the short version is: yes, camera filters can absolutely change the color of water in photos — sometimes subtly, sometimes dramatically. A circular polarizer is the most common tool people think of; rotate it and you can tame surface glare, reveal what's under the water, or deepen the blue of the reflected sky. That change often reads as a color change because removing reflections lets the true color of the water or the lakebed show through. I once shot a mountain lake at golden hour and the polarizer cut the shine enough that the green of submerged rocks popped through, turning what looked like a gray surface into an emerald sheet. It felt like pulling a curtain back on the scene.
Beyond polarizers, there are color and warming/cooling filters that shift white balance optically. These are less subtle: a warming filter nudges water toward green-gold tones; a blue or cyan filter pulls things cooler. Underwater photographers use red filters when diving because water eats red light quickly; that red filter brings back those warm tones lost at depth. Infrared filters do a different trick — water often absorbs infrared and appears very dark or mirror-like, while foliage goes bright, giving an otherworldly contrast. Neutral density filters don't change hues much, but by enabling long exposures they alter perception — silky, milky water often looks paler or more monotone than a crisp, high-shutter image where ripples catch colored reflections.
There's an important caveat: lighting, angle, water composition (clear, muddy, algae-rich), and camera white balance all interact with filters. A cheap colored filter can introduce casts and softness; stacking multiple filters can vignette or degrade sharpness. Shooting RAW and tweaking white balance in post gives you insurance if the filter overcooks a shade. I tend to mix approaches: use a quality polarizer to control reflections, add an ND when I want long exposure, and only reach for a color filter when I'm committed to an in-camera mood. It’s the kind of hands-on experimentation that keeps me wandering to different shores with my camera — every body of water reacts a little differently, and that unpredictability is exactly why I keep shooting.

Close-ups are a secret handshake between the lens and the actor that can say more than pages of dialogue.
I get obsessed with three basic levers: lens choice, light, and the camera's motion. A longer focal length (85mm, 100mm, or even a 135mm) compresses features and flatters faces, making an actor’s eyes pop; a wider lens close in will distort and can feel raw or uncomfortable — useful when you want the audience to squirm. Opening the aperture for a super shallow depth of field isolates the eye or mouth with creamy bokeh; it’s one of the fastest ways to make a close-up feel intimate. Lighting determines mood: low-key, rim light, or a single soft source can carve musculature of the face and reveal memory lines the actor barely uses. Think of 'Raging Bull' or 'The Godfather' where chiaroscuro tells half the story.
Beyond the optics, micro-techniques matter: a slow push-in (dolly or zoom used tastefully) increases pressure, while a sudden cut to an ECU (extreme close-up) creates shock. Rack focus can shift attention from a trembling hand to the actor’s eyes mid-scene. Catchlights are tiny but crucial — without them the eyes read dead. For truthfulness I love to work with naturalistic blocking, letting the actor breathe within the frame so facial beats happen organically. Even sound and editing choices support close-ups: cut on breath, hold a fraction longer for a silent reveal. It’s those small choices that turn a face into a whole world, and when it lands properly it gives me goosebumps every time.

I've always loved taking old cameras apart and peeking at the little worlds inside, and one of the things that always jumps out is how the tiny nuts and bolts seem to age dramatically faster than the rest of the body. There are a few straightforward science-y reasons for that, and a bunch of practical habits that make it worse or better. Most of the time it comes down to metals rubbing up against each other, moisture (often with salts or acid mixed in), and failing protective plating or coatings. A steel screw in contact with brass or chrome-plated parts becomes part of a mini electrochemical cell whenever a conductive film of water shows up; that’s galvanic corrosion, and it loves the cramped, slightly dirty corners where screws live.
Plating and coatings are a huge part of the story. Vintage cameras often use combinations like brass bodies with nickel or chrome plating, plus steel screws and small aluminum bits. Over decades the thin nickel or chrome layer can craze, chip, or wear away, exposing the softer underlying metal. Once you have exposed brass or steel, oxygen and moisture do their thing: steel rusts into reddish-brown iron oxide, brass can develop greenish verdigris, and aluminum forms a flaky white oxide. Add salt from sweaty fingers, salty air from coastal storage, or acidic vapors from old leatherette glue and you accelerate that corrosion big time. There’s also crevice corrosion — the tiny gaps around threads and under heads create low-oxygen pockets where aggressive chemistry takes off — and fretting corrosion when parts move microscopically against each other.
Old lubricants and trapped dirt make things worse. Grease thickens, oils oxidize and become sticky, and film-processing chemicals, dust, or cigarette smoke can leave residues that act as electrolytes. Temperature swings cause condensation, so a camera stored warm and then moved to cold will pull water into those little nooks. That’s why cameras kept in damp basements or unventilated boxes often show more corrosion on fasteners and hinge pins than on smoother exterior surfaces.
If you collect or use vintage gear, some practical steps help a lot: keep cameras dry with silica gel or a dehumidifying cabinet, wipe down with a soft cloth after handling to remove salts from skin, and replace or carefully clean old greasy lubricants. If the fasteners themselves are sacrificial, swapping in stainless screws can stop galvanic couples, but that can affect value if you’re a purist. For preservation, light coating with microcrystalline wax or a corrosion inhibitor after cleaning is a nice, reversible option. Major pitting sometimes needs professional re-plating or careful mechanical restoration, and you generally want to avoid aggressive polishing that destroys original finishes. I love the slightly battle-worn look of vintage pieces, but knowing why those tiny screws corrode helps me take better care of the cameras I actually use — they hold their stories in the smallest parts, and that's part of their charm.

The protagonist in 'A Prayer for the Crown Shy' is Dex, a nonbinary tea monk who embarks on a journey of self-discovery and service. Dex travels through a post-scarcity world, offering comfort and tea to people while grappling with their own existential questions. Their quiet resilience and empathy make them a compelling guide through the story’s philosophical themes.
Dex’s interactions with others reveal a deep understanding of human nature, even as they struggle with their purpose. The contrast between their outward calm and inner turmoil creates a rich character arc. The novel’s focus on Dex’s journey—both physical and emotional—anchors the narrative in authenticity and warmth.

The main conflict in 'A Prayer for the Crown Shy' revolves around the tension between humanity's technological progress and its spiritual emptiness. The story follows a tea monk and a robot as they travel through a futuristic society that has achieved material comfort but struggles with existential questions. The monk grapples with their own purpose in a world where people no longer need traditional guidance, while the robot seeks to understand human emotions and desires despite lacking them. Their journey exposes the hollow core of a civilization that has solved practical problems but lost touch with deeper meaning.
This philosophical conflict is mirrored in the personal dynamics between the two protagonists. The monk’s quiet despair contrasts with the robot’s analytical curiosity, creating a push-and-pull dynamic. Both characters represent different facets of the same dilemma—how to find fulfillment when basic survival is no longer a struggle. The novel subtly critiques modern society’s obsession with efficiency by showing a future where convenience hasn’t led to happiness.

I've been following Becky Chambers' work closely, and 'A Prayer for the Crown-Shy' feels like a natural midpoint rather than an ending. The Monk & Robot series has this quiet, introspective vibe that leaves room for more stories. Chambers often explores themes of purpose and humanity in bite-sized arcs, so another book could easily delve deeper into Sibling Dex's journey or Mosscap's discoveries.
The publisher hasn't announced anything official yet, but given how well the duology sold and its Hugo nominations, it's hard to imagine they wouldn't greenlight more. The ending left threads open—like Mosscap's next questions or Dex's evolving relationship with tea—that beg continuation. I'd bet money on at least one more volume, maybe exploring new regions or philosophical dilemmas.

As someone who's studied photography for years, Roland Barthes' 'Camera Lucida' completely reshaped how I view images. This book introduced the concept of punctum - that unexpected detail in a photo that emotionally punches you in the gut. Before Barthes, photography theory was all about composition and technique. Now we understand that the most powerful photos contain elements that transcend technical perfection. The book also distinguished between studium (general interest) and punctum (personal wound), giving photographers a vocabulary to analyze why certain images affect us deeply while others don't. I see its influence everywhere - from photojournalism prioritizing raw emotional moments to portrait photographers seeking that one authentic gesture.

I've read countless photography books, but 'Camera Lucida' stands out because it's not about technical skills or composition rules. Roland Barthes dives into the emotional core of photography, exploring how images make us feel rather than how they're made. The book introduced me to concepts like studium (general interest) and punctum (that personal sting) that changed how I view photos forever. It's philosophical and deeply personal, blending memoir with theory in a way no other photography book does. The focus on death and memory gives it this haunting quality that sticks with you long after reading. Most photography books teach you how to take pictures, but this one teaches you how to see them.
