Having problems with your Digital Cameras ?

I have strange digital image file size problems. For example, if I upload a 6 mb file to my photo sharing website (Google Picasa) at the highest resolution, it will indicate that it is only 1.8 mb. After downloading the same file from the website, it indicates that it is 1.8 mb, however, the dpi and size of the image in inches, in Corel Photopaint, multiplies out to be the same as the original (96 dpi x 38.67 in vs. 72 dpi x 29 in), and when I resave the jpg with Photopaint, the file size incr


Answers :

Hey Tom; this always hurts my brain, but here goes. Your image file is 6mb. That's the easy part. When it is saved in the .jpg format, it is "compressed" in order to store more images on a memory card or hard drive or CD etc. . Otherwise the sheer size of digital images would only allow a few on a memory card before it was full. Your 1.8 mb file size is the compressed size. When you open the file it is uncompressed to its proper dimensions. The amount of compression is usually chosen to optimize its use. For instance Picasa has to store so many images, it may compress them more than another application. Each time you open, make any changes, and re-save the same image, a small amount of data is lost or destroyed (that may explain why they open up to 5mb in Photopaint). The less compression used, the more "true" the image remains. Most cameras compress the images to about 1/4 their expanded size. That's how a 1gb memory card can hold hundreds of 6mp images, when it could only hold about 170 if they were uncompressed. I hope that helps a little.

Camera: Panasonic Lumix DMC-TZ7 Resolution: 10,100,000 pixels I am selling my camper van on the web. I have taken photos of it with the above camera. However, I have been unable to upload the image files to certain websites due to the large file size. Typically the pictures seem to be 5Mb in size but, on one website there was a limit for file size of 500kb. One site suggested choosing a lower resolution on the camera (e.g. 1024x768).

Dpi issue In the f-Mode menu I have set my camera to the highest available quality, ie: 6Mf. However, when I open the pictures on my PC (in any of the proprietary imaging software), it shows as having a resolution of only 72 dpi. For print purposes I need to achieve at least 300 dpi (600 preferable). This is not a memory issue as I have a 2gBt memory card. Can anyone advise?

My Samsung TL220 lens won't close. It doesn't display an image on the front or the back. However, when I trigger the menu, the lcd displays "No Image File". It does go through and displays all the different menu options, so the lcd must be o.k. Could this be fixed with software or software update or do you think this is a hardware problem? ( I've noticed several TL220 that have this problem.) Is it an easy fix & how much do you think it would take to fix? Thank you.


Well, there must be a setting that was unintentionally set. First, I need you to try restoring the camera to its default settings. Go to Menu settings and then choose Reset. Let me know if this works or not so that we can move forward to other fixe ... Samsung DualView TL220 Digital Camera
