as well as the art of photography. So this is what is currently in my bag (that should be bags, as I don’t have one large enough for all my gear).

My cameras of choice are the Olympus OM-D series, the Sony A7R and the RX100 II. The Olympus OM-D series cameras are very customisable and are full of very useful features, the Sony’s are not so customisable, but do have the larger sensor. Although I have chosen both manufacturers for different reasons, ultimately I chose them both for their image quality and portability. Continue reading

The journey begins

Well here goes my very first blog post, the reasons why I started this and what I plan to do with it.

I have been meaning to start this blog for some time now, in fact, it was a New Year’s resolution but I kept putting it off until now. I have been a photography enthusiast since I can remember, borrowing the family camera for a school trip or holiday, until finally investing my hard earned money in purchasing my first SLR camera a Zenith EM. My second camera was much better, an Olympus OM-10, and I still fondly remember it, very compact especially with the only lens I owned, a 50mm Zuiko F1.8. So this blog will be my thoughts and actions while wandering ‘through life with a camera’. Continue reading
