New version of PhotoAcute released, featuring new super resolution profiles, including Hasselblad / Leaf Aptus 17:
Release notes on PhotoAcute forum
Panasonic features so-called Intelligent Zoom mode in Panasonic Lumix LX7 camera, claiming that with their “Intelligent Resolution” technology 3.8x optical zoom virtually extends to a 7.5x equivalent.
It sounds as single-frame super resolution, so we decided to take some test images to see how good is it.
Below: 3.8x versus 7.5x zoom
100% Crops. Top: 3.8x zoom, bottom: 7.5x zoom (with Intelligent Resolution)
As we can see, Intelligent Resolution does not add more details (so the resolution is not increased). The same result can be achieved with extra sharpening. See below a comparison between “Intelligent” zoom and bicubic upsize + unsharp mask filter in Photoshop:
Conclusion: Panasonic Intelligent Zoom (or Intelligent Resolution) delivers sharper images but does not provide higher resolution and in no way can compete with optical zoom.

Camera became one of the things (if not the only one) that really make the difference in modern smartphones. Among the leading OEMs such as HTC, Sony and Intel who emphasize their new advanced camera features, Huawei offers something really unique – SuperZoom feature, allowing to take high quality images when zooming in with a mobile phone camera.
We had a chance to test SuperZoom feature with Huawei Ascend P2 phone at Huawei’s stand at Mobile World Congress. In brief, it works incredibly, see the pictures below.
Conclusion: SuperZoom is a revolutionary technology providing zoom quality comparable to optical zoom, on mobile devices!

Your camera captures the details, HDRAW makes them visible
The maximal dynamic range – the contrast between the brightest point and the darkest one – of a JPEG image is about 4,000 times lower than the range seen by a human eye. A camera captures several times higher dynamic range than one available with JPEG. This means that the range is either cut or squeezed in JPEG photos, therefore in high contrast scenes the details in highlights and shadows are lost, as well as the details of low-contrast objects. RAW images still contain the full dynamic range captured by the camera.
HDRAW utilizes Tone Mapping technique, allowing to preserve the details while fitting high dynamic range image into the limited dynamic range of JPEG or any other 8-bit format. Exploiting the properties of the human vision, HDRAW makes the picture and color details visible in all areas of the photo from the darkest to the brightest one.
HDRAW is a single-image HDR tool that utilizes higher dynamic range available in RAW.
RAW made easy
While usual RAW development process is a sophisticated task that requires adjusting a lot of parameters in a RAW converter, HDRAW is intended to produce rich detail images virtually in one click (ok, three clicks actually). It still allows you to adjust tone mapping parameters, but the standard presets are enough in most cases.
Along with HDRAW application we’ve launched HDRAW.net community for photo sharing, discussions, etc.
HDRAW is available at introductory price of $14.99. Registered users of PhotoAcute can use HDRAW for free – HDRAW accepts PhotoAcute 3 registration codes.
Unlike the other cameras that take an image after you tap the shutter button, Pix Fix keeps taking the images until you tap the button.
So, the meaning of the Button is now “Stop! That’s a wrap!” instead of “That’s the moment, ooops I’ve missed it”.
After clicking the shutter button you have a series of photos taken before the click. You can then pick the photos where the moment is captured or save the whole series.
We’ve implemented a real-time SuperZoom demo on Samsung Galaxy Nexus. As far as we know, that is the only real-time implementation of super resolution technology in the world
