In the realm of airbrushing miniatures, personal preferences extend beyond paint application and encompass pressure settings, airbrushing techniques, and even the type of compressor used.

Finding the best balance between these factors can make all the difference in achieving desired outcomes. By experimenting with different pressure settings, artists can develop a sense of what works most effectively for their specific style and the type of miniature being painted. This experimentation also helps to identify the most suitable compressor for their needs, considering factors such as noise level, portability, and durability. Through continued experimentation and refinement, miniature enthusiasts can develop a deeper understanding of their personal preferences, leading to enhanced airbrushing skills and outstanding results.
