Pentax users hate photoshop

I always find these discussions to be fruitless. Sometimes I think the detractors say what they say because they do not understand Photoshop and simply use it badly, getting bad results, which then turns them off the package. Then, forever more they say it is not necessary.

This is of course a bit of nonsense. If one takes images in raw, then ACR is absolutely necessary to produce a printable image file. The raw data will always need a degree of work done on it to fine tune the white balance, exposure level and correct slight excesses at both ends of the histogram, I do not believe that even those most careful always take an image that has a perfect histogram straight out of the camera. Digital raw images also need a carefully targetted degree of sharpening, something that is often done crudely in camera when taking jpeg files.

Photoshop does for the digital photographer exactly what could be done for the film photographer in his dark room. It enables the photographer to produce the finest possible final image. But is does so in a non poluting environment with the ability to retrace your workflow right back to the raw image. Non destructive enhancement. Try that with film!

CS4 is a modern marvel, used with intellegent care it is the best tool a digital photographer could have and an essential for the professionals.

Amen to that. PLus the workflow in CS4 is the best out there.

Not a very helpful comment, was it?
You quoted a substantial chunk from my post, and this included several statements. You failed to indicate which of those statements you believed to be untrue. For the benefit of the other readers, could you please do this?
If it will help you, the three programs I referred to (but did not then name) were Photoshop 6, Corel Paint Shop Pro X, and Serif Photoplus X2.
I have just repeated the exercise with a different file and repeat: resizing the image does not change the pixel-per-inch value.
If there is a setting that I can change, that will prevent this from happening, do say so - I am sure that this would be helpful to others.

Hear hear!!!

It's funny how people make a "virtue" out of avoiding something they don't want to learn. For me it was French

It's very little that I will use PS. But from time to time I will for the fun like, crops and cloning. CS3 rocks

I'm probably being thick, but why do you want the PPI to change when you resize your image?

Because you might be preparing the image for a specific purpose. If for a print, 300ppi and if for the web 72ppi.

Some of the values are connected, so it's easiest if you open the Image Size dialog and change some figures, seeing what happens when you do.

Why 72ppi for the web? Resolution is immaterial as far as web use is concerned, it's the actual pixel dimensions that matter.

I think thats a bit harsh, it may be true for some but I believe many people will forgoe the use of photoshop simply because its not for them, I believe I would also be correct in saying the same applied to certain darkrom techniques.
I would wager that those who frequently make use of photoshop to manipulate images are either newcomers to photography or those who have come over from film who also made use of advanced darkroom techniques, the "detractors" as you put it will probably be those who used slide film and enjoyed getting it right in camera, some photographers do like to think of themselves as just that and will avoid manipulating an image wherever possible, even to the point of poo-pooing the software.

I do admit to manipulating some images and even winning competitions with them, but I get very little sense of achievement when compared to one straight from the camera with nothing more than slight adjustment of levels and sharpness.

Each to his own I suppose,

long live photography
down with digital imaging

Because most monitors display at 72ppi and therefore no resampling is required.

Hmm, the Mac traditionally had 72dpi screens, but those days are long gone. Most screens these days are in the 90-100dpi range.

I think the confusion for me is what 'resize' means when DoctorJeff says it. Are you reducing the dimensions of the image (in pixels)?

I don't think the ppi data in images is used by monitors. I think it's only relevant for printing.

You took the words out of my mouth. Mac used to be 72ppi and Windows 96ppi. It is impossible to accurately size a picture for general web viewing as the actual size it appears will depend on the pixel pitch of the monitor being used. The only control you have is pixel dimensions and resolution has no relevance.

Ppi for display on monitors was discussed here - it really makes no difference at all. Ppi for printing is a different matter entirely.

Dr. Mhuni, in Photoshop Elements 4, which will probably be somewhat similar to PS6, if you untick the 'resample image' box when resizing, it will change the resolution as you change the image size. If you keep the 'resample image' box ticked, the resolution will saty the same and the pixel dimensions will change as you resize.

Yes, that was always my understanding as well. Which is why I never change the DPI of my images at all, they always stay at 300dpi. When using them for the web I just change the pixel resolution to whatever I need, without changing the DPI at all.
