Im not sure how to I should size my prints before going to costco and getting them made. Im looking at getting some 4x6 made for now.

Should I:

1) make high resolution JPEGs that are the same size as the RAWs (in other words not resize anything, keep quality at 10, etc). In this case the costco soft ware would "squish" the file into a 4X6....right?

or

2) resize the images to smaller JPEGs to the size I intend to print (4x6), keeping aspect ratio, quality 10 etc.

What are the bad/good of each?


Also, should I change the DPI to anything other then 350?


Thanks all,
Andrew

350 seems a little higher than necessary - I would say that 300 would suffice. Mind you, if you choose Option (1), then the resolution is irrelevant, of course.

My choice is always Option (2), because I like to be able to accurately sharpen my files at print size. However, other people will tell you that Option (1) is better, because it avoids double-resampling of your pixels.

thanks,

should dpi be changed with the size of image printed?

Well, the only difference between Options (1) and (2) is the specification of a PPI value. If you choose (2) and make your photos 6x4, but don't specify a resolution, then the end result is the same as (1).

So yes, if you choose (2), you need to not only set the width and height, but the resolution as well.

I ALWAYS send the full resolution JPGs to Costco, even for little 4x6 prints. They must love me :lol:

And I do Quality 12 :)

When exporting my image, I output at the required size in pixels. Remember it's not dots per inch but PIXELS per inch. THere is a difference - although in this case I accept we are all meaning the same thing.

Printers print in dpi but images are made of pixels and resolution is measured in ppi.

A 6x4 @300ppi therefore is 6x300=1800 pixels by 4x300 = 1200pixels.

Resize your images to 1800x1200 and you will have the correct size to print your 6x4s at the optimum resolution for print. I never go above 300ppi and often print at 240ppi - the human eye would struggle to see the difference.

With regards to jpg quality, if you save the image out straight from the raw, 10 is fine and you will see no difference in the look of the image but you will see a dramatic reduction in the size (which can be good).
