Great tutorial!
Could this Tutorial be extended to include the Automate function? |

| This tutorial was recommended by a commentor when I submitted a too small image and after following your tutorial I was able to maximize the size and successfully submit my photo. Thanks so much for for taking the time to help us newbies. |

I have finally discovered the 'Save for web...' feature of Photoshop, and it is neat, but, I can't make it save the exif info of a picture when using it. [Or when saving an image in progress to PSD or PNG for that matter.]
The alternative for now is resizing multiple times using irfanview till I'm under the 150k limit. How does one keep the exif while saving in photoshop ? |

| I am brand new here, and never opened Adobe Photoshop until yesterday. I am using the version that this is posting about, and I found this tutorial to be incredibly helpful. |

It deliberately discards the EXIF in order to save file space (part of optimizing for the web).
You do not need the EXIF to be present in the entry file you upload for the challenge -- it only has to be present in the original if you have to submit that for validation. In fact, I think the DPC upload process strips out any EXIF present ... |

I use the steps in this tutorial for all my recent submissions. But I ran across a tutorial on another website for a similar function and they used similar sharpening parameters except for the threshold which they left at zero.
How does the threshold get used then in the USM? |

The threshold setting basically determines "how different" in color adjacent areas/pixels have to be before the sharpening effect is applied. The higher the number, the more different they have to be.
In general, if you have large areas of smooth gradients, e.g. skin tones, you want to use a higher TH setting (I usually used 7), or else the contrast will be enhanced everywhere, creating an unpleasant "banding" effect, similar to but not as pronounced as the effect you'd get by reducing your monitor setting to 256 colors.
For photos with a lot of detail -- e.g. trees/leaves -- will benefit from a somewhat lower setting (I usually use 5), so that the sharpening will have a greater effect.
USM basically looks for adjacent areas which are different colors/tones, and then makes the lighter side a little lightetr and the darker side a little darker, making the junction easier to see and thereby enhancing the apparent detail.
The width of those enhanced areas is set by the "diameter" setting, and the degree to which the effect is applied is the "percentage" or "amount" setting.
The settings you use are also dependent on the size of the image -- you need different settings for a 640-pixel image than for one with 3000 pixels (like a print). Basically, larger images need a somewhat larger diameter setting, since there will be more actual pixels representing and specific object in the photo. For example, a rope might be 5 pixels wide in a DPC entry, but 25 pixels wide in an 8x10 print.
Besides "regular" sharpening with the USM filter, there's a completely separate technique called "contrast-enhancing USM" which seems to do just that, though I don't know why. You use a very low percentage setting, a huge diameter setting, and a TH of zero. I generally use settings in these ranges:
Amount: 12%-16%
Diameter: 48-64 pixels
TH: 0
Try it on a picture with an OK tone range but no "pop" and see what it does. I last used it on a photo with some grassy hills and a cloudy sky, and it made a noticable difference. Sometimes I don't even bother adding the "regular" USM step.

| Help! I think I followed all of these steps but when I try to submit, it still tells me that I've exceeded the 150 KB limit. It seems like the problem would be that I didn't go to "optimize file size..." and set it to 150k, but I double-checked and I have done that. Any help for a newbie would be greatly appreciated. |

Try setting it to 149 or 148 to see if that helps. Sometimes it may optimize to ever so slightly above 150k?

Thanks so much for preparing this tutorial - I found it tremendously helpful! I just wish I had discovered it BEFORE I entered my first challenge! It would probably have helped my score a tad as the comments received so far have almost universally mentioned the small image size. Perhaps it deserves a link or mention in the new member e-mails?
Also you may want to update one item. I have Photoshop CS2 and Convert to Profile is found in the Edit menu rather than Image>Mode.
Since I am just learning my way around Photoshop (and posting to the Web), this tutorial was essential! |

| Just thought I'd give this a bump. Judging from the current challenges, it looks like a few folks could use some help in properly sizing their entries. |

Thanks to Joe Daniels who left a helpful comment in my On the Beach entry. I've been using Save As and constantly struggle with pixel size vs. jpeg quality. I'll defintely give this a whirl and it's good to have in the knowledge base!!
Very good tutorial for those that don't know about it. |

| Thank you for this very informative tutorial. I've only had Photoshop Elements 4 since April 2006, and I just started submitting photo's for challenges in August, but the last two photo's have had comments about pixel quality. I did not figure out until I read the Photoshop Tutorial and then this great article that I was saving to the web all wrong. This is wonderul! It should be required reading for all new member's. |

so... just wondering if I'm missing something...
I start with a 3264 x 6448 4.55 Mb file.
after the cropping ( cropping at the most 1/2 of the picture to say 1800 x 1180) and resizing the picture to make the longest side 640 I end up with a 51k file... and not the 150k I was looking for...
I know this means I am loosing quality... but I am following the steps...
any ideas ? |

Dont use the crop tool to get it to size. Use Save for Web.

What quality are you saving at? If using save for web in PS then optimize for file size of 150k. This is set the quality to the required value to keep the file size under 150k. |

| There is only one thing I would add and it may only be me but, to get exact color, even with sRGB, after I'm done editing I have to go to View->Proof Setup->Monitor RGB. Once Monitor RGB is checked you see what it will look like on others screens. It is significantly less saturated and a little less contrasty. It usually requires about a +20 saturation boost but only a slight contrast adjustment. Way back when I didn't have to do this, not sure what happened for the change. I probably just wasn't as picky then. Looks good other than that, very clear for someone inexperienced. |

well... I am using the crop tool just to crop the picture and determine the final picture I want to end up with.
My cropped files, when saved but before resizing for the challenge are usually about 1 to 2 Mb.

I do use the Save for Web option potimized for 150k |

When using the crop tool make sure the resolution box has no value in it...not set to 0 (zero), but empty. |

OK... I think I caugh my mistake...
I was doing the picture resize before the "save to web" part... and then on the "save to web" part I was going to the "size" tab at the bottom and entering the 640 there as well...
thank you all for your help ! |

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.
