To update the few who responded to my earlier post concerning my PC shutting down when working with PSE 4....

It was my fault....Go figure [img]/ubbthreads/images/graemlins/tongue.gif[/img]

When I installed the memory chip I decided to do some house cleaning on my PC.....(Smart move)
Even went so far as to remove the heat-sink on the processor to clean it.....(Still a smart move)
I apparently didn't get it locked down securely when I re-installed it....(Stupid move [img]/ubbthreads/images/graemlins/blush.gif[/img])

Can you say "High temp shut down"? [img]/ubbthreads/images/graemlins/shocked.gif[/img] Good thing this contraption is smarter then I am. [img]/ubbthreads/images/graemlins/smirk.gif[/img]

Now I have some PS questions.....

1. Does it matter what order you due your post processing in?

Resize...levels...exposure...filters...etc

2. If I print straight from my card,right out of the camera, is it printing at 72ppi or do photolabs/kiosk's up that to 300?

Thanks to all who have helped me, even when you didn't realize you did.

I don't know if it matters which order you go in, but generally I like to crop first, then resize, then make the various adjustments, cloning etc.

I don't think it matters but I do levels, exposure and such first. When I'm happy with that I save as a PSD, then do any cropping and resizing and save as JPG. That way I have a full quality file to go back to later.

A Fuji Frontier printer (one of the most common photo lab machines) prints at 300 DPI. 72ppi is how a monitor would display it. That's why a print will have finer detail than what you can see on the screen. What the printer does is going to depend on how many pixels you have in your original file and what size print you're making.

Example my five megapixel camera makes pictures that are 1920x2560 if you printed that exactly it would be a print that was 6.4" x 8.5". Not exactly a standard size. If you choose a print size smaller than that it's going to down sample your photo, still putting 300 dots per inch on the paper, but making an educated guess on which pixels to leave out. Larger than that it's going to stretch it , again still putting 300 dots per inch on the paper, but adding pixels.

Try this to see. Take a picture, crop it at 4"x6" 300ppi in elements that should give you a 1200x1800 photo, then go back to the orginal and crop it at 4"x6" 100ppi that'll be 400x600. You'll be able to notice a difference right on your screen. If you print them out and looked really closely they'd both have 300 dots per inch on the print, it's just that each dot on 300ppi print would be equal to one pixel and each dot on the 100ppi print would be 1/3rd of a pixel.

Any professionals feel free to correct or add.

It doesn't matter what you give the printer (Fuji and Noritsu for example) it will be resized to fit the printer's needs. In other words if you are asking the printer to give you a 4x5 it will do so and at the required dpi of the printer. (usually anywhere between 240 and 360 dpi) AND IT DOESN'T MATTER how many pixels you give it!!! Now here's the trick: for best resolution give them all the image data you can. Because the resampling algorithms built into printing machines are superior to that built into Photoshop do your cropping to size in PS with the crop tool resolution field empty. This will create a cropped image with no resampling. Obviously cropping should be judicious, making sure the maximum amount of pixels be retained. This is especially important if the image is upsampled to a large size. (The image file from a 20D will produce a 7 x10 with virtually no resampling on a 300 dpi machine)
Do not confuse ppi and dpi. One is for monitors and is determined by the computer and the other is for printers and is determined by the printer.

Thanks Josh,

I will try some of your ideas.

One thing I did do was to print a 5x7 directly from my card without it being touched by PS.

Then I resized to 5x7,changed to 300ppi,Unsharp mask 175%, saved as JPG
Used the same printer/kiosk and ended up with the exact same print.

I am assuming the kiosk may have done some touch-ups to it.

Another thing is my 4x6 are soft with haloing around the light/dark edges.

Is this my shooting, or is it the print process? The images are crystal clear on the screen with no signs of haloing.

Suggestions?

Joe,

Some kiosks do apply some touch ups, Fuji calls it image intelligence, Kodak calls it perfect touch, sometimes there's an option to turn that off. I'm not sure exactly what touch up's it applies, though usually it looks like brightness, contrast, maybe a level's or curves change, and occasionally I've seen it do some slight color corrections.

I haven't used unsharp mask much so I'm not sure how that would effect the photo.

I don't recall ever seeing haloing on a print.

From what I've seen, Kodak's Perfect Touch applies a levels adjustment to the highlight and shadow areas of an image, reducing the blown highlights and bringing up shadow detail, leaving the midtones alone. The maximum amount it can apply isn't very great...just enough to see a difference, which is really all the marketing guys at Kodak are after.

I'm not informed enough on the working of the Fuji's to comment on them.

1. I'm not good in english... I don't understand your first question. Sorry.
2. In different photolabs use different print machines. DPI is differ.
In one machine it can be 300dpi, but in another it can be 400.
Where the machine gets a file at 72 or 180 dpi, it makes resize to necessary dpi. It is better to resize images by yourself. )
