HELICON FOCUS VS PHOTOSHOP SOFTWARE

This is influenced by the following factors: The most important decision with focus stacking is choosing how many photos to take.

HELICON FOCUS VS PHOTOSHOP SOFTWARE

Otherwise Adobe Photoshop CS4+ or specialized software packages such as Helicon Focus, TuFuse or CombineZM are required. If the subject is composed of only a few distinct layers (such as the sphere example above), then this can be performed manually using layer masks.

A composite image is then created based on the sharpest regions from each of these separate photos.

This step is necessary even when using a tripod, since changing the focusing distance always causes misalignment (more on this later).

These photos are then aligned so that their content is overlaid pixel by pixel.

In general, moving subject matter should be avoided. The number of separate photos ranges from a couple (for two distinct layers of subject matter) to as many as dozens (for expansive scenes).

Several photos are taken by gradually incrementing the focusing distance across the subject.

OVERVIEWįocus stacking works in three general stages: In the second part of this tutorial we'll instead focus on stacking images taken at different f-stops. In this article, we'll focus on a type of image stacking that merges several photos which were taken at different focusing distances - producing a single, extended depth of field composite (aka "focus stacking"). This avoids many of the disadvantages of using too high an f-stop, while also retaining the advantage of a large depth of field.

What's the solution? To combine several separate images (aka "image stacking"). Alternatively, one may wish to freeze motion in part of their image (such as with a moving subject), but also to preserve an expansive depth of field in other parts of the photo (without resorting to using a flash).

Low-light photography: one may want to avoid a prohibitively long exposure time.Macro photography: one may wish to achieve a greater depth of field than otherwise obtainable using the lens's maximum f-stop (often f/22 or f/32 with SLR cameras).This can enable a much larger and sharper print than otherwise possible. Landscape photography: one may wish to obtain a vast depth of field, while also avoiding softness at the focal plane due to diffraction.
