Can anyone tell me why when I try to delete the background on an image, it goes white instead of transparent (chequered)

hi,
there can be different reasons ....
now a common reason, if there is only 1 layer in your file...
if you duplicate the layer and work with the dup layer deleting you will then get your transparency indication...
or if your using the just one layer in the file if unlock the the layer
you will then get that transpancy indication .. |

I think jerryb4417 is right. You are probably trying to delete from the background layer.
Look in the layers panel (Window > Layers). If the layer is called "Background" just double click on it. This will promote it to a regular layer. It'll prompt you for a new name - just click OK and it will be renamed to "Layer 0".
You should then be able to delete to transparency.
Let us know how you go. |

Thank you both for your help, I can now delete a background, but there are tiny bits left - how do I tidy it up please 
As I only have PS elements 5 is it worth me getting 7, as I have been reading online it has a magic eraser which is much easier to use.

hi,
as far as the issue your addressing i don't see pse 7 that much of a advantage...
now i don't know which tool/procedure your using to select the area your removing.. makes a difference...
pse has several ways delete areas.. for example your magix wand...
now with that tool you can adjust the tolerance and depending on the image you can eliminate artifacts that left behind...
now this link, although talking about pse4 can apply to pse5, tells you abou some of the selection tools you have avail to help you.. plus there a tutorial

hi,
the magic wand... just play around with the tolorance setting....
as far as what file to save...
if you want to save the whole work flow i save it in psd....
png or tiff is fine also ....
jpg... NOOO ...
first jpg doesn't retain transparancy.... with jpg the transparenct background become white.... smiling... tif and png and gif will retain transparncy just make sure when saving it the blck is checkmarked.
other reasons fornot saving in jpg , it a lossy format... the amoundof compression effect the quality ofthe image ie; finelines mightlook dotted or dissappears, you can get fuzziness ... you can also get color shades shift ...
plus you can get artifacts....
jpg is great if the priority is small file size or for email or websites. |

The format you use depends on what you want to do with the image that you create. Here are some guidelines:
For photos, or images with lots of gradations of color, use jpg (there are lots of jpg files on the web). PNG-24 is also a candidate.
For transparent backgrounds or web graphics with solid blocks of color, use PNG-8 or GIF.
Don't use tif for the web.
I'm not sure that I agree that jpg is great for small file size - it depends on the image and on what options you tweak. A high quality jpg is very big. But also, some images just aren't suitable for GIF because it's limited to 256 colors.
As for having bits and pieces left around, doesn't Elements have an ordinary eraser tool?
Hope that helps. |
