ZoomBrowser EX

Got a question that's been nagging at me, but I keep forgetting to ask. I usually use ZoomBrowser ex to transfer my images off cf or sd card and I use it to go through and find the images I want to put through Lightroom. There is a tab on upper left to zoom in the image when viewing a single image but it doesn't do anything. It would be pretty handy if it worked, is my zoomer broken or what? Thanks

Anybody?

Are you referring to the tabs for mode selection, 'Zoom Mode', 'Scroll Mode', 'Preview Mode'?!

It might help if you give a few clues to your question...

• Version number of software
  
• What mode are you in when you see this 'Zoom' ?
  
• Etc.
  

Version number of software is 6.7.0.24. If you view pictures in zoom mode, and you click on one you will get full size window. In that window in the upper left corner you will see buttons to scroll full size images. Next to those you will see buttons with a little magnifying glass, one is plus, one is minus. Mine doesn't work, nor does the image size button below it. Hence my original question. Hope that is enough clues, thank you.

Zoombrowser only allows adjustments on JPEGs. Are you shooting RAW images? If so ZB will only display them at "fit" size and will not allow any changes. You need to use DPP instead.

Ah, thank you. I do shoot RAW, I wondered about that. I actually use Lightroom to edit but I'm using my old pc right now and it loads really slow. So I've been browsing my image files with ZB to see which ones to edit. Would have ben nice if zoom worked to see detail better on some. Thanks for the reply, much appreciated!

If you press the +Magnifier button, you go into the Zoom In mode. If you press the -Magnifier button, you go into the Zoom out mode. To actually zoom in (once you have gone into the Zoom In mode) you click on the photo itself to zoom in, and it zooms in more and more each time you click on the photo.

Thanks Wilt, that's apparently where the problem lies. It hasn't been working for me, but I shoot RAW and it seems it doesn't work with RAW. Thanks for all the replies, guess I should have tried it with a jpeg, but it seems kind of funny that Canon software wouldn't handle RAW files. Thanks Again!

While ZoomBrowser can preview RAW images, its Zoom In feature does not work with them. My guess is that while it can take the low resolution preview and fit it within a window, there is insufficient information to be able to zoom in at all.

Apart from the fact that Canon CR2 RAW files pretty much all have full resolution previews. So it should really be as easy for Canon to show the preview as it would be to show you a JPEG. After all the embedded preview is basically a JPEG image.

To prove that the embedded image is smaller than the full pixel count:

Within the RAW file...

0x0000 Header contains the byte ordering, the version and the offset to the RAW picture
computed IFD#0 this part contains the Exif section, which contains the Makernotes section.
Information about picture#0.
computed picture#0 small version of the picture (one fourth the size of the original), compressed in Jpeg
computed IFD#1 Information about picture#1.
computed picture#1 small version of the picture, compressed in Jpeg
computed IFD#2 Information about picture#2.
computed picture#2 small version of the picture, not compressed
in header IFD#3 Information about picture#3, the full dimension RAW image
computed picture#3 RAW image data, lossless compressed in Jpeg (not RGB data!)

2.4 IFD #0
The first IFD is containing a small RGB version of the picture (one fourth the size) compressed in Jpeg, the EXIF part and the Makernote part.
See Exiftool Canon Makernote for all known Makernote values and meaning.
The picture in IFD #0, for the 450D, has 2256x1504 pixels. For the 40D, the dimension is 1936x1288.

the TIFF tags are:

Tag value

0x0100 / 256 imageWidth 3=unsigned_short 1 1936 for the 40D
2256 for the 450D
0x0101 / 257 imageLength 3=unsigned_short 1 1288 for the 40D
1504 for the 450D
0x0102 / 258 bitsPerSample 3=unsigned_short 3 [8,8,8]

0x0111 / 273 stripOffset 4=pointer 1 pointer to the image data in this IFD
0x0112 / 274 orientation 3=unsigned_short 1 1="0,0 is top-left"

0x0132 / 306 dateTime 2=string 20 "2008:02:16 17:02:52"
0x8769 / 34665 EXIF 4=pointer contains the EXIF sub directory
0x8825 / 34853 GPS data 4=pointer points to the GPS data

To the OP, have you tried the Canon Utilities software to download your images, and Canon DPP to preview them (Zooming works with Raw files)?

I'm asking, although I don't use those tools -- I use Lightroom to do my Import and previews are pretty quickly available and it's quick to delete the non-keepers!

Actually I use Lightroom also, I quit using dpp. I've been using my old pc because I burnt up the ssd in my new one, and its pretty slow. That's why I was previewing with ZoomBrowser because its so fast. Just got my warrantied ssd back so hopefully be back on the new pc tomorrow, thanks!

Near as I can tell, apparently it depends on the camera.

I just used good old fashioned "BreezeBrowser" to suck the jpeg out of a 7D2 RAW, and despite the fact that my copy of BB is incredibly old and out of date, and totally incapable of editing a 7D2 file, it previews and spits out a full res jpeg. (it also happily displays the AF points, ( this is because it finds the installed Canon engine and uses that.)

With most other cameras the jpeg is a fraction of the full size RAW.

I can't think of any other files where it pulled a full res jpeg, but I haven't owned, used or tried them all.

Oh and a little plug for Breezebrowser, it's old and clunky but it's still the fastest Canon RAW viewer out there (it uses the Canon engine!) but it's far more intuitive and flexible than ZoomBrowser.

Thanks for the info Jake! It's been kind of a pain on this old pc to preview raw files to see which ones I want to pp, LightRoom is way slow on this this thing, hopefully tomorrow I'll have the new one back up and running!
