Best Aperture for Landscapes using Micro 43 Diffraction is a problem because it softens the image and can destroy fine detail. The depth of field continues to increase as the aperture gets smaller, but you reach a point where diffraction sets in. As you make the aperture smaller (increase the f-stop) lens performance improves and the depth of field increases. When a lens aperture is wide open, the lens doesn’t perform at its best.
This may be necessary with a full frame DSLR, but not when using a Micro 43 camera. Typically, they will stop the lens down to a very small aperture for scenes needing a large depth of field. There is a common mistake amongst DSLR users who switch to Micro 43 (or a compact camera).
Fortunately, I was able to avoid this as I made very deliberate decision to expose the image correctly in camera. Had I needed to lighten the shadows for this image I would have to apply more damaging noise reduction.
#MICRO FOUR THIRDS VS FULL FRAME ISO#
Here the shadows have been lightened and noise is obvious despite the ISO being set to only 400. Magnified section of the image with the shadows lightened, revealing image noise. There are plenty of shadows here as the shot was exposed for the highlights in the signs. Look at the image below shot in Seattle’s Fish Market. Noise tends to be most evident in the shadow areas of the image and is often revealed if you lighten these. As you move your camera setting away from the base ISO, you reduce the sensors dynamic range. The base setting also allows the sensor to capture the greatest dynamic range in the RAW file, helping to reduce any clipping of highlights and shadows. This is base setting for this camera which means noise will be minimised. Personally, I tend to leave my Olympus EM5 set to ISO200. Higher ISO settings produce more noise so use a low setting whenever possible. Removal requires careful adjustment and care when sharpening (remember Tip 1 above). Noise reduction can soften your image and destroy fine details. Whilst it’s possible to remove the noise when processing the RAW file, it’s always better to avoid it. Learning to control and minimise this noise during image capture is important. Image noise is always present, but it isn’t as noticeable at lower ISO settings. Small sensor cameras link Micro 43 suffer more from image noise. These are the key areas dictating image quality for Micro 43 RAW files. Give special attention to manipulating image Tones, Reducing Noise and Sharpen your RAW files. Invest time to develop a processing workflow for your RAW converter. To produce excellent images from a RAW file you need to perfect your processing, and this is particularly true for Micro 43. This though only gets you into a good position from which to develop your photograph. You will have heard it many times before, but it needs to be repeated “Shoot using RAW format”. This article shares some of my tips to shooting landscapes with Micro 43 and other small sensor cameras. There are though limitations you need to know about and possibly work around. Ultimately the answer to the answer to the question is yes, Micro Four Thirds (Micro 43) can be used for Landscape Photography it even has some advantages over larger cameras. But what’s the answer? Is micro four thirds landscape photography viable? The discussion then goes on to argue the merits or otherwise of micro four thirds. One such link appears to have been triggered by someone at a filter company advising a potential company “the M43 system is useless for landscape photography”. One forum discussion (argument) appearing regularly is “can you use micro four thirds for landscape photography”. Often this reveals problems people have, giving me ideas for articles and tutorials. From time to time I explore how some of the visitors to Lenscraft find me.
