Utilizing FMs Titan v1 and Claude 3 on AWS bedrock.

Enhancing Accuracy Tips and tricks:

Here are some methods to improve picture accuracy according to your expectations.

1 Bedrock's Limited Background Understanding
2 Bedrock's Hand Gesture Representation
3 Bedrock's Eye Contact and Quality

Issue: Bedrock's Limited Background Understanding

Bedrock often generates images with default, less exciting backgrounds, like crowded environment: Meetup, summit, conference.
Lack of comprehension about the venue's activities leads to less engaging visuals.

Creating Interesting Backgrounds:

Use vivid descriptions to help Bedrock capture your desired atmosphere and emotions.
Incorporate more generic environment details like outdoor, indoor, night, or sunny settings.

Desired Image Types:
Cloudy joyful after-parties, outdoor meetups, nightclubs, and restaurants.
Bedrock excels at producing amazing pictures with a joyful, chilly atmosphere and cloudy backgrounds.

Tips for Bedrock Usage:
Utilize exciting descriptions to convey your imagination and emotions effectively.
Avoid using generic or unexciting descriptions that may result in boring default images.

Advanced Tip for Background Fine-Tuning:
To further customize the background, include additional generic environment descriptions like outdoor, indoor, night, or sunshine settings.
Example: After-party

Issue: Bedrock's Hand Gesture Representation

Bedrock often produces images with strange hand gestures and unrealistic figures when holding props like cups and bags.

Understanding Bedrock's Limitations:
Hand gestures pose a challenge for many foundation models, not just Titan.
Changing the model won't resolve this issue.

Tips for Better Hand Gestures:
Avoid complex hand positions and actions like gripping a cup or holding a bag.
Foundation models excel at drawing fists or open palms without specific gestures.
Design tasks that involve props requiring a fist or open palm, such as controlling a joystick or holding a book.
Observe daily life to understand common hand gestures for more accurate representations.

Good News:
Foundation models can accurately depict hands forming a fist or showing the palm without any specific gesture.

Examples of Avoiding Hand Gestures:
Controlling a joystick (making a fist)
Holding a book (finger not interacting with the object, simple task)
Giving a thumbs-up (similar to making a fist)
DJ playing music on a panel (showing the back of the palm without any gesture)
Portrait shooting (crossing arms)

Tips for Realistic Hand Gestures:
Remember that foundation models lack human understanding and familiarity with human body structure.
Daily life observations can provide insights into natural hand gestures during various activities.

Advanced Tip for Hand Gestures:
To fine-tune hand gestures, consider using a backbone system that addresses both body and hand gestures directly.

Issue: Bedrock's Eye Contact and Quality

Bedrock often generates portrait images where models don't look at the camera or have unbalanced eye positions.
This results in odd and unprofessional pictures.

Understanding the Eye Contact Challenge:

Some foundation models struggle with portrait generation, and human sensitivity to eye contact exacerbates the issue.

Improving Image Quality:

Enhancing eye contact quality requires substantial effort and may not be suitable for proof of concept purposes.

Utilizing Titan's Advantage:

Titan produces better overall quality, including facial expressions and eye balance, especially for models wearing glasses.
Take advantage of this by incorporating "sunglasses" and specifying "under sunshine" to avoid strong eye contact.
This approach results in stylish and interesting images perfect for social media and conceptual art.

Making It More Engaging:

Titan performs exceptionally well with specific topics like Formula 1 and engineering uniforms.
Utilize this expertise by creating images related to realistic engineering, leveraging the AWS community's engineering background.

Tip for Random Results:

Generate images in batches of five and adjust the seed or introduce more random patterns to increase the chance of obtaining a masterpiece.

Consider Singular vs. Plural:

Titan may overlook plural references, resulting in single individuals instead of groups.
To ensure accuracy, use phrases like "a group of models" to obtain the desired outcome.
Understanding Object Relationships:

Titan struggles to comprehend object relationships in images.

Avoid complex tasks involving multiple objects, as the results may be humorous or unexpected.
Simplify the tasks to ensure more accurate and reliable image generation

Why you need to learn prompt engineering:

Importance of Prompt Engineering:

Prompt engineering is an accessible skill to learn but requires effort to master.
It demands patience for trial and error, as well as luck to generate captivating images.

Leveraging Model Advantages:

Understand the model's strengths to generate high-quality images.
For example, Titan excels at depicting uniforms, sunglasses, and models in sunny environments.

Avoiding Model Limitations:

Identify the model's weaknesses and avoid utilizing them.
For instance, Titan struggles with hand gestures when holding cups or depicting closely grouped individuals.
