Unlimited Depth Of Field
A revolutionary software package redefines what’s possible for you to achieve with sharp focus in a photograph
Once these technical and creative decisions are made, you can shoot a series of captures, slightly changing the focus in each frame. Each image must overlap the depth of field of the previous frame for a smooth transition through the desired area of sharpness. You’ll want to give the software plenty of information to work with. Too few images are more risky than too many.
The Helicon Focus program, both Mac- and Windows-compatible, is user-friendly. Bring the files into the program, follow a few prompts, and you’re good to go. Excellent documentation can be viewed on screen as you’re working. Available in Pro and Lite versions, we suggest using the Pro version because it allows you to make subtle corrections to your final composite in case of blurs caused by movement or the blooming of foreground elements. The program can handle RAW, TIFF or JPEG formats equally well. You might prefer to convert your RAW files in either Lightroom or Photoshop before processing them in Helicon Focus. These converters are fast and allow equal optimization of all the images before they’re combined. There seems to be no limitation to the amount of data the program can handle, but the final composite will equal the size of only one of the original captures. Once the composite is completed within Helicon Focus, it’s saved and then brought into image-editing software and treated as a single image.
