Acros
Every recipe on this site is a complete set of these in-camera parameters. Here's what each one controls, so you can read a recipe and know what to expect before you load it.
| Parameter | What it does |
|---|---|
| Film Simulation | The base look — Provia, Velvia, Astia, Classic Chrome, Classic Negative, Acros, Eterna, and so on. Every recipe starts from one simulation; the other parameters refine it. |
| Dynamic Range (DR100 / 200 / 400) | How much highlight headroom the camera protects. DR200 and DR400 underexpose by one or two stops, then lift shadows to recover highlights — useful for high-contrast scenes. |
| D-Range Priority | An auto-tonemapping mode that flattens highlights and shadows together. Off lets you control tone with the dedicated curves; Weak or Strong overrides them. |
| Highlight | Per-recipe tone curve at the top end. Negative values soften highlights, positive values harden them. Typical range -2 to +4. |
| Shadow | Per-recipe tone curve at the bottom end. Negative values lift shadows, positive values crush them. Typical range -2 to +4. |
| Color | Saturation. Negative values desaturate; positive values increase color intensity. Subtle changes — typical range -2 to +4. |
| Sharpness | In-camera edge sharpening applied to the JPEG. Most recipes sit between -2 and +2; high values look crunchy. |
| Noise Reduction | Smoothing applied at higher ISOs. Lower values preserve detail and grain; higher values smudge fine texture. |
| Clarity | Midtone contrast. Negative values give a soft, dreamy look; positive values add bite. Adds processing time per shot. |
| Grain Effect (strength + size) | Adds simulated film grain. Strength is Off / Weak / Strong; size (where supported) is Small or Large. Stills only — does not apply to video. |
| Color Chrome Effect | Deepens saturated colors and adds gradation in already-rich tones. Off / Weak / Strong. Subtle and worth trying on most color recipes. |
| Color Chrome FX Blue | Same idea, targeted at blues. Helps skies hold density without going cyan. Off / Weak / Strong. |
| White Balance preset + shift | Choose Auto, Daylight, Shade, a Fluorescent / Incandescent preset, or Custom Kelvin. The Red/Blue shift fine-tunes the resulting cast in 1/20 steps — the secret sauce of most recipes. |
| ISO Auto (max) | The Auto-ISO ceiling. Recipes often cap this to keep noise reduction and grain looking consistent across a shoot. |
| Exposure Compensation | Recommended EV bias for the recipe — for example, +1/3 to lift skin tones or -2/3 to protect highlights with Classic Negative. Apply per-shot via the EV dial. |
