I am very new to this sight, and not very computer savvy. I have started to download photos into my portfolio. It seems that I do not have them sized correctly because I am chewing up all my space. I have been sizing them no longer than 600 px in any one direction. Unfortunately when taking the photos I have had the camera set to fine and large format. In PS I tried to bring the resolution down but then my image comes out so small. What am I doing wrong?
Thanks ahead of time...

| In Photoshop, use Image Size to make the largest dimension 640 pixels. Then choose Save for Web to create your JPEG (not Save As). The Quality setting in the Save for Web dialog box will have an impact on file size. Usually a Quality of 70-80 will bring your photo down below 150Kb. |

I never use save for web, maybe I do it wrong. But the way I do it is Image>Resize and make my largest side 640 pixels. After that, I just go to File>Save As and then you save the file as a JPG and then it will ask you if you want to compress it. There will be a little slider that you can move and it has a scale of 1-12. As you slide the bar, there will be a number at the bottom that shows how large the file is at that compression. 12 represents no compression (large file) and 1 is high compression (very small). For most shots, I find that somewhere in the 8 and 9 area should bring you under 150 kb and I notice little to no loss in image quality. Again, I could be wrong, but this is the way I have always done it in PhotoShop.

Matthew, I do it the same way. I've never used the save for web feature.
Just about every piece of software has 5 ways to do things though and I'm sure this is Photoshop's contribution to that :-)

The nice thing about save for web is the "save to target file size" feature. You put in the file size you want, and it saves at the highest quality that will still fit in under that size.
I still resize in PS, though - the final steps of my workflow are resize, USM to taste, then save for web. I find I get the best results by saving USM for the very last step before saving. |

I also use an older version of Photoshop and the older workflow. I save my final, edited version as a TIFF, then apply Unsharp Mask, then Save A Copy as a JPEG with my best guess for compression value (usually 7 on a scale of 10). I can then repeat the process if the resultant JPEG is way too big or small, using different compression settings -- It rarely takes more than two tries that way.
As a last step, I usually close the TIFF and DISCARD the changes (sharpening); that way, if the uploaded JPEG ends up looking bad on the web, I can go back to the TIFF and apply different sharpening. I've found sharpening artifacts and haloing to be among the most common "problems" with photos, and I think they often look worse in a browser's display than in the editing/viewing program. |

I use the Save for Web feature in Photoshop 6, and the first thing I do is resize to 640 on the longest side, then go up to Optimize and put in 150 for file size, then click OK. It usually makes the file between 140 and 150 kb. That's probably not the right way to do it, but that's what I've found to work. I only found out how to do that during the Something New II challenge! :o)

You'll get a bit more quality using Save for Web, since that method doesn't embed byte-wasting thumbnails. You'll also be able to preview the image on other platforms (right-click on your image preview- handy for Mac users).
Note that Photoshop CS has a new resampling option (Bicubic Sharper) under Image Size that eliminates the extra step of sharpening after you scale an image down. |
