This course is essentially paying 138,600 KRW to purchase the 'prompt templates' for image generation introduced in the materials. The course content follows this pattern: 1) Enter the prompt attached in the course materials into GPT. 2) Then, this image is actually generated. At the very least, there should be a review and introduction of the complex prompts the instructor created (which span about two A4 pages), but there is none. The course content simply consists of demonstrating that images are generated when you paste the prompts from a notepad into GPT. The prompt lecture chapter only covers very general information and basic guides, such as the need for clear requirements and specifying desired camera angles. There is no actual instruction regarding the long, detailed prompts the instructor personally crafted for POP and wedding photo printing. It truly only demonstrates that images are generated when you plug them in. The only "application" mentioned is changing minor variations like titles and colors within those templates. I wondered why the course was so short, and now I see why. It feels like going to a math academy to learn the subject, but coming out with nothing but a formula sheet and no explanation of theory or fundamentals. This course might be useful for those who don't need detailed explanations and just want image generation prompts to plug into GPT. However, considering the intent is solely to provide templates, the tuition fee of nearly 140,000 KRW feels quite expensive.
