How To Select The Best Digital Photo Frame by

If you get enjoyment from looking at photographs then the latest digital photo frames are ideal for displaying all of your best your images in all their glory. The quality of the image that is displayed with these electronic photo display devices is actually very impressive. So go and buy yourself a digital photo frame now and have some fun with your photos.

Before making your final choice or selecting your potential purchase you should look closely at the minimum specification that you require for your new photo frame and then choose wisely to ensure you get what you want.

Make Sure You Get A High Resolution Display!

To get a clear, crisp and brightly lit image to show your photos at their best you must look closely at the resolution of the display screen that the photo frame uses. Digital picture frames use a Liquid Crystal Display. These are just like those used in flat panel televisions, but on a smaller scale.

So if the digital frame you are considering does not have good resolution ignore it. Screen Resolution makes such a big difference to the quality of the image that you need to get this right.

Many different resolutions are available and you need a 640x480 resolution as a minimum or 800x600 if you can afford it. It will make a big difference to the enjoyment of your photo collection. Any frame with a resolution below this minimum will not display images as well as the original photo and you will not like what you see.

For LCD photo displays that are bigger than say 9 inches you should consider trying to get the highest resolution that your bank balance can accommodate. A higher resolution will always give you a better quality image. Any frame that seems cheap more than likley has a low resolution so make sure you look at the specs.

Which Aspect Ratio Do You Want?

You only really have 2 aspect ratios to worry about, and these are the standard 4:3 as found in images from popular point to shoot digital cameras, and the 15:9 ratio in found in some digital photo frames.

Because most photo images from digital cameras are in 4:3 format this is the best ratio for displaying your photos as they were taken. A digital frame using 15:9 will have more impact with a cinema-like image as on a widescreen TV.

Unfortunately if you display 4:3 images on a 15:9 digital screen then the top and bottom of the image will be chopped of to make it fit, which you might not like..

Get The Right Memory Card Slot

Make sure the digital photo frame you are thinking of buying accepts the same memory card that you use in your digital camera. Some frames have a multi-card reader, which means they can take several different types of memory card in the same slot, although only one at a time.

Get A USB Port As You Will Probably Need One

Anyone who requires to transfer images and digital photos using a USB cable from their camera or computer to the digital frame will need a USB slot as well. However if transfers using just memory cards is sufficient then there will be no need for any USB requirement.

What Else Do You Need?

There are many other options now available for the digital photo frame, such as wi-fi connectivity to download images from the web, speakers, headphones, remote controls, alarm clocks and many more. These are selected by personal choice and of course you should expect to pay more if they are what you want.

If you follow what we have recommended above and try to ignore the name of the manufacture or brand shown on the product then you will be in a very good position to buy a great digital photo frame. You will get a display that gives sharp images and you will also have enough confidence to find the best deal on what you want.

1/SA + 1/SA' = 1/F
SA = distance of object to lens
SA' = distance of image to lens
F= focus.

So,

1/x + 1/76.6 = 1/62.3

x = 333.7 mm
