When will an updated version of PocketLoupe be released?

At this time, there are no further updates planned. We've been developing software for Pocket PC devices since 2001. For now, we're discontinuing further development of our Pocket PC products, most notably PocketLoupe, for the following reasons:

We started a major overhaul of the PocketLoupe code, from which we would be able to add further camera support and some of the features that you have been requesting. This is not complete, and we've decided to halt the effort immediately since we no longer see a way to recover the costs associated with development. Of course, we'll be keeping our eye on the Windows Mobile market, and if we see an opportunity, we'll start up the development effort again! In the meantime, we're shifting our resources to web and desktop platforms that have a larger user base. We strongly encourage you to try the software before you purchase in order to make sure that it meets all of your needs.


Does PocketLoupe run on Windows Mobile 5.0?

Yes, the latest version should run fine, although we have not formally tested on Windows Mobile 5.0. Please make sure to try it out before purchasing to make sure that it meets your needs.


Precisely what file formats does PocketLoupe support?

The latest version of PocketLoupe supports the following image types, as well as others that are not listed. The best thing to do is download PocketLoupe and try it during the free trial period.

Note that actual raw data is not displayed - the large embedded thumbnails are typically displayed for time and memory reasons. If you are willing to provide sample files for any of the unknown or untested types, please drop us a line. Likewise, if you don't see your camera's format here, or you have a different firmware version that does not appear to work correctly, also don't hesitate to contact us. We may need sample images in order to add support, but please email us first so we can work out what exactly is needed. Usually, adding support for new firmware versions is a quick process, and we can often provide a beta within a very short time period once we have sample files.

Why does the latest version of PocketLoupe only run on Windows Mobile 2003 and later?
In order to support new Microsoft Pocket PC functionality, including VGA screen resolutions, portrait/landscape rotation, and other new functionality, we need to use newer versions of the Microsoft Windows Mobile development tools. These tools do not support creating software for devices running versions earlier than Windows Mobile 2003. If you have Windows Mobile 2002 or earlier, check with your device manufacturer to see if you can upgrade to 2003 or later. The download page also has some earlier versions of the software that run on 2002. The latest full release version that runs on 2002 and earlier (v1.60), supports the following file formats, although others MAY work even if they are not listed here:

When I put my card into the Pocket PC, it asks if it should be formatted...why?
-or- Why do the cards I format in my professional Kodak DCS camera not work?
The vast majority of times, this is a temporary problem with the Pocket PC not recognizing the card properly. Simply eject the card, wait a few seconds, then reinsert it again. It should be recognized. In some rare cases, however, this can be due to an incompatibility in the card formatting. The Pocket PC should recognize any standard FAT formatting, including FAT32. However, cards formatted in some cameras may not be recognized. The only current case we're aware of is with recent firmware updates for Kodak DCS professional SLR cameras. At least one customer upgraded his DCS 720x camera to version 3.1.9, after which cards formatted in his iPaq were not recognized by the camera, and cards formatted in the camera were not recognized by the iPaq. However, cards formatted under Windows XP were recognized by both the camera and the iPaq. We have provided a sample storage card to Kodak to assist in tracking down this issue, but have not received a timeframe for any potential fix. We are also unsure exactly which firmware and camera models are impacted.

Why aren't Pocket PC 2000 devices other than the Compaq iPaq supported?
PocketLoupe requires a substantial amount of memory and CPU power to operate efficiently, and standardizing on the processor that Pocket PC 2002 supports means simpler testing and installation, as well as smaller download sizes for all customers.

Why don't I see the magnifying glass icon for zooming in on some images?
Some images do not contain large versions that allow zooming. For example, if the entire image fits on the screen at 100%, and no larger version exists in the file, the magnifying glass is hidden.

What is the "smart scaling" setting in the Options menu?
Digital camera images can be extremely large. On some Pocket PC devices, this can overwhelm the memory and processor. Turning this option on automatically scales down the fullsize image while it is being loaded to keep it to a reasonable size. This reduces the chance of running out of memory, although it can still happen.

What does the dithering option do?
Dithering is useful on Pocket PC devices that support only a limited number of colors, such as the iPaq 3600 series, which uses 12-bit color, resulting in only around 4,000 possible colors. This may sound like quite a few, but the human eye can distinguish well over 16 million different colors. Dithering attempts to fool your eye into believing it is seeing more colors than it actually is. This may have the side effect of making the image more "grainy," but the tradeoff is usually worthwhile. Of course, if you have a Pocket PC device with 16-bit color, it can display over 65,000 colors, and you should not use dithering.

Why can't I see my files in the file list?
The file list typically displays all supported files anywhere on your device EXCEPT those in the \windows and "\Program Files" directories. PocketLoupe can locate files faster without searching these areas, and we couldn't think of a reason anyone would store their digital camera images there. If your files are not in these excluded directories but are still not being displayed, make sure you have the proper file extensions selected in the options menu - only file extensions that have a checkmark next to them will be displayed. For example, if you uncheck NEF in the Options menu, no NEF files will be found. Finally, your image files may be in an unsupported format - PocketLoupe only supports the image extensions listed in the table above - formats such as .BMP, .RLE, .PNG, .GIF, and others are not supported.

Why can't I see the shutter speed, aperture setting, etc. in the info popup?
Although our image library reads most common data from image files, some non-standard files may not be recognized. When this occurs, PocketLoupe displays whatever information it can find, but some information may not be available. If this happens frequently, let us know. Also, if you edit the image, for example in Photoshop on your desktop PC, the camera settings (EXIF) data may be removed when you save the image. Of course, PocketLoupe can't display this information once it is removed from the file. For Canon CRW files, the way some of the exposure information is stored is not standard, but is displayed from the associated .THM file. Without the THM file, some exposure information may be missing.

What is a RGB histogram, and what does it tell me?
A histogram tells you about the image's exposure. Each vertical bar represents the relative number of pixels at that intensity value. Dark images have most pixels on the left side of the histogram, and bright images have most pixels toward the right. By reading the histogram, you can tell whether the image is over or underexposed, or if the scene exceeds the dynamic range of your camera. For example, if the rightmost bar in the histogram is very tall, many of the pixels are at maximum brightness, telling you that the highlights (bright portions) of the image are blown out. Adjusting the exposure to a faster shutter speed or smaller aperture will bring the pixels on the right toward the middle of the histogram, which means there will be detail in the bright areas of the image. For more information, take a look at this more comprehensive tutorial on histograms. PocketLoupe shows the individual color channels in the histogram, allowing you to see the exposure for the red, green and blue channels. This can not only tell you if a color channel is saturated, but it can also reveal color shifts. Note, however, that since PocketLoupe does not read the color profiles embedded in some images, this information may not always correspond precisely to what you get in a program such as Photoshop.

When are you going to support additional file formats?
Feel free to drop us a line at info@glasslantern.com to tell us what other formats you would like to see PocketLoupe support. The major issue for us is getting sample images for all of the different cameras. We're actively looking for raw files from cameras such as the Fuji S1, Nikon CP5700, and other cameras. Please email us first before sending any sample images.

Ack! I accidentally deleted a file from a storage card! Can I get it back?
Probably not, but maybe. Immediately eject the card to preserve the data on it. You'll need to use a disk recovery tool to try and find the deleted file, but it may have already been overwritten.

Why can't I view my Nikon D1 NEF images?
Files from the original Nikon D1 do not contain a large thumbnail image - only later Nikon cameras included this feature in their NEF files. In addition, the small thumbnail is not stored in a standard format, so it it not displayed. Bottom line - PocketLoupe does not currently support NEF files from the original Nikon D1 camera.

I keep getting an error saying the image cannot be read. What should I do?
Unfortunately, although the JPEG decompression library PocketLoupe uses handles a wide variety of JPEG file types, it does not handle all possible variants. If you receive this message often, please let us know what camera/tools you are using at support@glasslantern.com. We may ask for a sample image to add to our test suite, but please wait for us to request a sample image before sending one. Starting with version 1.20, PocketLoupe uses a new JPEG library that should support pretty much any valid JPEG image.
