There are three main areas:

1. Pixel dimensions. These should be set to match the required print size and DPI(PPI) of the printer. If they don't specify, use 300dpi and pixel dimensions according to your required size.

2. Colour space. Most consumer print services expect sRGB - so use that in Lightroom. Some have specific profiles (e.g. ProAM)

3. Quality. This is how much compression is applied to the image when saving. The higher the quality, the larger the filesize. A quality of 90 is reasonable for print.

I'd recommend performing some test prints first before committing a large amount. When you have something that works, make that an export preset and you can just export away from there in LR.

It does depend.

JPG is usually required (because anything other can be massive).
Sometimes you need to output to a custom colour space profile, i.e. the colour profile of the printer. In that case, Lightroom allows you to output with a particular intent using an ICC profile.

(e.g. I have a "ProAM 18x12" setting in Lightroom that resizes the longest edge to 18 inches at 402dpi with ProAM Imaging's printer profile. Works a treat and saves a ton of messing in PS!)

Some K10D bits reserved.


Any offers or takers for the K10D, *ist-D, DA18-55s, Metz "monster" or Pentax 110 kit?

It's difficult to check at such small image sizes. At these screen resolutions the images look very sharp.

BUT, I can see that the EXIF data was:
1 - 24mm, ISO800, f/11, 1/1000s
2 - 21mm, ISO3200 , f/5.6, 1/3200s

Both of these images could easily have been taken at a MUCH lower ISO - and this would have increased quality and perceived sharpness.

Not sure what Auto-ISO range you have set - or whether you have overridden the ISO - but I would certainly start by aiming for lower ISO. Generally work towards the shutter speed faster than 1/focal-length. (e.g. faster than 1/25 or 1/20 in these shots. A good rule of thumb would be between 1/60 and 1/200s - covering the range of your 18-135 without introducing shake)


A local Pentaxian would be a good start

Some thoughts:

Check your firmware version (hold MENU as you power up). You should be using the latest firmware as Pentax/Ricoh update SR algorithms. Seem to remember that the early K5 SR had some issues (or was it the K7??)

Do you have any image examples? It could be focus issue rather than SR, could be moving subject, or a number of other things. Seeing some 'problem' images will go a long way to giving meaningful comments.

(Thanks for those that have shown interest so far)

..and look at the processing too.

'Cuttingly sharp' for me occurs with a combination of lens, camera technique, and developing techniques.

Some sample images would help a lot to discern where the issues might be
