PhotoAcute processes sets of photographs taken in continuous mode to produce high-resolution, low-noise pictures. It increases image resolution, removes noise without losing image details, corrects image geometry and chromatic aberrations and expands the dynamic range. Examples (on photoacute.com site): http://photoacute.com/studio/examples/mac_hdd/index.html FϿϻЎЏЌϿЍ ^ Index :: ^ Features IЇϻЁϿ ЌϿЍЉІЏЎЃЉЈ ЃЈϽЌϿϻЍϿ ϼϿГЉЈϾ ϽϻЇϿЌϻ ϽϻЊϻϼЃІЃЎЃϿЍ PhotoAcute produces a combined image from a sequence of continuous photographs, thus acquiring more graphic information than is available from any one photograph. Using sophisticated proprietary algorithms, it combines the individual frames to produce one large- sized and high-quality image. This kind of technique is usually called "super-resolution processing". Unlike digital zooming and image sharpening, the photographs produced by PhotoAcute do really have higher spatial resolution. Small, thin and far-away objects, traceries, textures and inscriptions become recognizable. PhotoAcute super-resolution algorithms are tuned for particular camera/lens models to achieve maximum quality. 17/01/2019 PhotoAcute Users Guide https://www.photoacute.com/studio/guide/guide.html 3/18 source photograph (one of a set): camera resolution was not enough to capture the brickwork pattern strong sharpening does not reveal more details super-resolution applied to the whole set of photographs: the pattern is much more apparent, as if it was captured by a camera with higher resolution sharpening applied to the result of superresolution processing - for comparison with the sharpened original Usage: To perform Super Resolution processing turn on the Increase Resolution option in the processing options pane.. Superresolution processing depends on a camera profile for the given camera model. It is highly recommended to use high ISO levels (e.g. 400) for super-resolution processing. Cameras automatically use long exposures when ISO is low, and this leads to handshaking artifacts that can significantly decrease the level of detail of the picture. At the same time, the noise caused by high ISO can be efficiently reduced during super-resolution processing.

It produces an image that otherwise could only be taken with a camera that had much wider dynamic range. This feature becomes especially handy for objects photographed on back-lit background (e.g. window, a light snow, direct sunlight), or scenes that have important details in the shadow. 17/01/2019 PhotoAcute Users Guide https://www.photoacute.com/studio/guide/guide.html 4/18 PhotoAcute introduces advanced HDR blending techniques: a precise radiometric alignment for producing consistent HDR images of scenes with moving objects and varying illumination; and "Noise-free HDR" to get rid of the noise in shadow areas of HDR images. highlights captured, shadows lost shadows captured, highlights lost both shadow and highlight details are visible Usage: Dynamic range expansion is turned on/off with the Blens HDR image option the corresponding checkbox in the processing options pane.

The classic way to extend depth of field is to take images using a narrow lens aperture. This solution has two serious disadvantages. Small apertures bring more light diffraction, degrading the image resolution and they reduce the light transmission, forcing the use of longer exposures, which leads to motion blur in the pictures. Also, even using the smallest aperture is sometimes not enough to capture the entire scene sharply. The alternative way is to take several frames of the same scene with different focal lengths. Each of these images has its own depth of field and they can be merged together, combining focused areas of each 17/01/2019 PhotoAcute Users Guide https://www.photoacute.com/studio/guide/guide.html 5/18 image and producing a resulting image with cumulative depth of field. Using this technique is essential in macro-photography and micro-photography as well as in all situations when the very near and very far objects in the scene have to be captured acutely. Usage: Turn on the Focus stacking option in the processing options pane. ^ Index :: ^ Features CЉЌЌϿϽЎЃЉЈ ЉЀ ϽЂЌЉЇϻЎЃϽ ϻϼϿЌЌϻЎЃЉЈЍ Every lens focuses the light of different wavelengths in different positions. This causes chromatic aberration that is seen as "fringes" of color around the image. PhotoAcute corrects this aberration, minimizing the circle of confusion. The correction is performed automatically, with no need of manual adjustments of any parameters. source photograph color fringes resulting photograph Usage: Color fringing correction is turned on/off with the Fix chromatic aberrations option the corresponding checkbox in the processing options pane.

The main problem of noise reduction techniques is that the more noise is reduced, the more image details are lost. This becomes extremely apparent in the low light scenes (e.g. night photos or shadowy parts of the scene). 17/01/2019 PhotoAcute Users Guide https://www.photoacute.com/studio/guide/guide.html 6/18 PhotoAcute provides high noise reduction without losing the image details. source photograph (one of a set) a photograph processed using the noise reduction utility (one of the leaders on the market) whole set, as processed by PhotoAcute with NO super-resolution Usage: Noise reduction is performed automatically when stacking the images.

This gives photographs the right perspective and a natural look. Usage: Geometry correction is turned on/off with the Correct geomerty option in the processing options pane. This feature requires availability of a profile for the given camera/lens combination. FЃЌЍЎ-ЎЃЇϿ ЏЍϻЁϿ: ЍЎϿЊ-ϼГ-ЍЎϿЊ ЃЈЍЎЌЏϽЎЃЉЈ 1.
