View Full Version : Problem! Digital Camera Images on a TV...

Hi all - hope someone can help me with this problem - driving me barmy!

I have a D50 and wanted to display the images on my plasma (a pioneer 506XDE). The Pioneer comes with a PCMCIA card reader - so...I got a 6-1 card reader, slotted my SD card in...and...nothing!

After much faffing about, I contacted Pioneer. They said that if the JPEG images are edited, they could loose EXIF information....the only reason I edited them was to reduce them to 2400x1800 which is the max the screen will display. So I decided to reduce the D50 to lower res. to test it (i.e. lower than 2400x1800). It still didn't work!!!

They then advised I should buy some software...TVWriter. This looks like a useful utility (www.david-taylor.pwp.blueyonder.co.uk/software/imaging.html (http://www.david-taylor.pwp.blueyonder.co.uk/software/imaging.html)) to allow you to add EXIF info back into files so they can be redisplayed on your camera after editing, or a TV like mine. I tried the trial version (which adds banners to your images and over compresses them), and it worked...

However, I don't really want to spend £25 just to add in some meta data and do a bit of resizing! Does anyone know a quick fix for my files so I can view them? Any idea what this TVWriter s/w is actually doing?

For info, I use Adobe Photoshop, so I'm guessing it doesn't wipe out EXIF info.

Cheers.

I don't really see why you need to re-size them. The dimensions of your screen should be irrelevant, you can look at 3008x2000 images fine on a LCD PC monitor, and they are only 1280x1024, so unless the plasma screen is doing something very odd, I don't see what the issue is.

The plasma is decompressing the images into local memory...any subsequent manipulation (such as zooming, rotating) within the plasma is done on this bitmap, rather than the JPEG image. It has a finite memory able to store a bitmap of 2400x1800. Any image larger than this simply won't load. It scales images at this size down to the screen's native resolution of 1280x768. Hope that explains it okay. The issue I have is not with resolution, it's the EXIF info or possible the image not being JPG-DC compliant?

Ah, ok. Well, the image size does not seem to be stored in the EXIF info anyway. PS CS saves the EXIF info when you save the pic. Maybe you should ask Pioneer exactly which bit of the EXIF data it needs, because I have just looked at EXIF on a NEF file, then the JPEG at the same res, then reduced it to 2480x something or other and the EXIF data was the same each time, and there was no mention of image size.

Thanks for that. I'll maybe give them a ring...problem is I never seem to be able to get through to someone technical enough who has the RIGHT info!
