Why do the edits made in Picasa not show in Photo Gallery?

Ah, the ways “Of Mice and Picasa” [*]. How the computer mouse works, you know pretty well, but Picasa, now that is a different creature altogether.

When you make an edit to an image in Picasa those changes are not incorporated into the image file. Well, some are, but for the most part those changes Picasa just stores away for its own use.

Here is an example. Let’s say you have a precious photo of that fine wheel on your motor carriage. To show really what a hot conveyance your vehicle is you apply the Heat Map effect in Picasa.

You want to touch it up in Photo Gallery. Low and behold, the Heat Map effect is not there. The photo looks exactly as it did before.

Let’s look in File Explorer. The photo there does not show the edits either. Indeed, the edits only show in Picasa and not in any other program or app.

AskLudwig-160115-02

See that “picasa.ini” icon in File Explorer? That’s your hint that Picasa does things differently.

But you want to share your Hot Wheel with your friends. What to do?

The solution is easy, but something you have to remember. In Picasa, after you have made any edits, do a “Save As…” and save a copy of the image. That image will have the edits incorporated and they will show properly everywhere.

How do I import just certain photos from my camera to my computer?

Microsoft Photo Gallery provides a very flexible import tool. For the easiest way to use this tool, first set up your computer to launch it when you connect your camera. Check this post for instructions on setting up your computer: How do I import photos from my camera to my Windows 7 computer? 

To specify just the photos that you wish to import use the options in the import dialog. When the dialog opens the photos on your camera are shown in groups by the time/date the photos were taken. Import-09The groups that you have not yet imported are checked. Note the Select all option above the listings.

Click this several times to select all or to unselect all. You want them all unselected.

If you do not want the imported photos to be placed into multiple folders, adjust the Adjust groups slider all the way to the right. You will see the results in the main area.

Click the View all xx items link on the right of the listing to show thumbnails of all photos.

Now proceed through the thumbnails and select the photos you wish to import. Selecting works just as you expect. Click to select, click again to unselect.Import-14 

Note that the number you have selected is shown. You may have to scroll down and up if there are a lot of photos on your camera.

When you have made your selections click Import to complete the task.

Why do I sometimes get spots in my photos?

The full inquiry stated that the dark spots were usually seen in the sky part in photos and sometime they were almost indistinct, other times very noticeable. Spots in photoThe camera used was a DSLR and the lens kept clean.

Here are samples of such spots. These five photos (these are enlarged sections) show the same sky and tree at right. They were taken at different aperture settings, as indicated.

You can see that for large apertures (small f/number) the spots are larger and lighter. In the photos at even larger apertures the spots were not noticeable.

This explains the mystery of sometimes getting spots and not at other times – the aperture will, of course, be different for different photos. So sometimes, with a small aperture (large (f/number), the spots are there, and they are not visible in photos taken at large apertures.

These spots are made by very tiny dust flecks on the rear of the lens. Indeed, this dust was almost invisible to the naked eye. When the lens is stopped down the light bundle forming the image at any one spot is very small and even the tiniest dust particle can cast an appreciable shadow onto the sensor.

It is very easy to miss cleaning the rear of a lens. It is not exposed to the elements except when changing lenses, so you might not think about it. Normally we keep the rear caps on, so there are but a few seconds when dust can get on the rear of the lens. Unfortunately, that is time enough. So be sure to not only keep the front lens surface clean, but the rear of of lens as well.

(Oh, yes, I intentionally got dust on the rear element of a lens to take these photos – the things one has to do to investigate readers’ mysteries!)
