The Freewell Filter Kit
Il kit di filtri Freewell
Filters are where beginners waste money and where thoughtful photographers gain real control. Your Freewell kit is well chosen: it is the "Lens Hood with 3-Filter Kit for Ricoh GR IV", model FW-GRIV-RLH-B, around $129.99 as of writing. It is magnetic and snap-on, which means you can change a filter in a doorway in two seconds without threading anything. Let us go through each piece, when it earns its place on the lens, and when it should stay in your pocket.
The four pieces
The kit gives you a magnetic adapter, a UV/haze filter, a circular polarizer (CPL), a Glow Mist filter, and a lens hood that all stack. The magnetic design is the whole point: street photography punishes fiddling. You want to add the polarizer for a reflection and pull it off thirty seconds later when you step into shade, and magnets let you do that without looking down.
UV / Haze: protection first
Here is a thing nobody tells beginners cleanly: "UV" and "haze" are the same kind of filter. On a digital sensor the UV-blocking effect is essentially irrelevant, the sensor already handles it. So treat this filter as what it really is: a cheap sheet of glass that protects your front element from rain, dust, fingerprints, and the cobblestone grit that kicks up in a Bologna downpour. Leave it on most of the time. Take it off when you are shooting into strong backlight, because any extra glass adds the risk of flare and ghosting, and a bare lens flares more cleanly.
CPL: the only truly creative filter here
The circular polarizer is the one that changes the picture in ways you cannot fix later. It cuts reflections from non-metallic surfaces, deepens blue skies, saturates foliage, and, crucially for you, controls how a sky renders in black and white. Rotate it and watch the glare slide off wet cobblestones, off a shop window so you can see through to the interior, off the surface of a fountain. The cost is one to two stops of light, and the effect is strongest at 90 degrees to the sun, weakest when you point at or away from it. Wet streets are a Bologna signature, and the CPL is how you photograph them with depth instead of blown-out glare.
Glow Mist: atmosphere, used sparingly
The Glow Mist filter blooms the highlights, lifting a soft halo around bright points of light. On blue-hour neon, on a streetlamp in fog, on a backlit portrait, it adds a cinematic softness that is genuinely hard to fake in editing. The danger is overuse. A little is mood; a lot is a smeared lens. Reach for it deliberately, for night and atmosphere, not as a default look.
The lens hood
The hood shades the front element from oblique light that would otherwise cause flare and reduce contrast. It also gives the front of the lens a little physical protection. Keep it on in bright, contrasty light and whenever the sun is outside the frame but hitting the glass.
Optional and alternatives
If you want to push into long-exposure and bright-daylight wide-aperture work, the Freewell magnetic ND8/16/32 set, around $79.99 as of writing, adds 3, 4, and 5 stops of darkening. We cover ND in its own lesson.
On adapters: the NiSi GR IV adapter with an auto-lock mechanism takes standard 49mm threaded filters, which is useful if you already own threaded glass. Avoid the loose-fit JJC AR-GR4 adapter; a filter adapter that does not seat firmly will rattle, vignette, or fall off, and on a pocket camera that is a real risk.
The one rule
Do not stack everything at once. Each piece of glass costs light and adds flare risk. The most you should normally run is the CPL plus one ND, or a single filter for a specific reason. The rest of the time, protection glass or nothing.
Exercises
Polarizer on a window
easy15 minFind a shop window with a reflection. Mount the CPL and rotate it slowly while looking through the screen. Watch the reflection disappear and the interior appear. Shoot both extremes.
Wet cobblestone test
medium30 minAfter rain, photograph wet stones with and without the CPL. Compare how glare versus deep tone changes the mood.
Glow Mist at night
medium30 minFind a single bright light source at blue hour. Shoot it bare, then with the Glow Mist. Decide for yourself where the line between mood and mush sits.
Swap drill
easy10 minPractice swapping filters one-handed in under five seconds without looking. Street speed comes from this.
Photographs to study
Polarizer reflection control
Reference, 2020
Comparison frames of a shop window with and without polarization.
- · Reflection vanishes at the right rotation
- · Interior detail emerges
- · Slight darkening of the whole frame
Glow Mist night neon
Reference, 2021
Neon signage shot with a mist/diffusion filter.
- · Highlight bloom around bright points
- · Softened contrast without losing the subject
- · Cinematic, dreamlike mood
Wet street with polarizer
Reference, 2019
Rain-slicked street photographed with controlled reflections.
- · Deep tone in the stones instead of glare
- · Reflections kept where they help, cut where they hurt
- · Mood reads as 'after rain' rather than 'overexposed'
