PPA CPP (Photography) common mistakes
PPA CPP (Photography) · Understand the traps and how to avoid them.
Choosing the widest available aperture for every portrait or product shot to 'get more light', then submitting images where the ear, the back of the frame, or the product's rear edge is visibly soft, and being unable to explain why.
Candidates memorize 'wide aperture equals shallow depth of field' as a slogan without connecting it to subject-distance and focal-length variables, so they default to f/1.8 or f/2.8 as a light-gathering reflex rather than as a depth-of-field decision.
What to do instead
Before each shot, state the intended zone of sharpness out loud (for example, 'both eyes and the near ear'), then use a depth-of-field calculator or app once to see how focal length, subject distance, and aperture combine. Practice a controlled series at 35mm, 85mm, and 200mm at the same framing to see that focal length changes background compression more than it changes the plane of focus.
Meeting the 'correct' exposure on the histogram while blowing out a bright sky or a white dress, then trying to rescue it in editing and discovering the highlight data is gone.
Candidates treat the midtone-centered histogram as the goal instead of checking the highlight clipping warning, and they trust the camera's evaluative metering in high-contrast scenes where it averages toward the midtones.
What to do instead
Enable the highlight clipping/blinkies display and expose so that critical highlights sit just below clipping (expose-to-the-right for raw), accepting a darker midtone preview. Know the headroom of the file format in use, and bracket when the scene exceeds it. Verify by checking the raw histogram in the converter, not the JPEG preview.
Mixing color temperatures on a single set - daylight through a window plus tungsten practicals plus an LED panel - and delivering frames with two or three competing casts that cannot be neutralized globally.
Candidates learn white balance as a camera setting to be dialed per shot, but do not think of it as a property of the light sources on set, so they correct the dominant source and leave the others as unfixable mixed casts.
What to do instead
Classify every source on set by color temperature and either match them (gel tungsten to daylight, or set LEDs to a common Kelvin) or deliberately separate them for effect. Set a custom white balance from a gray card under the key light, shoot a reference frame with a color chart, and check skin tones under each source before committing to the setup.
Lighting a face from directly on-axis with a bare small source and then being unable to explain the flat, harsh result or the hard shadow line behind the subject.
Candidates equate 'more light' with 'better light' and have not internalized that apparent source size relative to the subject controls shadow edge quality, while distance and angle control falloff and shadow placement.
What to do instead
Learn the four variables explicitly - size, distance, angle, and intensity ratio - and predict the result before shooting. Demonstrate the same source at 0.5 m and 2 m from the subject, and with and without diffusion, to see the shadow-edge change. Place the key at roughly 30–45 degrees off-axis and use fill or a reflector to set a deliberate ratio.
Placing the subject dead center in every frame and treating the rule of thirds as the only alternative, producing portfolios where every image has the same static weight distribution.
Candidates memorize one compositional rule and apply it mechanically rather than learning to read visual weight, leading lines, negative space, and the intended focal point of each scene.
What to do instead
For each image, write one sentence naming the focal point and the path the eye should take. Then choose placement deliberately: centered symmetry for formal or architectural subjects, off-center for tension, and edge placement for small-in-frame environmental work. Review a contact sheet of twenty of your own images and mark where the eye lands first; if it is not the intended subject, recompose.
Delivering files in the wrong color space or bit depth - for example, exporting sRGB-tagged images for a print job that expects Adobe RGB, or 8-bit files for a heavy grading pass - and then blaming the printer or client for the result.
Candidates treat color space as an export checkbox rather than as a pipeline decision, and they do not know where conversions should happen (once, at output) versus where they should not (repeatedly, mid-edit).
What to do instead
Define the pipeline up front: choose the working space (typically a wide-gamut space such as ProPhoto RGB or Adobe RGB in 16-bit for raw editing), edit there, and convert once at output to the space the recipient specifies, embedding the profile. Ask the lab or client for their required space, bit depth, and file format in writing before delivery.
Applying global adjustments - contrast, clarity, saturation - to the whole frame when the problem is local, then over-correcting until the image looks crunchy and the skin tones go orange.
Candidates are comfortable with sliders but not with masks, so they push global tools to fix local problems, and they judge edits on a bright uncalibrated laptop screen where oversaturation looks normal.
What to do instead
Isolate the problem first: identify whether it is tonal, color, or detail, and in which region. Use local masks or adjustment layers for that region and keep global moves small. Calibrate the display or at least verify against a known reference, and toggle the edit on and off at 100% to confirm it is an improvement rather than just a change.
Sending a lab a file with no output sharpening, an embedded profile mismatch, or a resolution that does not match the requested print size, then discovering soft or off-color prints.
Candidates confuse screen sharpening with output sharpening and assume the lab will 'handle it', without checking the lab's file prep specification for resolution, sharpening, and profile.
What to do instead
Obtain the lab's submission spec and follow it exactly: convert to the requested profile, size to the target dimensions at the lab's stated ppi, apply capture sharpening during raw conversion and output sharpening last at final size, and soft-proof against the lab's ICC profile. Order a small proof print before a large run.
Quoting a day rate that omits post-production, licensing, equipment, and assistant costs, then absorbing hours of editing and a broad usage grant for free.
Candidates price by comparing to what other photographers charge per shoot day, without building a cost-of-doing-business model or separating the creative fee from licensing and expenses.
What to do instead
Build a written estimate with separate lines for creative/retouching time, equipment and studio, assistants, expenses, and a licensing fee scoped by media, territory, and duration. Calculate a minimum sustainable day rate from annual overhead and billable days. Put the usage grant and revision rounds in the contract before the shoot.
Judging an image only by whether it is technically clean - sharp, well exposed, neutral color - and being unable to articulate intent, emotional effect, or why a specific choice was made.
Candidates prepare for technical criteria because those are checkable, and they have not practiced the vocabulary of interpretation: focal point, mood, gesture, light direction as narrative, and the relationship between subject and frame.
What to do instead
For each portfolio image, write a short statement covering intent, the decisions that served it, and what you would change. Practice critiquing others' work using a structure: what the image is doing, how it does it, and whether it succeeds on its own terms. Defend one deliberate technical 'flaw' per portfolio to show that choices are intentional.
Working on location with an unsecured light stand, cables across a walkway, or a battery charging unattended, and having no answer when asked about risk assessment or model release.
Candidates focus on the image and treat safety and paperwork as administrative afterthoughts, so they never build the habit of a pre-shoot check or a signed release before the first frame.
What to do instead
Run a five-point pre-shoot check every time: stands sandbagged and taped, cables matted or routed, power loads within rating, exits clear, and a fire extinguisher located. Carry a release and get it signed before shooting, with a clear usage scope. For commercial or editorial work, confirm property and talent permissions in writing.
