What is creative hard sketches?

Creative hard sketches refer to illustrations that use distinct, well-defined lines, hatching, and shading to create a high-contrast, visually impactful image. Unlike softer sketches, they prioritize clarity, structure, and a sense of depth through precise linework.

How do I use BasedLabs.ai to generate specific types of hard sketches, like architectural renderings?

After uploading your initial sketch or choosing a base image, use the 'Style' prompt to select architectural illustration styles, specifying elements such as 'blueprint' or 'isometric perspective.' Adjust the 'Detail' slider to control the level of intricate linework and hatching used to represent building materials and structural details.

What's the difference between 'soft' and 'hard' sketches generated by AI?

Soft sketches tend to use blurred lines, gradients, and less defined edges, often prioritizing mood and impression over precise detail. Hard sketches, on the other hand, are characterized by sharp lines, distinct shading, and a focus on clearly defining forms and textures, leading to a more technical or graphic aesthetic.

How can I control the level of detail and texture in my AI-generated hard sketches?

Use the 'Texture' and 'Detail' sliders in the BasedLabs.ai interface. 'Texture' allows you to introduce elements like cross-hatching, stippling, or screentones, while 'Detail' controls the complexity of the linework and the number of visible lines used to define forms and surfaces. Experiment with values between 50% and 80% for optimal hard sketch aesthetics.

What output resolutions and file formats are supported for creative hard sketches generated with BasedLabs.ai?

BasedLabs.ai supports output resolutions up to 4K (3840x2160 pixels) for generated hard sketches. You can download your creations in common formats like PNG for lossless quality and transparency or JPG for smaller file sizes suitable for web use.

How to use creative hard sketches

Steps to get you started in BasedLabs.

Step 1

Upload Your Initial Sketch

Start with a basic outline.

Begin by uploading a hand-drawn sketch or selecting a base image. Ensure the sketch has clear lines and defined shapes. You can even upload a simple photo as a starting point, and the AI will interpret the forms with hard sketch rendering. Use the 'Clarity' setting to dictate how closely the AI adheres to the source material.

Step 2

Customize the Style and Detail

Refine your vision with specific controls.

Use the style prompts to dictate the aesthetic of your hard sketch. Examples include 'technical illustration', 'cross-hatching', or 'engraving'. Adjust the 'Line Weight' parameter to control the thickness and boldness of the lines used in the sketch. Heavier line weights are ideal for bolder, more graphic hard sketches, while finer line weights are suited for intricate detailing.

Step 3

Finalize and Download

Export your high-quality hard sketch.

Preview your generated sketch and make any final adjustments. Use the 'Refine' button to generate variations if needed. Once satisfied, download your high-resolution hard sketch in your preferred format. Remember to experiment with 'Seed' values to explore variations on the same initial style and settings for design exploration.
