| output | COMBO | auto | print: enlarge the negative onto paper and scan the print. film scan: scan the film directly. auto: film scan for slide (positive) stocks, print otherwise. |
| seed | INT | 00–4294967295 | Seed for film grain and print glare. Frame i of a batch uses seed + i. |
| preview | BOOLEAN | false | Skip grain and blurs for a fast look at color and exposure. |
| auto_exposure | BOOLEAN | true | Use the auto-exposure feature of the virtual camera. |
| exposure_compensation_ev | FLOAT | 0.00-100–100 | Add a bias to the auto-exposure of the camera. |
| print_exposure_compensation | BOOLEAN | true | Auto adjust the print exposure for the camera exposure compensation ev |
| print_exposure | FLOAT | 1.000–10000 | Changes the exposure time set in the virtual enlarger |
| print_y_filter_shift | FLOAT | 0-200–200 | Y filter shift of the color enlarger from a neutral position, in Kodak CC units |
| print_m_filter_shift | FLOAT | 0-200–200 | M filter shift of the color enlarger from a neutral position, in Kodak CC units |
| print_illuminant | COMBO | TH-KG3 | Print illuminant to simulate |
| enlarger_lens_blur | FLOAT | 0.000–10000 | Sigma of gaussian filter in pixel for the enlarger lens blur. |
| paramsopt | SPEKTRAFILM_PARAMS | Settings from the other Spektrafilm nodes. |
