Can I get Walmart prints of edited JPEG photos?
I have a 4GB Memory card for my Nikon D40-
I like to edit my photos in Photoshop as far as coloring goes-
if I re-save them color edited on my 4GB memory card in a large enough size,
Can I still get prints of them at, say, Walmart? My camera quality is set to Fine JPEG.
The reason I ask is because once I re-save color edited photos on the card,
Edited pictures won't show up on the preview screen of my camera.
Need to save them to a flash drive or disc
Your camera is not a display device, once you change anything on a photo it took it will not display it. It will however act as a storage device.
Most of the photo places will print from memory cards, flash drives, and CD/DVDs. If it is a microSD card you will probably need to take the SD holder too.
You can but it will be just as convenietn and less likely to cause user errors if you copy the edited files to a usb stick.
Yes, you should be able to get them printed but your work process is a very bad idea!
The reason you can no longer view them on your camera is because they no longer have all the original properties that Nikon "tagged" the files with. If you only have the JPEG format and have edited the picture on the card the original version is replaced when you save it and, in most cases, is totally unrecoverable. This means if you discover a problem in the Photoshop processing you did do you will not have any way to undo it! JPEG is a "lossy" format, which means that each time you save a file in the JPEG format the processing program makes interpretations of any changes and discard any information it considers unnecessary. This is very much like what happens when someone makes photocopies from a photocopy of a photocopy of a photocopy, Each successive copy loses some quality. That is one reason many experienced photographers prefer shooting in RAW format.
Depending on the model a camera's display screen is intended for composing and viewing unedited pictures or pictures that have been edited in camera. Most camera makers use proprietary, secret software for processing their photos so once they are edited with a standard program they are slightly different and the camera's processing engine may or may not recognize/interpret them.
Before you edit a picture you should download it from the memory card to a hard disk, thumb drive or a separate memory card that is NOT used as a camera media card, then you should make an "archive" copy of the original file preferably on a second disk or onto a CD/DVD. That way if the file you edit is damaged beyond repair you have a way to go back and start over. That also protects you from lost or damaged media cards, computer crashes, and many other disasters.
Once you have done that (it doesn't have to be a big deal, if you set up 2 folders one to download your photo files into and another to edit files in you can download your photos to the DL folder then copy the ones you want to edit into thge EDIT folder and you are all set) only edit the images in your edit folder, if you have to start over recopy from the DL to the EDIT folder (and rename if you need to).
To take photos to any place to be printed buy a small capacity, inexpensive memory card and then copy the pictures to print onto that card, that way you do not risk your 4GB memory card by putting it into an unknown processor. It is extremely rare for one of those machines to malfunction BUT would you want it to happen with all of your pictures from a wedding or vacation?
Hope that helps.
Email if you need help figuring out how to do this.
I don't know about WalMart, but most labs today have an online uploading feature. You can upload your photos directly from your computer at home, then pick them up or have them shipped to you.
