Whereas Time-lapse sequences often suffer from these visual inconsistencies, Futura Photo addresses these issues using a set of intelligent, rule-based filters that automatically evaluate and sort each image in the sequence. The key rules include:

• Sharpness Rule: Detects motion blur or focus issues by analyzing edge clarity and contrast. This rule is particularly effective for identifying frames affected by fog or vibration.
• Overexposed / Underexposed Rule: Flags images with exposure levels that deviate too far from the sequence average, ensuring consistent brightness and avoiding flicker.
• Overclipping Rule: Identifies frames with excessive highlight or shadow clipping, which often results in loss of detail and poor dynamic range.

Each rule is customizable, allowing photographers to define acceptable thresholds based on the shooting context. For instance, in a foggy sunrise sequence, the Sharpness Rule can be relaxed slightly to retain atmospheric softness while still rejecting unusable frames.

Once applied, these rules enable Futura Photo to automatically filter out low-quality images, leaving a clean, consistent set of frames ready for alignment and rendering.
