The screen and its features.

Size and résolution

Probably the most important criteria for your choice of digital photo frame.

The size can vary from 3.5 inches (9cm diagonal) to 10 inches. Know that 7 inches corresponds to an image size 10X15. Again, the screen size depends mainly on your financial resources. You can even find digital photo key rings with a screen size of 1.4 inches.

For resolution, the formats are 640 x 480 800 x 600 1024 x 768 1280 x 1024. Of course, for a photo size 640 x 480, the sharpness of the image will be poor at a screen resolution of 1280 X 1024, because the image will be "diluted" in the frame, ie pixelated. The higher the resolution, the higher you will need large size picture. Remember that a 1GB card can store up to 390 photos 2.5 Gb (or 2592 x 1944 = 1 photo of a digital camera of 5 megapixels).

 
Other features

The density of pixels: the more, the greater your digital photo frame will restore the original photo (with less "grain" as possible)

The pitch: it is the space between pixels. Plus it is small, the better. This is an index of the pixel density.

Number of colors: it has a strong impact on the rendering of the photo. Screens low quality have a few thousand (usually 256 000) and displays of good quality will have several million.

Contrast Adjustment: especially the function of automatic contrast adjustment will improve the display of your pictures by adjusting the contrast to light conditions.

The angles of view: shows the angle at which they can position themselves to view images. The higher the better.

Contrast ratio: the difference between white and black on the screen. The high figures are interchangeable meilleurs.cadre

The style or look of the frame is a parameter that varies greatly and depends only on your personal tastes. Some models have interchangeable colored bezels.


Style of the screen you can find screens size TV type (4:3) or film (16:9) or even 35mm (1:1.5), but beware, the device will automatically mute your photos if they does not fit on the screen. All this is configurable on the device, but it is better to know.

 
Importing photos into the digital photo frame

You can import your pictures in two ways: either you insert a memory card that you previously filled with photos, or you connect your digital frame to another device (computer, digital camera, etc. ...) and you transfer your photos.

The memory card is the easiest to import images into your digital photo frame. Usually the managers accept the same format cameras and similar types of memory card your digital camera. In this case, you insert into the digital photo frame card from your camera. If the memory card is not compatible, then use an adapter (if they exist for your card type). The number of pictures depends on the storage capacity of your memory card.

The internal memory can store a permanent collection of favorite photos in the frame. You can select photos that will parade among the images stored in internal memory.

The USB port lets you connect your digital frame to your computer. The framework will appear on the screen of your computer like a USB key. To you drag the photos you want in the digital frame memory.

Telephone Connection. On some models, you can plug your digital picture frame on a modem (old generation type 56K - sometimes there is no need, the modem is in digital photography). The framework will connect to a website (eg every night) where an album. The album is available on the net, friends, family or others can add photos to your album that you view your home. There will be phone costs, but grandparents who know nothing of flash memory cards and neither the wifi will be delighted. Find: A connection via France Telecom may be necessary.

System wireless wifi or bluetooth to communicate and then send your pictures in digital photo frame without any wires.

 
Displaying photos

Although most users insert the memory card from their latest photos, you can edit your photos on the computer and then transfer to the digital photo frame.

Multimedia options allow you to add sounds or videos to your presentation. You can even save a powerpoint presentation using PowerPoint save as option. Jpeg all the slides in the slideshow. Then you rename the images for the slides they appear in the correct order, then you forward and you enter the transition time between your slides or télécommande.cadre you use a digital camera and remote control

The audio and video outputs let you view your presentation on another system such as a TV. If you use a sound with your slide, the quality of the speaker will be an important criterion in your choice of digital photo frame.

Beware of video formats.

A remote control can be an interesting element. There are even touchscreens.

A clock or calendar can make attractive setting if you do not scroll through photos.
