I just upgraded from PS6 to CS and have noticed the files from my Nikon D100 have gone from being opened in PS 6 as 3008 X 2000 at 72DPI 41.778" X 27.778" image to CS opening them at 3008 X 2000 at 300 DPI 10" X 6.?" image. I am wondering why it is doing this and how do I change it back, also will this affect my printed output on larger size prints? I have always downsized the images and am concerned as to the quality of the prints if they are upsized.

Any help appreciated.

It’s the same thing. Just change the pixels per inch without resampling and they will match.

What was happening is that PS6 is reading monitor resolution and PS7 is reading EXIF data. But there is no resolution in a digital camera file, just pixel dimensions.

lands,

Larry’s information is correct. But there is a trick to it to keep from hair pulling.

When you go to image size, remember one of the pixel counts (3008), change the LPI resolution to what you want it to be, then go back and change the new pixel count BACK to your 3008. Then save the file in what ever format you desire. All that is done, now, is to change LPI. NO other changes are made to the file, just to the print size (dependent on the LPI setting).

If left alone (there MAY be a trick I don’t know to lock pixel counts) it will change the pixels to produce the same size print but with the pixels needed to match the new LPI. At PS 5.01 through CS has been doing that for me.

I’m not sure why you would want to do what you seem to be suggesting Bill which seems to involve resampling the image and is actually unnecessary in any case.

Just change the resolution in ppi with the resample checkbox off (as Larry said) and there will be no change in the pixel count.

"pixel count" is always the same regardless of ppi.

No need for what you suggest, and seems to resample, as Mick says.

One can change output size (inches) or ppi, with resample off, and "pixel count" stays same, and image is not compromised.

Well I guess that was simple enough, I knew I was gonna feel like a dumby when I asked. Thanks for the help.

All I can say is that when I uncheck resample the pixel counts continue to blank out (no pixels to work with apparently) and the window locks up until I shut it down. I ran into this starting from my beginning (PS-4.0LE-> 5.01-> 6-> 7-> CS) when resample was for up-size and resize was for down-size. Before CS’s resample-sharper, I had been using a different program (Irfanview) to resize (down) when I needed an e-mail sized file and didn’t need to fine tune sharpening for the intended end purpose.

My scanning software (Hamrick’s) lets me set the output file LPI. The pre-Fuji-S2 digital camera automatically set LPI to 300 where I wanted it for that camera. I do not do hand drawn work. And never had too much need for that to work (or possibly understand just HOW it works) until the S2. Then I had to find a way to get the Fuji-EX Converter’s 72 LPI files to 300 and lock the pixel count.

I may be wrong in my thinking, but I could come up with only two things that would be happening, neither being bad. The first was one number in the file’s internal structure was changed (from the old to the new desired LPI) or at worset it was recalculating the file and leaving everything, except for the LPI, as it had been. With the speed at which it takes place, the first seems quite likely. I found no noticeable difference between a 200 K file and a 50 Meg file.

That’s cause your NOT changing the pixels count.

Makes sense, not resampling means not changing the pixel count, ergo not an option.

…and the window locks up until I shut it down.

Then you have a problem for which you have devised a kludgy workaround. Deleting prefs would be the first step.

Then you are not looking close enough!

EEP!

The lack of difference is with the speed of Resample NOT in the quality of the image for prints!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

A piece of a second vs a piece of a second.

NOT

A 2 inch x 2 inch (more or less) picture vs a 9.5 inch x 17.5 inch picture. (The figures in the previous sentence are not for the same picture and are not to be considered as anything other than a quick stab in the dark for the first one with the second set being the size of the print image (2880 setting on Enhanced Matte Paper from my Epson 2200) from the picture I finished last night.

Deleting the Preferences cleared up a different problem last week and may have cleared this one up too with force of habit keeping me in the same (knows it will work but may not be the easiest/best way of doing it) work pattern.

Are there any more disclaimers I need to add?
