However, the JPEGs appear to have had a degree of noise reduction applied and some large-radius sharpening applied - meaning they don't have the same level of fine detail but the numbers have crisper edges. The XZ-1's JPEG output doesn't contain quite the fine detail that can be seen in the converted Raw files. These will be updated when the finished software is available. Raw files processed with a beta version of Adobe Camera Raw and may not represent final image quality. Save as a TIFF (for cropping) and as a JPEG quality 11 for download.Apply a Unsharp mask tuned to the camera, in this case 80%, Radius 0.7, Threshold 0.Set Sharpness to 0 (all other settings default).Load RAW file into Adobe Camera RAW (Auto mode disabled).Because Adobe Camera Raw applies different levels of sharpening to different cameras (this confirmed) we use the following workflow for these conversions: For a (more) level playing field we convert the latter using Adobe Camera Raw. On this page we're looking at both JPEG and Raw resolution. Nyquist is indicated in these crops with a red line. Therefore, even though it may be effectively unattainable with normal equipment in normal shooting situations, an understanding of a sensor's theoretical limit provides a useful benchmark for best possible performance. In theory though, a sensor without an AA filter, when coupled with a 'perfect' lens, will deliver resolution equal to its Nyquist limit. Anti-aliasing filters are designed to reduce unpleasant moiré effects, but in doing so, they also reduce resolution (the relative strength and quality of these filters varies from camera to camera). I found a cheap used Olympus XZ-1 in great condition so I bought it and I used the XZ-1 as my travel camera on my recent work trip to Chiang. This limit is rarely attained, because the majority of sensors are fitted with anti-aliasing filters. ![]() ![]() Beyond this limit (when talking about line pairs usually referred to as the Nyquist frequency) the sensor cannot faithfully record image detail and aliasing occurs. What we want to show here is how well the camera is able to resolve the detail in our standard test chart compared to the theoretical maximum resolution of the sensor, which for the charts we shoot is easy to work out - it's simply the number of vertical pixels (the chart shows the number of single lines per picture height, the theoretical limit is 1 line per pixel).
