RE: Thank you, but a bit more help will do

Q) Why does my TIFF image look different in ArcGIS then it does in Focus?

A) When your image is viewed in Focus, it will often have an enhancement applied to it that allows it to be optimized for viewing with the human eye, often removing enhancements to your data will result in the image appearing dark and hard to see. When the same file is opened in most software packages such as ArcGIS it will not be optimized and will appear dark. In Focus you can customize your image and then export it with the visual enhancements preserved so that when viewed in ArcGIS it will appear the way that you want it to.

In Focus set customize your image with the desired enhancement to appear how you wish it to be viewed in ArcGIS.
Right click on your file name (under the maps tab) and select Save As option.
In the Save As window, select your output file name, the file format and the bands that you wish to include in your new file.
Next select the Properties… button for each layer to customize the Output Later Properties.
In the Scaling Option box choose VISUAL option and select OK (repeat for each layer).
Click the Save button to create the new file and when you open it in ArcGIS it should appear the way that you want it to be viewed.

Awula,

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.

Subject: Do I need a pix raster plug-in to ArcGIS?

Hello everyone.

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.

Thank you.
