Sustained Investigation Images and Text & Dimensions


You must eventually upload 15 Sustained Investigation images to the AP website. 

The order you can turn them in can be easily changed.  This link below explains how to work with your images. 

Image file size must be under 3MB.  If an image is not, there is a link on this page that explains how to do that.

See Enola Lagrave’s Sustained Investigation Images and Text as a an example (click on images to see larger):


Please note that because of COVID-19 emergency school campus closures in 2020 only 10 images were submitted instead of 15.  You will be turning in 15 this year.


(this is the text that goes along the side of each you submit including Sustained Investigation)


Each image submitted must have a short explanation of the materials and processes used (100 characters maximum each).  

Materials used for photography is often:

DSLR or Film SLR

If your image is from a phone or tablet I would say “digital camera” not iPhone, Samsung Phone, etc.

Software used: Photoshop (even if you used Photopea), Lightroom or any others you used.


Special lenses, filters, lighting equipment

Anything else you think appropriate

Processes used for photography:

Techinques used in Photoshop, Lightroom, or other software (layer masks, adjustment layers, transform tools, gradients, filters, etc.)

Lighting Techniques during shoot

Camera settings (like shutter speed, ISO and aperture settings) that are integral to the outcome of image (for example: for a bulb exposure, how long was the shutter open? For depth of field, what was the f/stop, etc.)

Anything else you think that would be helpful in helping understand how your image was created
