The available mirrorless camera has a maximum resolution of 8192 x 5464 pixels, which translates to approximately 29 x 19 inches at 300 pixels per inch (ppi) when printed.

In 400 megapixel mode, the camera captures a series of images and then combines them into a single high-resolution image with a resolution of approximately 16,384 x 10,922 pixels.

Assuming a print resolution of 300 ppi, the largest physical print size possible from the camera in 400 megapixel mode would be approximately 55 x 36 inches. However, it’s important to note that the exact print size achievable may depend on factors such as the printing technology and viewing distance, and the final image may need to be downscaled or cropped for optimal quality.

Using Topaz Gigapixel AI the image height can be extended x6 to 330 inches which is now too tall for exhibiting. At a height of 1.85 metre / 55 inches the multiplier doesn’t need to be x6, Nearer 1.3 (1.324) would suffice especially when the print wouldn’t go to floor level.

Update on making immersive test prints on an Epson 180 / 360 ppi A2+ printer:

Assuming a print resolution of 300 ppi, the largest physical print size possible from a camera in 400 megapixel mode would be approximately 55 x 36 inches. However, to refine the size for an Epson printer that operates at 360 ppi, we need to adjust the calculations. If you’d like to print at a larger size without noticeable loss of quality, 180 ppi can be used.

First, let’s calculate the maximum print dimensions at 360 ppi: To calculate the dimensions, we need to know the pixel dimensions of the 400-megapixel image. Assuming a 4:3 aspect ratio, a 400-megapixel image would have dimensions of approximately 23200 x 17400 pixels.

At 360 ppi: Width: 23200 pixels / 360 ppi = 64.44 inches Height: 17400 pixels / 360 ppi = 48.33 inches

So, at 360 ppi, the largest print size would be approximately 64.44 x 48.33 inches.

Now, let’s calculate the maximum print dimensions at 180 ppi: Width: 23200 pixels / 180 ppi = 128.89 inches Height: 17400 pixels / 180 ppi = 96.67 inches

At 180 ppi, the largest print size would be approximately 128.89 x 96.67 inches.

However, the available printer can use roll paper but has a maximum width of 17 inches. To print the maximum size, you would need to print the image in strips that could be joined together side by side to achieve the maximum resulting print width required.

At 360 ppi, you would need to divide the width (64.44 inches) by the maximum printer width (17 inches): 64.44 inches / 17 inches = 3.79 strips (round up to 4 strips)

At 180 ppi, you would need to divide the width (128.89 inches) by the maximum printer width (17 inches): 128.89 inches / 17 inches = 7.58 strips (round up to 8 strips)

So, you could print the image in 4 strips at 360 ppi or 8 strips at 180 ppi and then join them together side by side to achieve the maximum resulting print width required.
