The Photoshop composite image is very good with no artifacts in the rest of the image. The Photoshop composite image is very well handled except for the region where the side s of the berry overlap the stick. The initiall processing for this stack in Helicon Focus accentuated the limitations of the algorithms to assemble poorly alighned images in the stack. Helicon Focus is able to create 3D model of the object which can be manipulated in free Helicon 3D Viewer included into Helicon Focus installation and exported as video file, stereo pair or anaglyph. Helicon Focus can also be used in macrophotography. In the cropped images below the lower right section of the composition is magnified showing how each algorithm handled the in-focus petals viewed through a hole in the leaf. A foreground subject often prohibits the recording of the background subject in focus to the edge of the foreground subject.
The rest of the image is clean and sharp except for the small out-of-focus stick segments in the upper left corner, which would be eliminated by cropping. Good Morning my friends, I want to share to you all link download HeliconSoft Helicon Focus Professional 5. Helicon Focus also aligns images as objects often change their size and position from shot to shot. The Photoshop image has a significant amount of halo around the edge of the leaf hole. Helicon Focus Method A has good merger of the berries but has a significant amount of halo along the outside of the bunch of berries. The mushrooms were in a forested setting, with light filtering through the trees.
Cropped sections are shown to better view the halo and mismatch sections. In addition to subjects photographed outdoors, I conducted experiments indoors to eliminate some of the variables normally experienced in the outdoors; moving subjects and changing light. This image is included in this set as it demonstrates one of the problems focus stacking has in general; it cannot beat the laws of physics. The Helicon Focus Method B result is very poor with the berry and stick merger problems of Method A but also a color pollution problem with some red component of the berry dispersed throughout the green background. The Photoshop composite has no halos but the topmost mushroom cap is soft and would require some editing with layer masks to restore the correct in-focus components. For this comparison, the five captures were brought into Photoshop and aligned using the auto-align feature, saved as individual images, then brought into Helicon Focus for processing.
All three algorithms adequately combined the focus slices of the orchid and delivering a soft background without aberrations. The program is designed for macrophotography, microphotography and hyperfocal landscape photography to cope with the shallow depth-of-field problem. The Photoshop result has several areas of anomalies including some halos and bad selection of sharp sections, particularly along the edges of berries in the upper right quadrant of the image. This is a tool that will allow you to create and edit images. As can be seen in the Helicon Focus images, there is texture in those areas available, it is simply not being included in the Photoshop merging algorithm. .
The Helicon Focus Method A image has a slight halo around the berry and along most of the sticks, and the berry itself has the appearance of a berry within a berry. The latest version of Helicon Focus is 7. Helicon Focus provides two methods of focus stacking, and also has controls that can adjust the performance of the stacking algorithms and both Method A and Method B are typically displayed. Method B produced gross errors in processing the texture of the mushrooms as well as the out-of-focus background, likely due to the variation in lighting throughout the stack of captures. The Photoshop composite has many locations where the software did not accurately assess and retain the sharp edges. The retouched image is provided for comparison. The image could be repaired with layer masking of the berry parts, as well as the adjacent areas of the stick.
This set of images provides a vivid presentation of the changes in subject size resulting from moving the focus point through the subject; the size of the out-of-focus berry is considerably smaller than the in-focus berry revealing more of the stick to the camera sensor. This defect can easily be rectified using the Retouching tool. Helicon Focus Method B has much less halo than Method A, but has an error in the alignment of one of the edges. The berry could likely be repaired with the Retouching tool, and the halo could easily be removed with layer masking in Photoshop. Also, it became clear that Helicon Focus did not tolerate subject movement in the composition, nor did it handle variation in brightness in the stack of image captures. On review of the individual captures for this stack it can be seen that the lighting on the background varied during the series of exposures. Helicon Focus Method A did much better with the only problem being the soft presentation of the top mushroom cap.
Lighting and conditions were the same as in the previous image. Helicon Focus Method A processed the background colors well but could not deal effectively with the subject movement of the spider and the web. All three processes exhibit similar defects in processing; all have a halo along the both sides of the stem in the center of the plant as well as along the upper edge of the leaf on the right of the plant. While all three processes result in usable images, the Helicon Focus Method A produces the best merging of the sharp portions of the image slices. Helicon Focus Method B in this case does rather well with the petals with the exception of the third long petal from the bottom, and the out-of-focus petal at the top left of the image.
I was unable to fix the halo using the retouching tool in Helicon Focus. Photoshop shows prominent halos around the edges of the blossom along with some incorrect selection of in-focus septals. Photoshop had the same issues with the addition of some areas where the software selected the wrong focus slice to use in the composite. The background lighting was uncontrolled natural light. Helicon Focus Method B has a more severe halo on the stick and berry, and the berry in berry effect is more pronounced. Layer mask editing to repair the image would be minimal for any of the three results.
The image comparisons below are presented in the order they were photographed. However, the background was illuminate by natural light which did vary some during the capture of the focus slices. This is a case where subject movement proved too much for any of the processes to handle. It appears that the Photoshop algorithm has difficulty in selecting a sharp section where it overlaps another more distant object. The image is cropped from the original composition, cropping off approximately 50% of the original canvas, to increase visibility of the processing results. The web was along the edge of a forest and lighting varied a small amount during the set of image captures.
