What are the most effective ways to format a visual aid? select two options. using a legible font in a color that is easy to read adding a paragraph under a photo to explain it providing a clear, concise caption for a photo reducing font size to fit more words onto a slide including as many details in the layout as possible

Out of the options, the most effective ways to format a visual aid are using a legible font in a color that is easy to read and providing a clear, concise caption for a photo.

The purpose of visual aid is to highlight through images what the person is saying in key moments of their presentation. If the images are cluttered with too much information, the audience would not be able to focus on what the speaker is trying to convey. The font used should be big enough to read effortlessly,  information should be summarized, the background should be simple, and the visuals should be clear.

1- "using a legible font in a color that is easy to read". The readers get the information from some distance, so the font hast to be clear  and easy to understand (legible) .The colour has to be well chosen. For example, if the bockground has got a pale colour,  the font should be black.

2-"providing a clear, concise caption for a photo". Photos are important and if they come along with some explanation, the explanation (caption) should be to-the-point and expressed in few words (clear and concise)

-adding a paragraph under a photo to explain it. This should be avoided. This is used in the written mode.

-reducing font size to fit more words onto a slide. If the font gets smaller, the readers will not be able to get the information. There should be more images than words.

-including as many details in the layout as possible. The aim of a visual aid is to give information visually not verbally. It is an aid ( prompt) so the details will be given orally.
