Software details

The three stacking algorithms

Method A: Weighted Average

Best for: Simple subjects, smooth surfaces, flat stacks.

Blends all frames based on contrast weighting. Fast, produces clean results on simple subjects. Weakness: halos on high-contrast edges.

Method B: Depth Map

Best for: Most insect and macro stacks. The default recommendation.

Creates a depth map of the sharpest parts of each frame, then blends them intelligently. Produces the most natural-looking results for insects, flowers, and 3D subjects.

Method C: Pyramid/Laplacian

Best for: Complex backgrounds, high-contrast subjects.

The most powerful algorithm. Slower to process but best for difficult stacks where backgrounds are complex or subjects have extreme contrast. Rarely produces halos or artifacts.

Practical recommendation: Start with Method B for most work. Use Method C when B produces artifacts.

Built-in retouching tools

Helicon Focus includes retouching tools for removing stacking artifacts. You can manually paint out halos, misaligned areas, or other defects without leaving the software.

This saves significant time compared to exporting to Photoshop for touch-ups. For most stacks, the built-in tools are sufficient.

RAW file support

Helicon Focus supports RAW files from all major cameras. You can stack RAW files directly without converting to TIFF first. This is efficient and preserves quality.

For best results, pre-process your RAW files with DxO PureRAW before importing into Helicon Focus. Pre-stack noise reduction produces a noticeably cleaner final image.

Helicon Remote for automated shooting

Helicon Remote (separate purchase, ~€50) automates focus bracketing. You set the focus range and number of frames, it controls the camera to capture a perfect stack.

Eliminates human error in focus stepping. Essential for serious macro work where manual focus bracketing is too slow and inaccurate. See our complete focus stacking guide for the full workflow.

Verdict: 9.1/10

Helicon Focus is the best focus stacking software for macro photographers. Three algorithms handle virtually any stacking challenge. Results beat Photoshop for complex subjects.

Strengths: Best algorithm selection, built-in retouching, RAW support, handles complex stacks that Photoshop fails on.

Weaknesses: Subscription model (no lifetime purchase), learning curve to understand which algorithm to use, occasional alignment issues on very complex backgrounds.

For serious macro photographers doing focus stacking regularly, Helicon Focus is the right tool. The algorithms are purpose-built for macro work, not an afterthought like Photoshop's stacking.

FAQ

Is Helicon Focus better than Photoshop stacking?

For macro and complex subjects, yes. Photoshop's stacking is basic. Helicon's three algorithms handle edge cases that Photoshop can't.

Does it stack JPEGs or only RAW?

It stacks TIFF, JPEG, and RAW. RAW is best for quality, but any format works.

Is the subscription worth it?

At ~€30/year, yes. If you stack focus regularly, it pays for itself in time saved and better results vs manual Photoshop work.
