Helicon Filter, often referred to as Helicon or as Filter, is a proprietary commercial and freeware photo editing software program for Microsoft Windows, similar to such programs as Adobe Photoshop and the open source GIMP, developed and published by Helicon Soft Ltd. Helicon Filter's interface differs from other programs in that toolbars and menus containing edit options are replaced with labeled "filter" tabs, each containing some labeled edit options. Although beginners who don't recognize the standard icons generally find this helpful for getting around the editing process, some editors used to Photoshop-style programs may initially find this layout to be more confusing than the standard toolbar layout.

[edit] Overview
Helicon Filter, formally Helicon NoiseFilter, was introduced in August, 2004 as Helicon Filter 1.61 Beta 2. By 2005, Helicon Filter had become known for its noise reduction ability,[1] though it also had some other basic features such as RAW support, exposure correction, color adjustments, red eye removal, and resizing/cropping.[2] More recent versions of the program have yielded more advanced features found in Photoshop CS2 including cloning, selective color editing, and HDR imaging, though Helicon Filter still lacks other features found in Photoshop such as layer support, full selective editing abilities, and the ability to create graphics. The program runs in English, Russian, German, French, Spanish, Dutch and Italian.
[edit] Designers
Danylo Kozub (also written as Danilo or Dan Kozub), Ph.D. in Economics, is the chief project administrator at Helicon Soft Ltd., based in Kharkov, Ukraine.[3] He and his team of programmers, Stanislav Yatsenko, Vitaly Khmelik, Jury Shapoval, Vitaly Chentsov and Alex Zubchenko, produce regular updates to Helicon Filter.
[edit] Licenses
There are different license types for Helicon Filter. The differences between the licenses lie in the program's functionalities, speed, and allowed updates. Licenses may be used on a maximum of four computers.
Helicon Filter Free is the free version. It has most functionality of the commercial versions, except images can not be stacked, files can only be saved in jpeg or bmp, and it can only be used in simple preview mode, resulting in the removal of the Aberrations filter and some advanced controls, such as equalizers, some sliders, and some brushes.
Helicon Filter Home costs $30 for a current version license or $60 to allow future updates. It contains the program's main features but can't be opened as a plugin for other programs.
Helicon Filter Pro costs $20 for a one year license, $40 for a current version license and $75 for an unlimited update license. It can be opened as an 8BF plugin from some programs.
Helicon Filter Pro (MP) costs $60 for a current version license or $105 to allow future updates. It allows multiprocessor support, which, on computers with multiple processors, increases the program's otherwise slow processing speed by about 40% to 50% for every additional processor.[4]
[edit] Functionalities
Live preview
Helicon Filter's live preview can be used in either simple mode (all versions) or expert mode (commercial versions only). Simple mode allows the user to control aspects of the picture with fewer sliders, fewer brushes and no Aberrations filter, while expert mode gives the user more sliders along with equalizer control. Live preview can be used to show the final product or can show a split between the edited version and the original. Images can be viewed at various pre-set sizes with a scroll bar in most tabs, though custom zoom can't be set. In most filter tabs, a magnifying class can be used to view portions of a picture at 100%, 200%, and 300% magnification. In some filters, an "edit map" can be used to view which areas which will be affected from those filters.
Plugins
Helicon Filter supports plugins designed for Photoshop (in the 8BF file format), though many of these do not function in Filter.
Image stacking
In Helicon Filter Home and Pro, one is able to stack several images of the same subject for different uses. Firstly, High dynamic range images (HDR) can be created using the Increase dynamic range command. Secondly, the program is able to stack several images with high noise levels into one low-noise picture. Finally, the program is partially capable of stacking images of a moving subject together to create effects of time-lapse or multi-exposure photography to capture such things as moving stars, however Helicon Filter cannot spread out the frames to amplify a subject's motion (e.g. landing bird, flipping gymnast) or create GIF movies from these images.
Noise reduction
Image noise and grain can be controlled in the Noise filter using the Noise level, Highlights, Shadows, Radius and Chroma sliders. An equalizer allows selective effects by color. Helicon Filter's noise reduction ability is one of the program's highlights and has led to much publicity. It is considered on par with such noise reduction programs as Neat Image and Noise Ninja.
Brightness
The exposure and lighting of a photograph can be improved using the Contrast, Gamma, Exposure, Local contrast, Highlights, Shadows, Black point, and White point sliders. An equalizer to control effect by color, along with Haze compensation and gradient haze compensation sliders, appear in expert preview mode.
Colors
In the Colors filter, an image's white balance can be adjusted through color sliders or by selecting an area of the picture that should be white or match a predefined "memory color". Equalizers control spectral sensitivity and saturation by color. The brightness, hue and saturation of a color range can also be modified in a process often referred to as color swapping.
Aberration Removal
In expert preview mode, chromatic aberrations can be removed in the Aberration filter by selecting an aberration color and adjusting the Radius, Brightness threshold, and Color tolerance sliders. This filter works by taking all areas in a picture with the defined aberration color and reducing its saturation to zero. Since purple fringing, a common aberration type, is easiest to remove, purple is by default the aberration removal color. Optical aberrations, such as red/cyan fringing, are more difficult to remove and often must be cloned out in order to remove them completely.
Sharpening
In the Sharpening filter, sliders allow for the sharpening of both small details and edges. In expert preview mode, an equalizer can be used to sharpen specific colors and leave others unchanged. White halos can also be suppressed when sharpening.
Distortions
In the Distortions filter, barrel or pincushion distortion can be controlled, horizontal and vertical perspective may be changed, the image may be stretched and squeezed, the image may be skewed, h-bend can be controlled, and vignetting can be corrected. This feature is especially useful for photographs taken with a wide-angle lens, as this often produces distorted images. Complete image flips and rotations of varying degrees may also be done.
Resizing
Helicon Filter allows for cropping and resizing of an image. The image may be sized by custom pixels, pre-defined print sizes and DPI, special cropping for mobile devices or for the web, or as a percentage of the original image size.
Frames
Frames and text can be added to an image using the Frames tab. The frames can be colored as a function of the actual image or as a solid color, and various types of frames are available. Text may also be inserted in this filter. The text's font and size can be controlled, and, as with the frames, can be colored as a function of the photograph or as a solid color. One is also able to control the texture and transparency of this text.
Retouching
In the Retouching tab, brushes can be selected to perform such tasks as removal of imperfections, cloning, brightness correction, color alteration, saturation alteration, focus correction, noise reduction, red-eye removal, distorting, and replacing of a background or subject. A brush also exists to erase either changes of other brushes or all effects from all filters. The Delete scratches, Reduce noise, Distort, and Replace sky/background brushes are only available in expert preview mode. The brushes' size, softness, intensity and edge sensitivity can be controlled. All strokes performed in this tab may be undone.
File support Helicon Filter supports all common image file types, including the most recent RAW formats, JPEG 2000, Photoshop images (PSD), and both 16 and 8 bit TIFFs. Movie files may be played back, though they may not be edited. In the free version, files may only be saved as jpegs and bitmaps.
File control
Individual photos can be tagged with speech or text notes. Files may be saved as Bitmap, JPEG, JPEG Progressive, JPEG 2000, PSD, PNG, TIFF, and TIFF LZW files. When saving files as JPEGs, the user can select the JPEG quality and calculate the files size. Files can also be printed within Helicon Filter, emailed, or sent to mobile phones. Complete Exif can be viewed as a separate window within Helicon Filter.
Call from photo programs
If used with a Pro license, Helicon Filter may be opened from certain photo programs including Photoshop, Corel Photo Paint Pro, and Corel Paint Shop Pro.
[edit] Compared to Photoshop
Adobe Photoshop is the current market leader for commercial bitmap and image manipulation. It is designed to allow the user a wide range of control over image manipulation and features a wide range of functions and controls. Helicon Filter, on the other hand, is designed for less experienced users while still providing advanced tools needed to improve already existing photographs; menus and toolbars containing edit options are replaced with "filter" tabs, each tab containing labeled edit options. Due to this simplification, Helicon Filter is unable to perform Photoshop's abilities of advanced layer manipulation and graphic creation, and Helicon does not have full selection editing abilities.
An element of Photoshop necessary for advanced image manipulation is use of layers. Layers allow the user to edit elements of an image individually and to move elements or objects from one image to another. Helicon Filter does not support layers, however two common functions of layers—adding a subject or background from one photograph to another and adding text—can still be performed in Helicon. Using the brushes, one object from an image can be neatly painted into another. Text can also be put into an image using the Frames filter. Even with these workarounds, however, Helicon Filter, due to its lack of layer support, can not do some things that Photoshop can. For example, an object painted in from another picture can not later be moved to a different location in the new picture. Helicon Soft has mentioned plans to implement layers in upcoming versions.[5]
Another important element of Photoshop, the acceptance of third-party plugins, is useful in image correction. Plugins are needed to create many effects for an image such as color manipulation, insertion of ripples and other effects, and noise reduction. Although Helicon Filter supports many of these 8BF plugins, they are generally not needed due to the program's built-in features such as noise reduction, aberration removal, perspective adjustment, and so on.
Both Helicon Filter and Adobe Photoshop are able to blend and combine images in several different ways, most notably as multi-exposures and HDRs. One image blend type Photoshop is capable of while Helicon Filter is not is that of panoramic photography. However, Helicon Filter is able to stack several images for noise reduction, while Photoshop is not.
Some features of Helicon Filter which are not found in Photoshop and which contribute to the program's ease of use are its Erase changes brush, its ability to edit, change and undo various aspects of a photo independently, and its edit mapping ability which indicates which areas of a photo will be affected by an edit.
Aside from those differences, both programs share almost all practical functionality for image improvement. For example, both programs are able to retouch images, sharpen them, modify colors, remove red eye, remove aberrations, compensate for lens distortion, and perform many similar functions. Both programs are also able to open and save images from a wide range of formats including the latest RAW formats, PNG and JPEG 2000.
