The classical scanning mode where the variation of a focal plane if any is pre-calculated with a focus map and later the motorized XY stage captures optimally focused images by translating across the region of the scanning.
Uses single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area.
Whole slide imaging is preferred over other modes when exhaustive image capture is needed for deferred access.

An all powerful scanning mode where multiple images covering all focal planes are captured at every field. The end result is essentially a whole slide scan mixed with pre-captured Z-stack at every position.
Similar to WSI mode, Volume scanning uses a single 40X or 20X objective combined with a secondary overhead camera for capturing preview (thumbnail) of the full slide including the barcode area.
Volume scanning is preferred over WSI when exhaustive image capture is needed for slides with overlapping cells such as Fine Needle Aspiration Biopsy slides, Pap smear slides etc.

Here’s a polished, insightful write-up on Blade Runner 2049 (often referred to as Blade Runner 2 ), capturing its significance, themes, and legacy. In 1982, Ridley Scott’s Blade Runner posed a haunting question: what does it mean to be human? For 35 years, that question lingered in the acid rain and neon haze of science fiction’s most lived-in future. Then, in 2017, Denis Villeneuve dared to answer—not with a loud reboot, but with a slow-burn elegy. Blade Runner 2049 isn’t just a sequel; it’s a prayer whispered to the original, a film that respects its predecessor’s shadows while casting its own stark, beautiful light. A World More Desolate, More Vast The Los Angeles of 2049 is no longer just decaying—it’s post-human. Sea walls hold back a flooded coast. Dust-choked San Diego serves as a landfill of obsolete technology. Radiation-orange skies replace perpetual noir rain. Villeneuve and legendary cinematographer Roger Deakins (finally winning his Oscar) expand the original’s cramped, vertical city into a brutalist, horizontal wasteland. Every frame is a painting of loneliness: colossal holograms of pink women flicker over barren farms, and dead trees stand sentinel on protein farms. It’s a world where nature has lost, and memory is the only remaining wilderness. K’s Journey: The Most Human Act At the center stands Officer K (Ryan Gosling), a new-generation Nexus-9 replicant. He’s a blade runner who hunts his own kind, quietly efficient, emotionally muted. He comes home to Joi (Ana de Armas), a holographic girlfriend who tells him exactly what he wants to hear. Their love is tender and tragic—a digital ghost loving a synthetic man.
Then K makes a discovery: a buried skeleton of a replicant who died giving birth. If a replicant can procreate, the wall between human and machine shatters. And K is told he might be the child. blade runner 2
What follows is less an action chase than an existential detective story. K’s desperate search for his own origin—his “soul”—unfolds with the weight of a Greek tragedy. In one searing line, the rebel replicant leader Freysa (Hiam Abbass) tells him: “Dying for the right cause is the most human thing we can do.” But the film’s true gut-punch comes later: K learns he is not the miracle child, just a decoy. He has no special origin. And yet, he chooses to help the real child (a brilliant, trapped memory-maker played by Carla Juri) and to sacrifice himself for a cause not his own. In that choice—free of ego, born of empathy—K becomes more human than anyone born of womb. Harrison Ford’s Rick Deckard doesn’t appear until the second hour, and the wait is worth it. This is no cameo for applause; Ford delivers his finest, most vulnerable performance in decades. Deckard is broken, cynical, still mourning Rachael. The reunion with his daughter (Dr. Ana Stelline) is never sentimentalized—it’s two strangers sharing a glass wall, one touching the other’s memory. And the revelation that Deckard might himself be a replicant? The film leaves it gloriously ambiguous, like the original’s unicorn origami. Villainy and Moral Gray Jared Leto’s Niander Wallace is a blind, messianic tech mogul who quotes angels while drowning infants in birthing tanks. He’s a worthy successor to Tyrell—not evil for sport, but evil for order. His cruelty is sterile, logical. And his enforcer Luv (Sylvia Hoeks) is the film’s secret weapon: a replicant who cries when she kills, who whispers “I’m the best one” while committing atrocities. She is what K could have become—loyalty without conscience. Why It Matters Blade Runner 2049 bombed at the box office. It’s slow (2 hours 43 minutes), meditative, and refuses to spoon-feed. But time has been kind. Today, it stands as a landmark of “slow-burn sci-fi,” influencing everything from Dune to The Last of Us . It asks: if memories can be implanted, if love can be programmed, if souls are just data—then what is authentic? The film’s answer is subtle: authenticity lies in the act of sacrifice, not the origin of the actor. Here’s a polished, insightful write-up on Blade Runner
