Workflow | Differences Between Preview & Export

I have been repeatedly frustrated that the preview and final render bear no resemblance to each other. Preview looks great but the render is over processed.

The issue is consistent but is fixable by changing the original pre-render image to a larger size.

Took me a while to figure it out. Might be useful for others who are having similar problems.

I sent a bug/fix report to Topaz with sample images. Unfortunately I don’t know how to add them here.

Hello!

I’d like to explore your methods.

What is your process for adding pixels to the original image’s dimensions?
If your source image is 1024×512, what are your steps for making it 2048×1024?

A note to all:

We generally do not recommend using Recover or Redefine on images with dimensions larger than 1024×1024.

The differences between preview and export are an expected result.
The preview boxes provide a crop of the image to the AI which it interprets differently than if all of the pixels in the image are being interpreted.

The development team is investigating ways to create different solutions.

Not sure if this solves your problem but…

My workflow usually involves Ai rendered images at 2048x2048 or close to it. I use Faststone (awesome free image viewer/editor) and reduce image by 50%. I would use the same software for resizing smaller images to larger. Pop the 1024x1024 image into Gigapixel and done.

Honestly though my original images are usually bigger than 1024x1024 unless I am using Recover on a low res or poor quality photo.

Thx for explaining why the preview is different from the final. Makes sense now that I think about it.

Hi.

Quick tip; Gigapixel has the ability for downscaling as well as Upscaling images so, no need to use another application

Simply open the image in Gigapixel then, look to the right of the Preview Area you’ll see the Side Panel, at the top of the Side Panel is the Navigation Window.

Now just below the Navigation Window you’ll see Upscale with 1x, 2x, 4x, 6x and Custom and below that is the Scale Factor with a number on the right

Click on the number to highlight it then, type 0.50 and press Enter to scale your image One Half it’s original size or type 0.25 and press Enter to scale your image One Quarter it’s original size then apply Redefine or Recover.

Once you’re done simply click on the 1x Upscale or type the number One in the Scale Factor to enlarge your image back to its original size

Hope this helps

Hello!

When Recover or Redefine is involved, we definitely recommend resampling the image below 1024px. And many times, going even smaller can create even better results as image details are condensed.

On the broader topic of cropped previews vs full exports:
It is expected behavior that a cropped preview (small, medium, large) will produce different results from a full render or export. This is due to a small sample of the image being processed and interpreted versus the whole image being “seen” by the AI to create a result.

so is the upscale option a different process to redefine? I always thought it upscales with the redefine not a separate process?

Hi Richard.

No Redefine doesn’t Upscale Images it quite literally Redefines the image and has been designed for very low resolution, blurry, extremely cropped or heavily compressed images, and AI-Generated images plus anything else you can think of that is of low quality.

The recommended workflow for Redefine is to use or reduce your image to one megapixel 1024 x 1024px or smaller to get the most optimized result.

Then, apply either the Redefine or Recover Enhancements before Upscaling your image using one of the methods below

As I’ve already mentioned, Redefine quite literally Redefine plus add definition and texture back into all types of images.

Redefine also, has a Creativity slider with six levels of enhancement,

Creativity Level’s 1 to 2 are best suited for adding definition and texture back into images that are soft, blurry or low quality and can also, be used with Face Recovery.

With Creativity Level’s 3 to 6 Face Recovery is disabled because, at the higher level’s the image will start to be transformed by, generating and adding information into the image that wasn’t there before and the higher the number the more surreal the image will become hence, the name Creativity.

In addition, from level 2 to 6 you’ll have access to the Advanced Settings where a text prompt box will be provided for adding information about your image or otherwise basically, you can take your imagination to the next level.

Topaz Photo AI’s Super Focus on the other hand, has a similar process when Focus Boost is applied by Downscaling the image then, applying Focus Boost before Upscaling the image back to its original size again.

But, unlike Gigapixel, Photo AI, will Downscale the image apply Focus Boost and Upscale image back to its original size automatically during the Rendering process.

Hope this helps
