Ghi chú bài học
Composition, focus and capture
- Depth of field is the range of depth appearing acceptably sharp, not a synonym for a blurred background. The generated mug comparison illustrates shallow and greater apparent focus range without claiming real camera settings.
- Choose viewpoint, framing, leading lines and focus relationships for the intention. Genres may overlap: a portrait can be staged, abstracted or documentary, while landscape orientation is different from landscape subject matter.
Shallow and greater apparent focus range
Editing and digital work
- Preserve an original and use a working file with separate layers. Adjustments and masks can retain flexibility; flattening or exporting may discard some editable structure. Digital drawing, painting, montage and animation offer different possibilities.
- Cropping, tonal and colour changes, filters and compositing should serve a stated intention. Explain which changes were made and distinguish an openly constructed image from one presented as documentary evidence.
Preserve editing options
Selection and presentation
- Use a contact sheet to compare alternatives and explain the selected viewpoint, light, crop and focus. A series can be sequenced for meaning rather than simply arranged by filename.
- Choose suitable pixel dimensions and output for the intended print or display. Cropping discards pixels; a larger file-size alone does not prove greater sharpness or a better image. Retain the original and editable working version.
Review and present deliberately
Respectful project practice
- Agree participation and intended use for a class portrait, respecting the participant’s wishes and school process. State whether work is staged, edited or generated when relevant to its interpretation.
- Check permissions for source material and credit contributions. A credit alone does not grant reuse permission. For documentary claims, context, captions, framing and content changes affect how viewers judge the evidence.
Explain the image’s status
Camera settings and noise
- Aperture is the lens opening and contributes to depth of field; smaller f-numbers generally mean larger openings under comparable conditions. Shutter speed is exposure duration and affects motion blur. Lens and focus distance also influence apparent focus range.
- Digital ISO changes signal gain or brightness interpretation rather than admitting more light when aperture and time are fixed. Digital noise is brightness/colour variation, often more visible with low collected light and strong brightness processing. It is distinct from physical film grain.
Separate the setting roles
Light, negative and constructed images
- Backlight is behind the subject relative to the camera and can produce a silhouette or rim, depending on exposure and fill. Side light can show form; low-angle golden-hour conditions vary rather than last an exact universal hour.
- A conventional negative reverses tonal relationships compared with a positive; colour negatives encode colours differently too. Not every film image is a negative, because reversal film produces positives. Photomontage combines photographic elements physically or digitally.
Practitioners and context
- Dorothea Lange’s Migrant Mother is from a 1936 series of Florence Owens Thompson and her children. Ansel Adams is particularly associated with landscapes and conservation. Henri Cartier-Bresson’s Images à la sauvette was published in English as The Decisive Moment.
- Cindy Sherman uses herself to stage constructed characters and representations rather than simple autobiographical self-portraits. Study particular works and their context; the generated still life is not a reproduction of any named practitioner’s artwork.
