Ok, so I am a newbie round here and can't figure something out from this tutorial/comp rules/elsewhere on the forum.

The rules say that pictures must be taken by a camera which records EXIF data - which mine does of course. However, when I use SFW in photoshop and read the EXIF data on the file created none of the information about my camera is kept; whilst if I just save directly over the original file it is still there.

So my question is, does the file I submit have to contain the EXIF data related to the original capture (I am guessing it does), and if so how do I stop photoshop losing it when i use SFW?

Cheers

Your entry does not have to contain the EXIF. You have to keep the 'straight from camera' original in case you need to submit it for validation.

Ok, great.
Thanks for clearing that up.

Thank you. I have not posted photos because I did not understand how to do it; now I have no excuses.
I enjoy DPChallenge very much and have learned much from it, thanks to all who contribute.

Why is this? What does it do (or not do)?

Does it default to 72 or 300? I have those two defaults set in my preferences.

If you leave it empty, the file simply maintains its current resolution.

If you enter a value different than the file's current resolution, it will resample the image to that resolution.

Not working. I created it so that it was 150kb. It told me to submit a larger file. So then I resized the original so that the largest dimension was at 640. It was then 700+kb. I gave it a try. When I tried to upload it, the error message stated that the file exceeded 150kb. Then further down it stated that I should upload a larger file. Makes no since.

This is wonderful! Thank you so much, what a great help! In one of my entries I could not figure out the way to resize, I barely got it enerted and then when I checked it ,what a screw-up! It was small and crooked.I knew it would score lower than my usual low.Then I worked on an entry for macro and could not get it the right size and missed getting it summited.... Now could someone tell me how to resize a photo to put in the profile pic? I tried to use the same method but when I put 120 in, 90 was not the other #.Is there a trick for it to?

Are you using Photoshop? The trick is to select the crop tool (from the toolbar on the left), then in the dimensions for that tool (up near the top there are two white boxes where you can input values) to 90 px and 120 px. Then use the crop tool to crop your photo. The resulting size will indeed by 90 x 120 pixels and can be used to upload as a profile picture.

Yes, PS 5.0. But I tried this and couldn't get it to work. In the aspect ratio box, I put custom, first try, then no restriction the 2nd try,and the third try I put use photo ratio.Then in the width box 120 and in the hight box 90 each time. Where did I go wrong?

Wow! I just learned so much about editing using my PS Elements 5.0. Thank you so much for this tutorial!

Great tutorial Eddie. Thanks

I also was not sure about the capture sharpening, but I use PaintShop Pro. Is this a specific adjustment, or simply an initial sharpening pass at the start?

A very thorough tutorial. I'd love to see one more generic if you are leaning that way. The newbies who could benefit most from this may be scared off from reading it because the title says it is for Photoshop, not realizing the concepts apply to most similar apps.

Very helpful. I jsut got a new 10 Mpixel camera and could not figure out how to get to the required size. My first submission was very small as a result. Wish I had read this first as it wasen't a bad picture at all.

Thanks again for writing this.

I use an iMac and could not translate the instructions. I have uploaded a few photos on this site
by using a formula provided by another photography site that I thought was standard:
Pixels:
Width 800
Height 533
Document
Width 11.11
Height 7.407

The photos I submitted (one for my first challenge) seemed to have been accepted. Are these totally wrong?
I'd appreciate your feedback. Sorry, I am so technically challenged.

If the pixel size or file size was too large, the site would have rejected the upload. The thing to watch out for, however, is to make sure you do not use too small of an image size. Using a tiny image when you are allowed 800 pixels will get you some low votes. Also watch your compression on the saved file. Too much compression will make a very small file and kill detail and clarity in your image. Adjust the compression (sometimes labeled as "quality") so that your file size is as large as possible, but within the 300k limitation. There's this one jerk on the site who can spot the effects of compression a mile away and he always seems to leave a comment about it.

I'm a PaintShop Pro user myself, so someone else will have to help you with the Photoshop specific bits.

Thanks for the warning. I'll make sure the size is correct. I have no idea what the compression/quality option is.
I'm here to learn and I'm sure I will figure it out, eventually.

You are allowed 300kb for the photograph you upload. If you provided some details on what program you're using, we could help you out with specific directions for how to save a file at the best compression.

It looks like EddyG is no longer around.
Would someone go thru his excellent Tutorial and update it to match today's rules?...Things like a warning on how to move your photo from your camera (card) to your pc without making it look like it has been modified, and the current size allowed...etc.....PLEASE, for those newbies?

I thought this tutorial was very helpful, but it does need to be updated for the current limits on file size and dimensions.

I found this very helpful as well. It provides some of those specific things needed for DPC. It does need updated, though.

I'm using CS4. When I choose optimize for file size and enter 300, my file size still ends up at 384kb. Any suggestions on what I'm doing wrong (because I'm sure it's something I'm not doing right)

I am working on a few tutorials for DPC, including this one. They won't be available until June.

When you do a save-for-web and define file size, you have to click OK. Then the dialogue box disappears and you will see beside your image a percentage figure that tells you what level of optimization you have at that file size. Depending on the complexity of the image, it could be in the 90's or as low as the 60's.

Now, by default, SFW creates the same PERCENTAGE value as the previous setting, not the same kb amount. So if you saved a B/W, very smooth image at 300kb and it gave you 92%, then subsequently saved a very complex, detailed image, it will by default be at 92% and you have to go back into the dialogue box, choose 300kb again (it will already be showing in its field) and click back out.

That will bring your image to the required compression. You have to do this every time.

Great. Thanks for the explanation
 01/24/2011 06:20:36 PM · #100
Can this tutorial be updated to have the dimensions for challenge entries increased to 800 pixels (tutorial states 640) and file size to 300kb (tutorial states 150kb).

This could be confusing for newbies who follow this tutorial prior to submitting their entries.

Much appreciated :¬)
