Greetings and happy new year. I'm a new member and new to Photoshop Elements, though I'm rounding the learning curve pretty fast.

Here's my backstory: I collect movie props (mostly custom commissioned replicas), and I like to share pictures of my collection. I have a website at www.jhyphen.com. My theme is that I want catalog quality "beauty shots" of each piece against a pure white background.

A couple of years ago I commissioned a professional photographer acquaintance of mine to take pictures of what I had at the time. The results are uneven, because he simply adjusted the quality of the picture against the existing white paper background. Some of the images are spectacular, and some are so-so, with washed out details and uneven shadows.

Over the past few months, I've decided to learn to do this myself. I upgraded from a 2.6 mp Olympus to a 6.0 mp Canon PowerShot SD600 camera (not much for pros, but I'm an amateur pointer/shooter). I bought a nylon light box (Photek Digital Lighthouse) and two small lamps, and experimented for weeks.

So I got pretty good at taking sharp pictures against a white sweep. But the background never seemed as pure as I wanted. After a little research and fooling around, I determined that the best way to achieve the result I wanted is to take the pictures in the light box, and then Photoshop the prop out of the image and into a pure white background.

I read all the tips and tricks I could, and bought a good book on the subject (The Digital Photographer's Guide to Photoshop Elements by Barry Beckham).

I've used all the tried and true image extracting techniques, including magic eraser, background eraser, regular old eraser, magic wand, and my favorite, polygonal lasso. I find that most of the techniques leave something to be desired, often because they bleed into the prop itself. The lasso is the most effective way I've found, but it is tedious and painstaking, especially to mask out curves and other nonlinear shapes. Nevertheless, a little elbow grease has yielded results like the following:

I would like to know what other people do. Some of my props do not lend themselves to such a good result with the lasso or any of the other tools.

One idea I'm batting around is to use a chroma key (blue or green screen) background, like they do for special effects in the movies. The high contrast might make it easier to use the magic eraser, etc.

Anyway, I know that the subject has been covered before, but I wanted to get into some more advanced discussion, and see if there's anything I missed.

By the way, if you visit my website, these are the three items I photographed myself:

The other pictures in the gallery were taken by the pro photographer. Call me biased, but I prefer my own efforts in terms of crispness and presentation. In any case, thanks for reading, and I look forward to sharing techniques.

Hi John,

I saw that your post had no replys so I thought I would jump in with something that may help.

Have you tried making an eliptical or rectangular selection around your props and then using the magic wand tool to select the background within the selection.

I often set a low sensitivity with the magic wand and then add to selection until I have isolated what I want to select. Also having the anti-aliasing box ticked can help to smooth the edges around the selection.

Maybe using the magic wand with a low sensitivity to select the prop and adding to selection may work just as well.

Your idea of using the blue or green screen should also help.

Thanks for the tip and the welcome! No matter how you slice it, it's a bit of work.

Hi John - Welcome to the forum! Your work is great, your selections clean and crisp, realistic...well, darned near perfect! I use all those tools too, and find the magic wand to be great, feathered one px. But always, I have to zoom in and do clean up work, pixel by pixel sometimes. It is painstaking, for sure. I got a Wacom Intuos 3 Graphic tablet for christmas that I am just starting to use. I have a feeling that it is going to make the work of doing selections much easier - at least less repetitively stressful!!!

Wow! I don't have any suggestions on how to make your task less tedious but I think your results are exceptional. Your phaser image is super! :) I enjoyed looking at your website. What an interesting avocation...

Just one thing - the camera will attempt to interpolates the entire scene as 18% grey, even if you shoot a completely white background it will try to turn it grey.

I know there are ways around this - but I've never had to do it so no suggestions. At least it might give you ideas to search for. Also try jewelry or catalog photography.

What I saw looked great.

I use Elements 3.0. I know that 4.0 and up have a supposedly more robust image extraction tool -- Magic Extractor. Any experiences? I could always upgrade if it seems worth it.

And thanks for the kind sentiments. I've actually mastered what little ability I have over the past couple of weeks. It's been a real crash course.

I hope to share lots of tips and tricks over the coming weeks and months. I am such a newbie when it comes to Photoshop and I never realized it could actually be fun -- I'm a lawyer by day and not very "right brained." I'm enjoying the process of tapping into my more creative abilities....

Nice work. Only thing that I would add is that I got a Cameron Digital Photo Box (http://www.boothphoto.com/prod_detail.cfm?PRODSELECT=9&PAGESELECT=prod_detail_data.cfm) that came with blue and green chroma-key backdrops and they do make a big difference in both getting the exposure right and being able to knock the background out cleanly. Usually a couple of clicks with the magic wand does it.

Bit off topic as this is an Elements forum but the soon to be released full Photoshop CS3 does have a couple of new tools that work really well for this kind of thing - a smart selection brush that finds the edges as you select and a refine selection that lets you see what the selection will look like against various backgrounds and clean up the edges, adjust the feather etc. I really like it and I hope that one day it will find its way into Elements.

John, your work so far is fantastic - I would never guess it was "ameteur work"!! You have a talent. Even though professionals use the lightbox, etc. I would assume all objects are selected and placed on a pure white background. Which reminds me, have you tried to add a nice subtle drop shadow for effect? Or played with custom shadows?

As far as selecting... you're on the right path. Each image will be different, but capturing the object in a clean setting is the right start. The selection tools are all available and ready to work in any given moment... use them skillfully as you advance your techniques. I still struggle and probably do my selecting the long way... but it gets the job done eventually! Shortcuts and efficiency come with time and practice.

You're doing a GREAT job....

I really appreciate the encouragement. I'm very interested to experiment with chroma key backgrounds. I've heard the downside is spillage of the background color into the foreground object, but I'm also seeing some plug-ins out there that seem to address the issue.
