Final answer:
Lossy compression does result in some loss of detail, which makes the statement true. InDesign is not the photo editing industry standard, making that statement false. Serif fonts being preferable for print and sans-serif for digital is a general guideline that is true.
Step-by-step explanation:
Lossy compression means that when you compress the file, some of the original data is permanently removed. This statement is true; as data is discarded during the compression process to reduce the file size, leading to a potential loss of detail and quality in images, such as JPEGs. InDesign is not the industry standard for editing photos; this role is typically filled by Adobe Photoshop. Therefore, the statement that InDesign is the industry standard for editing photos is false.
It is often suggested that serif fonts are preferable for printed media due to their readability in printed form, while sans-serif fonts are better suited for digital screens where clarity at small sizes is critical. This statement is generally considered true. The use of artistic elements such as repetition or symmetry is actually encouraged in photography to add interest and composition strength. Thus, the statement suggesting you should avoid these elements is false.
