50D ok, but not 1DS

[diehard]

Hi all. I use FPV to pixel peep, culling blurry shots before importing them into lightroom. As such, I need to see the full resolution images.

When I view a .CR2 file taken with a Canon 50D, it shows the file in the full 15mp


When I view a .CR2 taken with the 1Ds MkII, the maximum size it will show is 1.6mp


When I press "R", I get the full resolution


Is there a way to have it show the full resolution images without having to press "R" all the time. It works a treat on the 50D shots, but not for the other cameras. I have unchecked the forcing of jpegs in the control panel module, and all other settings make no difference. Got me stumped

FPV Pro works well with Canon 1Ds files, but old Canon cameras store small previews in their raw files for some reason.

FastPictureViewer can be forced to always decode the full image from the raw bits, but it will take more time to open the files and it's not certain that there is any advantage of doing so. OK, I realize it all boils down to personal preferences, try the option mentionned above and see if it works better for you!

The option on the Control Panel applet governs our codecs behavior when used by other applications, such as Windows Explorer, Windows Photo Viewer, Photo Gallery or Media Center.

The same problem happens with a Leica M9 (DNG). Strange enough the same files (1:1 copy) can be viewed perfectly fine on a WIndow 7 Prof. 64 laptop whereas on a Win 7 Ent 64 desktop the problem arises. Pressing R solves the issue but the "always RAW" option will be the missing link (have to try now...)

[Axel]

You should check the post linked above. There is nothing "strange" and the OS has nothing to do with this, but the screen resolution has. The progran uses a deterministic algorithm to decide to use the preview image or not. There is a programmable threshold that can be set easily, as discussed in the other post.

EDIT: Note that you also need to uncheck the "force preview" option in the Codec Pack Control Panel applet that you can find in your Start Menu for the relevant file formats: the program will see the small preview and decide to switch to full raw conversion automatically.

I have observed the same behavior as described in the original post.

I have edited the registry key as instructed by the linked post. But, it doesn't work. I have tried several values:

Decimal 1 = no change.
Decimal 10000 = no change.
Decimal 1000000 (as suggested) = no change.
Hex 0F000000 = no change.

Also, the properties reported by Explorer regarding these CR2 files (since they are derived from the FPV Codec Pack) also display only the properties of the imbedded JPEG and there is no "R" keystroke to fix that (this is actually a bigger issue for me). Removing the FPV Codec Pack and replacing it with the new Microsoft Codecs did fix this issue with Explorer.

Granted, these CR2 files are being generated by an old 1D Mark II so perhaps there is a difference in the formatting of the old versus new CR2 files themselves.

@WesK: There seem to be some confusion: the behavior of the FPV CR2 codec in general is controlled by the Control Panel applet that ships with both FPV Pro and with the FPV Codec Pack. The threshold value set for the FastPictureViewer Professional viewer application - which is discussed here - certainly has no effect whatsoever on Windows Explorer, but the codec's Control Panel applet exists precisely for that.

Removing our codecs was not a good idea as you lost about 2/3 of the metadata items displayed in Explorer, and also lost support for all digital cameras released in the past two years or so, as the MS product is far behind regarding camera brands and models support.

If you are a Codec Pack customer there is 1) a Control Panel applet that let you control the general codec's behavior and 2) a README file that explains everything there is to know on this subject: the solution was to uncheck an option, and the Control Panel applet for the Codec Pack can be launched directly from the start menu, so is the README file

The original post describes something different (not Windows Explorer) and the solution offered too.

[WesK]

I don't think I am that confused I may not have wrote clearly though.

I did have the exact same problem as the OP with RAW files from my 1DmkII. I didn't have the problem with RAW files from my S95 or from my D700--the RAW files would open the raw data and not the imbedded thumbnails.

I do use the codec pack and the fix was to uncheck the "force preview" option in the codec pack control panel as indicted in your edit to the post immediately above mine. Now everything works as would expect it to.

Is there a way to set this option in the viewer without the codec pack?

I am sorry if I caused some confusion by mentioning a coincidental phenomena that I noticed with windows explorer depending on which codec I had loaded and on different machines.

thanks,

wes

Is there a way to set this option in the viewer without the codec pack?

The Codec Pack control panel applet also ships with the FPV Pro without the bundled Codec Pack! You'll find it in your start menu (or in the Control Panel).

In fact, since the beginning of this discussion, there have been a couple of changes in both FPV Pro, the bundled codecs and the standalone Codec Pack that have an effect regarding the behavior described, in particular, the latest "fix" is now use the Control Panel option only, there is no longer a need for the registry setting change descriped in earlier posts, as the viewer has been made smarter in the meantime.

This applies to the current v1.6.213.0 version of FPV Pro and the current v3.1.044 of the codec pack, or later versions, please update to the latest available version(s).
