For each photo; try to send the most original, 1st generation file that you can obtain (meaning; not a re-saved version).

Also if the original source of these photos was not a file format, but physical, e.g. paper or film, and you also have the original paper or film, then state so. (The digitisation process is a deciding factor on the results that can be obtained, and in that case re-digitising in a specific way would produce better results). Maybe useful to know if you can get the photos re-digitised.

Also provide the following information :

Desired print output dimensions (Inches/Centimeters) - Approximate
Type of output hardware, e.g. Laser printer, Inkjet / Bubblejet printer, Dye Sublimation printer, Wax Transfer printer, etc. [Model name & numbers if possible]
Type of output paper, e.g. Plain Copier Paper, Glossy Photo paper, etc.
Output colour; Colour or Black & White
Print output software.

I analysed the two sample photos you have initially provided links to, and found; Although the photos are approximately 4000+ by 2700+ pixels in dimension, the actual effective resolution is approximately 800 by 500 pixels. 800 by 500 pixels is also close to the resolution of a DVD still 720 x 576 (PAL), 720×480 (NTSC). The reason why they are so large is probably one of two reasons, either:

The source was small, but was digitised at a high resolution 3200 DPI (Dots Per Inch)
After digitising, the image was enlarged before saving to file

I think the first reason is probably more correct in this case, because if you take 35mm film and digitize it at 3200 DPI, you will have an image of the approximate dimensions of this file (4000+ by 2700+); 1 inch = 25.6 mm, (35mm / 25.6) * 3200 = 4375 (approximetely the size of the largest dimension of the photo(s). But for a digitized version of a 35mm film source the colour quality is very poor. Either digitization was not preformed optimally, or the digitization equipment was of poor capabilities, or the 35mm film was of poor quality.

So from the effective resolution of these images, the optimum print output size, for output at a particular DPI, would be approximately 3.4 cm x 2.2 cm (printing at 600 DPI) to 6.7 cm x 4.4 cm (printing at 300 DPI). Anything beyond that size results in lower quality print output, which is proportional to the extent of enlargement beyond the optimum output size, due to the image being resized to a larger than optimum size. (If you print at a higher DPI you get more detail in smaller space, but as a result the image is smaller, as opposed to a lower DPI where you get lesser detail in the same but the image is larger). This DPI can be called the intended DPI (next paragraph explains why its labeled intended).

But the optimum print output size, is only for printers that can print dots with a unique colour dot (pixel), as opposed to other printers that combine a small square section of dots to visually re-produce a colour dot (pixel), for example a 4 x 4 dot square (e.g. Inkjet / Bubblet). So for the output printer, for example InkJet / Bubblejet, if you find out the size of printer's dot pattern for each screen pixel (e.g. 4 x 4 grid size), and then multiply the output size at the intended DPI (mentioned in the previous paragraph) by the grid size to get the actual maximum optimal output that can be produced at a particular intended DPI. For example:

Inkjet / Bubblejet - Dot Grid Size of 4 x 4 = Size at Intended DPI * 4 (only use one dimension)
e.g. 3.4 cm x 2.2 cm (printing at 600 intended DPI) = (3.4 cm x 4) x (2.2 cm x 4) = 13.6 cm x 8.8 cm

You really lost me man.That's why I've asked for help.I need somebody to modify them for me.Jox told me that what I need is a better definition.
So can you help me or not?

I want the photos to look like this one:
Click on the thumbnail to enlarge.
I can't upload at work a bigger file,but I think you'll understand what I want by viewing this one.
If this isn't ok I'll upload the bigger file when I get home.
The photos are scans from 35 mm slides like you said.I will print them in a photolab on glossy paper.Size of the photos will be 6*8.5 inches.

In descriptive words; what aspect(s) of the photo(s) you see as making the photo unclear ?

Does the quality problem lie in the 35mm film itself ?

Can you get the 35mm film re-digitized (in a better way this time) ?

...if you can, then which equipment will be used, provide make & model names/numbers

For each photo; try to send the most original, 1st generation file that you can obtain (meaning; not a re-saved version)
