I could easily imagine that there is a bent pin in the slot for the memory card. No card is seating properly and so you get the error message. Look in the slot with a flashlight. If you see a bent pin (more likely on an end rather than in the middle), straighten it very gently with a tiny flat screwdriver, such as is used to fix eyeglasses. I had this problem on a memory card reader and was able to straighten the bent pin very easily.

I agree totally with other replies telling you to become expert with your specific camera. Very few people do this. Check out YouTube videos on your camera. When you're proficient with the hardware, read Photography and the Art of Seeing by Freeman Patterson. It will likely improve your photography more than any other single book. Or, as an alternative, shoot for six months, then read it. You will be amazed at all the great shots you missed.

I would become expert with a single editing program (e.g., PhotoShop Elements) and ignore all the rest. You will accomplish far more by being really, really good with one program than mediocre with two or three, even if they can do additional things. The only exception to this rule is to get Portrait Professional if you will be doing a lot of close-ups with people. It's easy and superb.

Sam's Club also prints poster sizes. The quality of the ones in their store near here is excellent. I am working on a montage to have them print for me.

As a general statement, I would shoot virtually all indoor shots with a flash in a landscape mode, not vertically, with the flash to the side of the camera. It's easier to crop the photo to a portrait layout than it is to get rid of the harsh shadows caused by the flash on the side. I bounce the flash off the ceiling whenever possible. Be wary of rooms with red, orange, green or yellow walls. It's tough to get rid of the color castes, because they're often not uniform. Also be wary of different sources of light--incandescent, fluorescent, daylight and your flash. They can be a pain. I would also recommend lithium batteries. They're costly, but last for an incredible number of flashes. eBay is often the cheapest place to buy them.

I use both CDs and DVDs for backup as well as a cloud service (Carbonite) on both our computers. Last year an electrical problem fried both my internal HD and my external HD at the same time--and they were on a UPS with a line filter. No data could be recovered from either.

When we go on long trips or have all the children and grandchildren here, I take many photos and then create photo calendars for the next year for everyone. People keep my calendars forever. I use a Lexmark C534N color laser printer. It is inexpensive to buy and operate. There are probably even better ones out now; I have had it four years. I had an Ibico binder, but gave it to the local college. The plastic combs are only a nickel or so each and you can borrow a binder or have your local office supply bind them for you.

The first thing to acknowledge is that there are limits to what any (or most) of us can do with a photo this bad. Second, it can be improved. You know that her blouse is all or mostly white. Paint it white (gently). You know what color her skin is. Using an eyedropper, select that color and (gently) paint her skin. You know what color her hair is, so select a spot and (gently) clone the rest of the hair to that color. Zoom in and sharpen the edges. I would leave arms of other people almost as bad as they are, to de-emphasize them.

Before you start any of these actions, I would use file and Save As and save the file as a TIF file with a different name. Do your editing ONLY on the TIF file and your original file will be unaffected. When you are done or have had enough fun, save it as a JPG file to be reprinted. Many drug store, etc. machines do not handle TIF files. Some older ones will not even see JPG files on the same CD with a single TIF file.

A totally different approach would be to take the print to a local photography club meeting and ask if someone could help you. I wouldn't be surprised if someone really good would take this on as a personal challenge. A bottle of Scotch or some other gift would be appropriate.

This looks like a nice photo that was probably cropped and enlarged beyond all reason. If it were a digital file, it would have been shot at an ISO way too high. The overwhelming noise is the result of both actions.

I think you have two excellent photos. The brown haze behind the adult bird could just be a reflection in the water of a tree trunk in the distance, but it is disconcerting--almost like a poor print job. I would remove it, which would take probably less than a minute in any editing program on the market. The wing feathers of the adult bird are blurry, which could easily be from wing movement. The young bird, however, is not moving but is also out of focus. More depth of field might solve the problem. It would also help to focus on the parts of the subject closer to you, since more is in focus behind the spot focused on than in front of it. There are two spots on the second photo near the center--one white and one black. They could be something in the water. Whatever the cause, I would remove them, since they take away slightly from the great subjects. I hope you understand these comments are about details, which just reinforces your fine work. Good job!

The bird in the first photo is not in focus. It looks like the chain link behind the bird is the focal centerpoint. I would suggest trying to focus on the bird's eye or on the wing--anything but in back of the bird.

I would worry less about the lens than about post-wedding editing software. If you shoot at the highest resolution, you can crop whenever needed. With PSE, you can do wonders just with the levels command. In addition, get a trial copy of Portrait Professional. It will do wonders for facial photos. The bride will thank you forever. Overcast days are great for portraits. Flowers and leaves are more beautiful with rain drops.

The best book I have ever read on photography is Photography and the Art of Seeing by Freeman Patterson. It will help you see things you have never seen before and will literally change your work. What is your candidate for the best book?

When shooting groups of people, my rule is at least one shot per person plus a couple extra for good measure. That isn't original with me. I took a photo workshop a few years ago. Our first assignment was to put the camera on a tripod and take at least 50 shots without moving the tripod. At a nature photography class, an assignment was to put the camera on a tripod before we got out of our car and to shoot 3 rolls of film without removing the camera from the tripod. It's amazing how many fewer shots you take when you take the time to analyze the scene, move the tripod to get the best perspective and angle, etc.

Nice shot, except that the verticals aren't vertical. This can be corrected in a matter of seconds in PS, PSE or probably any other editing program. Just rotate it clockwise a couple degrees.

I would go one step further: Did you even have a memory card in the camera when shooting those images? Many digital cameras have defaults set to allow photos when there is no card in the camera. Check your menus and change this setting if need be. If you didn't have a card in, the photos might have been recorded to permanent memory in the camera. Check this also.

I would suggest two other possible causes of the problem. First, did you format the memory card in the camera before using it? If not, you should expect problems such as this. Second, on many, many occasions, I have copied photo files from my memory card to the computer, but not all were transferred, though all were selected. I routinely copy them twice, then compare the number of files on the card with the number in the directory on the computer. I simply expect problems. This latter problem is particularly likely if you use a microdrive for your memory card. Fortunately, microdrives are mostly ancient (6 years or so) history.
