???????? scaning photo to cd .bmp ver .jpeg

[dirtfarmer]

question
in scaning photo to cd, but first i like to know what format is better to save photo in, right now i scan photo and ther siting in adobe photo deluxe, waiting

ok i useing win 98 se and i scan the photo that waiting for me at 155 dpi, how the question would you save them as a .bmp or a .jpeg


.bmp takea lot of space but you can do a lot with them
.jpeg take less space compress, and not so good for working with photo

so please any one your view please thank you

Hey Dirtfarmer,
I guess I would have to say, whatever format Adobe assigns (PSD) should be your first choice. This leaves your photos usable by Adobe.
Yes Adobe works with many different formats but, the best work is done while it is a PSD. After you are done with minipulation, then I would save final product as either JPG or PNG. Check each for file size as sometimes a PNG is a little larger. File size is everything!!!

I'd have to disagree that file size is everything. Depending upon what you want to do with the files quality could be more important than file size

Indecision may or may not be my problem

I would have to agree, file size is not everything, but that depends on the final purpose.

If you just want to send pics to friends and relatives, once it's finished and you know you don't need to do any more editing, jpg is always my choice, almost any picture viewer will open a jpg, file size will be about as small as you can get it. PNG might be good, but if someone else needs to open it you'll need to check to be sure their picture editing or viewing program can open that filetype. The default filetype of one program might not work at all in another program. Bmp and jpg work with almost anything.

If you want to do further editing or send it to someone else for further editing, bmp is a bigger filesize, but allows more editing options.

As stated above, the original file type is usually best for the original editing program, and if you plan to send it on to someone else it might be a good idea to find out what program they plan to use, and save it in a file format they can work with.

If it's to post on the net, then filesize is definitely a consideration. Usually jpg and gif seem to be the most common choices. In that case further editing is not often a consideration.

what i want to do is keep all option open to save to cd, for any time i wish to do some edit enlarging stuff like that


i like the .bmp format as it does give a lot of offer to work on the photo later, but the space it take yuck

I was not aware that the file format I used effected what the photo editor could do. I have always stored as JPG due to file size. One question I have always had is how much is lost, ie if I scan at 300DPI how much compession can I use before I get the same information that I have in a 150DPI uncompessed file?

[kayofcircles]

My 2 cents worth. After you compress to jpg, the pixels are gone, lost, kaput..never to be retrieved. If you save to a "high quality" jpg, maybe you haven't lost too much, but CDs have TONS of room and are cheap (less than a buck for a "good" brand) so why not save in some way that loses nothing??? Bmps are not lossy, but as you said, they're pretty big and unless you're sending the bmp to someone who already has some form of photo editing software, bmp files open in Paint which is difficult because anything over approx 96 resolution is HUGE in Paint and won't print on one page. I suggest you save everything to CD in the Adobe format..losing nothing at all. It is a cinch to open the file, and if you want to send it to someone on the Net, you should easily be able to make a duplicate, make it smaller if necessary (I mean, you don't want to send an 8 x 10 inch jpeg, you know?), and select a compression value that gets a good look, and a good print, without being too "big" file size wise. I use PaintShopPro rather than Adobe, but am sure Adobe has a good compression (without loss) for its files. If you want or need to send the pic to someone via CD or floppy (the old grayscales will fit on a floppy), may I suggest a TIF format? Has compression to it without losing resolution or quality or ability to enlarge/edit, and can be opened in puters with the Kodak Imaging program that came with 98..I assume 98se..and have heard that ME included some other program that should open TIF files. I have often converted psp (PaintShopPro) files to tif files for a friend to open in his ULead or PhotoSuite programs, so if your recipient has a photo editing program..all the better.

integral: Sorry, don't know the answer to your question. But having worked on "repairing" jpegs..which is a nightmare, by the way..I recommend not saving in that format unless you have very limited hard drive space or no CD writer. In a pinch, my friend saved like one or two pics per floppy..which I grant is not real efficient but do-able. My bible on a lot of this kind of stuff is ScanTips (http://www.scantips.com/) which contains a lot of useful info on monitor resolutions, scanning resolutions, photo quality, and puts paid to the whole 72 resolution for jpgs as well.

Point taken from two knowledgable souls like yourselves. Maybe I wasn't clear in my last statement.
When saving a scan or other input source, save original as the filetype your program defaults to (Adobe=PSD, PaintShopPro=PSP...), when you are DONE minipulating it (color, lightness, cropping,...) save final image as the smallest format available.
With the original saved for your editing program, you can always go to it to make any changes. Also, if no changes are to be made, you can save a copy in the desired format for sending or printing, do that task and then delete that copy to save space.
Recommendation: Save all originals to CD, make copy to HDD for editing, do your tasks, then delete from HDD.

OH Yea, PNG is a fairly universal format that few people are aware of. It is viewable by many standard image programs (Paint, Image Preview, I.E.) and almost all highend editing programs. It can be fussy with Netscape, and sometimes produces an oddly large filesize.
Last I heard, many in the industry were pushing for this format again so it should see some improvements in this next year.

i thank all for there advice sure was not going to save in .jpeg but now in ot saveing in .bmp either, i aim now for for .png

i did a test with one photo scan at 155 dpi, of which i going to scan photo, i was think about 300 .dpi but not now

scan photo .gif 159 Kb------.tif 861 Kb-----.jpg 95.3 Kb-----.psd 930 Kb -----.png 574 Kb-------.bmp 815 Kb------.pdd 930 Kb


also microsoft picture it express 2.0 open bmp gif jpg pmg tif but not pdd psd

photodeluxe 2.0 open all 7 file
photoimpact open all but .pdd

i think i going to start use .pmg, a good mix of saveing space with good editing

bassman: Didn't mean to imply that you weren't on target. Probably I am very fussy about saving in a larger format because often I find myself returning to edit again because of new learning and understanding. I can go back to something I did a year ago, and I can do "better" now because I know more..and one hopes that I will know more next year. Plus, I often use the edited photo for something like putting photo into another, or framing, or masking..or whatever and so want the good quality saved..not a jpg.

You're right..I know nothing about PNG except what you just said. Will check into it..I thought my Paint only opened bmp and jpeg files, but will look again. And I need to correct a statement I made..with the jpeg files, the "pixels" are not gone...the quality of those pixels often is particularly in areas of similar color...sky, water, background walls, etc.

dirtfarmer: I am not sure if this applies, but if you need to "convert" the scans already saved to the png format, you might need to make a duplicate copy first. My PaintShop won't go directly from a psp file to a tif file..I get a tif file, but it won't open anywhere. If I open the psp file, "duplicate" it, then save the duplicated file as a tif file..it works just fine, file opens in Kodak or PSP or wherever. Might be a flaw in PSP, but check your png files and make sure they open okay before saving them all to CD.

[scroatbagg]

I would suggest the folowing. TIFF as it give you a good level of image with the minimal amount of loss, you can also save it with compression and to MAC format as well. The only other format is as the ohter have alrady suggested PSD in Adobe, however if you are intending to send these photos to another person and they dont have Adobe then they wont be able to open them. So svae as PSD then edit to TIFF if you want to send them on. As Kay did say "CD'S are cheap"!!

[not_fred]

Pete hit the nail on the head: it all depends on what you plan to do.

All options open: bitmap

Most options open: proprietary format (e.g., Adobe) or lossless compression (e.g., TIFF, I believe)

Some options open: moderate compression (e.g., jpeg at very high quality)

No options open: severe compression (e.g., jpeg at low to moderate quality)

kayofcircles was mostly right the first time. In a jpeg, the pixels are indeed "lost" - that's why its called "lossy compression", using the Discrete Cosine Transform. An approximation of those pixels is recreated when the image is regenerated from the compressed file.

BTW - I watch the sales and cherrypick CDRs. Usually can get them for around 10 cents each. Have sometimes gotten up to 200 for the price of sales tax (i.e., "free"). At the moment, I have a stockpile of around 500 blanks, at about the 10 cents rate. Quality varies, so I use CD writing sw that verifies the disc after writing (by Veritas, via the hp website). I make about 3 - 5% coasters writing a 4x on a high bandwidth machine.
