Darkening and changing image values using imread

Previously I have worked with two radar images that are in .tif format and scaled in 8-bit integers, one of them P-Band and the other X-Band. In the Matlab script, when I use "imread" to input the P-Band image, it opens and the Workspace shows that it is a uint8 array, but the pixel values change a lot and the image becomes noticeably darker compared to the The brightness of the image and the pixel values that are displayed when working with other software such as PCI Geomatics or ArcGis.
The processing I do on the image is also affected. What can I do to correct this?

Hi,
You can try reading the image using read. You can start by creating a Tiff object and then read data from the TIFF file.
t = Tiff('peppers_RGB_tiled.tif','r');
imageData = read(t);
imshow(imageData);
title('Peppers Image (RGB)')
close(t);
I hope one of the two serves your requirement.
