This is a low-resolution hillshade of an area in Israel, about 4 kilometers on each side. This hillshade is upscaled from 30 meters per pixel.

Also included in part of the image is a high-resolution hillshade. Your final product should match the look of this high-resolution area, including the level of detail. Aim for detailed, smooth natural shading rather than countour lines. You can change some of the high-resolution area to blend in appropriately. Make sure there's a smooth transition between the low- and high-resolution areas; there shouldn't be a sharp line where the two meet. It should look like one continuous image.

Especially match the luminosity of the original so that the whole image isn't too bright or too dark.

Enhance the detail in the low-resolution area plausibly (especially drainage). The detail should reflect detail at approximately 1 meter per pixel, consistent with the high-resolution hillshade.

Don't exaggerate the vertical relief. If there's subtle or mostly flat elevation, for example, don't make it look hillier than it is.

There should be no structures, roads, or anything human-created--you're recreating the pure, smooth, natural terrain. Especially ignore roads.

### Each of the below sections is added as needed, depending on the tile

In the flat part of this image, DON'T ADD extra detail or stippling. Areas of flat gray are MUCH BETTER than artificial detail. In the flat area, keep it a smooth gray that blends smoothly into the surrounding pixels. Take special care to match the luminosity of the flat area with the luminosity of the pixels immediately surrounding it, without changing the luminosity of the high-resolution pixels; there shouldn't be a hard line where the high-res and low-res pixels meet.

Keep the drainage in the flat part extremely subtle, almost nonexistent. Prioritize blending in with the flat pixels. Focus on matching the color on the left and top.

This image contains a transition between hilly terrain and flatter terrain. Be sure to manage the luminosity difference here--match the luminosity of the hilly pixels you're generating to the high-res hilly terrain and the luminosity of the flat terrain you're generating to the high-res flat terrain. Don't let the flat areas get too dark or the hilly areas too light, and vice versa. You're making sure that it looks like a unified image with no hard boundaries, that everything blends together perfectly. Use the high-resolution pixels as the anchor for your overall luminosity: don't change the luminosity of the high-resolution pixels, and make sure their luminosity transitions naturally and structurally into the low-resolution pixels.

In this case, you're just blending in the flat rectangle in the middle of the image.
