Thank you Paul and John, I am looking to see if I can have a permanent solution to the problem rather than manually stretching each time I load the image. Someone has told me to to save the image with a lookup table before viewing in ArcMap. Could someone please show me how to do that in PCI? John, You said: "Try building image statistics in Arc for each channel in the pix file.". How do I do that in ArcMap? Thank you. Awula Ayelebi I am using ArcMap version 9.2. I have pci pix format images. I created these from merging different bands (using the Translating and Transferring Utilities in Focus) When I view them in ArcMap they look dark and visually not good, no matter what bands I chose for the RGB. However the view looks good in PCI. What am I doing wrong? Do I need to instal pix plug-in to ArcGIS to correct this or such a recent version of ArcMap should already have it? Or is there a better way of combining the various bands into one image? Please help.

By default, PCI applies a contrast stretch to an image on load. ArcGIS only applies an automatic contrast stretch to .img format images. To apply a contrast stretch manually, go to the layer properties -> Symbology –> Stretch -> Standard Deviations. Generally the image looks better if you also choose the option “Statistics: From the current display extent”

Awula,
Try building image statistics in Arc for each channel in the pix file.
