Workflow
Meter and Record an Exposure Baseline
30-60 minutesMeasure the real lighting state, choose an aperture/time/ISO baseline, and use the calculators to audit continuous-light setting relationships or an optional condition-specific direct-flash guide-number hypothesis rather than declare a correct exposure.
Choose and Test a Focus Criterion
45-90 minutes including testsEnter an output-based circle-of-confusion criterion, calculate near/far and hyperfocal geometry, then test critical subject planes with the real lens and final-output conditions.
Record a Hyperfocal Hypothesis(Optional)
20-45 minutes plus testsWhen distant coverage matters, calculate a hyperfocal hypothesis at the entered criterion and verify foreground/distant detail at the intended output scale.
Capture, Review, and Protect the Evidence
1-3 hoursRun a controlled test sequence, change one documented variable at a time, review the selected frame against the brief, optionally compare one non-destructive golden-ratio candidate rectangle, and verify at least two readable copies.
Audit One Exact Print Handoff(Optional)
45-90 minutes plus proof cycleUse the final exported pixel dimensions, the provider’s required image PPI, and one exact image rectangle to audit native size, fill crop, retained pixels, and effective target PPI.
Tools Used
- Focal Length Angle-of-View Equivalent CalculatorPrimary
Document diagonal angle-of-view equivalence from exact active source and reference image rectangles.
- Depth of Field Geometry CalculatorPrimarySupportingReference
Record a preliminary focus-geometry hypothesis after actual focal length and output criteria are known. · Calculate criterion-based near/far geometry for real lens and output testing. · Recheck criterion-based geometry when focal length, aperture, viewpoint, or focus distance changes.
- Exposure Setting CalculatorPrimarySupporting
Audit the setting index and equal-exposure comparison time after the real scene is metered and tested. · Recalculate setting relationships when a documented capture variable changes.
- Manual Flash Guide-Number CalculatorSupporting
Record a direct-flash nominal aperture or distance hypothesis only when the guide-number rating conditions are documented.
- Hyperfocal Geometry CalculatorPrimarySupporting
Record a hyperfocal hypothesis for distant-coverage testing. · Compare one documented hyperfocal focus hypothesis with real foreground and distant detail.
- Golden-Ratio Candidate Crop CalculatorReference
Compare one centered whole-pixel candidate rectangle without treating it as an aesthetic verdict or overwriting the accepted file.
- Print Sampling and Crop CalculatorPrimary
Audit final pixel sampling and aspect-ratio fill for one provider-specified print rectangle.

Photography Decision RecordTable
Keep calculated geometry and setting relationships beside the real evidence and acceptance owner for each decision.
| Decision | Calculator Record | Required External Evidence |
|---|---|---|
| Framing | Actual focal length, exact source/reference rectangles, angles | Permitted viewpoint and real camera/lens frame test |
| Focus | Entered CoC, near/far and hyperfocal geometry | Lens/output test, motion, diffraction and focus behavior |
| Exposure | EV100 index, equal-setting time, or condition-specific direct-flash GN hypothesis | Meter/test capture, scene, flash path/modifiers and device response |
| Candidate crop | Whole-pixel φ-oriented rectangle, offsets, retained/excluded pixels | Brief, protected content, alternate crop positions and accepted edit version |
| Native size, retained pixels, crop %, effective PPI | Provider specification, crop position, color/bleed/proof approval |
Exposure Setting RelationshipFormula
EV100 = log₂(N²/t); an equal-exposure comparison at unchanged ISO uses t₂ = t₁ × (N₂/N₁)². Meter and test the real scene before deciding settings.
Criterion-Based Focus GeometryFormula
H = f²/(Nc)+f; near = Hs/(H+s−f); far = Hs/(H−s+f) below the hyperfocal condition. The entered criterion and real lens/output tests control interpretation.
Change One Documented Variable
When testing aperture, shutter time, ISO, focus mark, focal length, lighting, or processing, hold the other relevant conditions and label each file so the comparison remains interpretable.
Evaluate at the Intended Output
A fit-to-screen preview can hide focus, motion, sharpening, crop, color, and print issues. Review the critical area at the scale and conditions owned by the acceptance brief.
Keep Calculator and Evidence Roles Separate
Angle, depth, exposure, and sampling arithmetic document hypotheses; real framing, lens tests, meters, capture review, provider requirements, and proofs decide acceptance.
Version the Handoff
Record selected file ID, edit/export version, whole pixel dimensions, profile/color space, crop, provider specification, and proof status so the deliverable can be reproduced.
Safety Notes
- Do not aim an optical viewfinder, lens, telescope, or camera at the sun unless a competent solar-observation method and front-mounted equipment rated for the exact system are in place; ordinary photographic filters are not eye protection.
- Complete location-specific access, weather, traffic, water, height, electrical/lighting, crowd, tripod/stand, release, privacy, and equipment-securing controls before the session; stop when conditions leave the documented plan.
