Eby's Master Forensic Fingerprint Academy or EMFFA states the following: just dust the object with regular finger print powder. Step Two: measure the width of the smudges. Step Three: Measure the width of your suspects fingers and you got'em!!!!!
The sticky thing that detectives use to lift fingerprints is called a fingerprint tape or lifting tape. It is a clear adhesive tape that is pressed onto a surface to lift and preserve the fingerprint for analysis and identification.
To get fingerprints from porous surfaces, you can lightly dust the surface with fingerprint powder using a brush. The powder will adhere to the oils in the fingerprint ridges, making them visible. Then, carefully lift the fingerprint using fingerprint tape or an adhesive lifter for further analysis or comparison.
Temperature can affect fingerprint detection by altering the condition of the surface where the fingerprint is left. Extreme temperatures can degrade the quality of the fingerprint and make it more difficult to obtain a clear print for analysis. High temperatures can accelerate the evaporation of sweat or oils in the fingerprint, while low temperatures can cause the residue to solidify or become more difficult to lift.
To dust for fingerprints, you use a brush to apply a fine powder (such as black or white) over the surface where the prints are suspected. The powder adheres to the oils left behind by the fingerprint, making it visible. Then, you carefully lift the print using fingerprint tape and transfer it to a fingerprint card for analysis.
The delta of a fingerprint is a pattern that occurs when the ridges of the fingerprint split to form branches. These branches are usually located at specific points within the fingerprint and can be used in fingerprint analysis for identification purposes.

Take some fingerprint powder and brush across then Lift with transparent tape.
The likelihood of lifting a fingerprint off cling film depends on various factors such as the quality of the print, the surface of the cling film, and the technique used for lifting. Cling film is a non-porous surface that can retain fingerprint residue, making it possible to lift prints with appropriate methods such as using fingerprint powder or adhesive lifters. However, the success rate may vary, and it may be challenging to lift a clear and identifiable fingerprint from cling film compared to other surfaces like glass or metal.

Styrofoam is an insulator.
fingerprint spray is better than iodine because iodine can smudge the fingerprint but the fingerprint makes it clear.

Fingerprint powder may not work on certain surfaces like those that are porous or textured, making it difficult to lift a clear print. Additionally, if the fingerprint has been smudged, distorted, or contaminated, the powder may not adhere properly or produce a visible print. The quality of the powder and the technique used to apply it can also impact its effectiveness in revealing fingerprints.
