Reducing Photo disk size |
|
|
Other than cropping photos to small dimensions (or using thumbnails), what
are the best ways to make photos take up less space and bandwidth so you can
have large photos fully displayed on web pages without it taking ages to
load on dial-up connections?

Take shots with lots of sky showing. |
There is no magic way to get the files real small.
You can help by removing the exif data, but this only reduces the size
a small amount.
The only other thing is compress until it hurts.

Saving as a jpg with just enough compression so that image quality does not
suffer. |

I'm planing on compressing. What low cost software does a good job of
compressing the file sizes without changing the dimensions of the photos? |

Most picture-editing software allows you to save jpegs in a range of
quality settings. Lower quality means smaller files. It also (obviously)
means a lower-quality image. Play with the sliders or whatever in your
software until you find your sweet spot between quality and file size.

Firstly, make sure that you re-size your image to 72 pixels per inch. There
is no need for any higher PPI when submitting photos to the web. If you use
Photoshop you do this by going to Image and then Image Size. Change the
Width and Height as necessary..usually around 800 x 500 will do the trick.

The PPI does not make any differance, only the size in pixels matter.

The pixels per inch have absolutely NO effect on the file
size or how an image looks on a monitor.. None whatsoever..
Do this.. Open an image.
Change the PPI to 72.. Choose [Save As].. Save the image as 72.jpg
Now change the PPI to 200.. Choose [Save As].. Save the image as 200.jpg
Change the PPI to 3000.. Choose [Save As].. Save the image as 3000.jpg
Now look at the images.... Note how the file sizes are exactly
the same. Note how they look identical in your browser..
One Caveat.. Make sure the [resample] box is unchecked.. If you
check this box, you're doing **MORE** than changing the PPI.. You
will also be changing the total number of pixels in the file.
In this case a smaller file will result because there are
fewer pixels. The file and image are smaller NOT because you
changed the PPI, but because you resampled it.

IrfanView does a good job. It's widely used and it's free. You
can select the compression to be used ("JPEG quality") and also
resize the images to reduce the number of pixels if the full
resolution (multi-megapixels) aren't needed for display on a web
page. A 100kb file can provide very detailed full screen images.
The dimensions of the displayed images are best controlled by using
the appropriate HTML tags. |

It seems to me Irfanview is cheap (free) and will do both the jobs on
individual or batches of files.
My uses have been within Photo Shop, and while you may find or develop
different standards, I have found that Save For Web suits my eye: it
strips the EXIF and compresses at your chosen rate.
What I have decided is: for computer display, compression beyond Photo
Shop quality 30 introduces too much distortion; compression at less
than Photo Shop quality 60 adds too little to the viewing experience
to justfy the increase in file size. That scale runs 0 to 100 quality.
The 30-level saves result in a good compromise between quality and
file size.
With no considerable experience with other "compressors", I can't
recommend numbers in other systems, but I reckon values comparable in
ratio to the 30 and 60 would be good starting points.

yup. Amazing what you can do for a web page image with just the right
amount of compression, and say how much reduction in file size saving
at 20% compression can make for website images.
