Nik Silver Efex

Filed under: tools — ejeschke @ 10:37 pm

Just ran across this interesting post on a plug-in for Photoshop called Nik Silver Efex. Check out the video demo on the blog page.

It looks like it has gathered in one place a lot of really great tools for B&W conversions.

I’m a little bummed that this is a Photoshop plug in, however.  First, I’ve pretty much moved away from Photoshop for everything except printing (and I’ll ditch that too as soon as I can find something that gives me good enough control over that).  The way of the future is not in Photoshop–it’s really showing it’s age now.

Light Meters and 18% Grey

Filed under: noted, tools — ejeschke @ 9:47 pm

I was completely under the impression that light meters were calibrated to 18% gray.  Oh, I knew that it was common for them to be off by some amount, but I thought that they were supposed to be calibrated to 18% gray.

Nope.

The VioVio experience: Part 1

Filed under: POD, books, photos, tools, workflow — Tags: , , , — ejeschke @ 6:21 pm

While it is fresh in my mind, I thought I would go over some of the things I went through to get my SoFoBoMo book uploaded and ordered from VioVio.

Coloring at Lava Rock Cafe
The first couple of things I encountered I’ve already mentioned: I redid the photo resolution at 300 dpi and increased the pages by 1/4 inch (1/8″ trim all around), as required by many POD publishers.  Scribus+Phatch made it very easy for both of these things.  Since the photos are stored external to the Scribus document, I simply ran the selects through Phatch, selecting a 300 dpi downsample and then reopened the document and did another PDF export.  No messing around with the individual images just to change resolution.  Sweet!  The 1/4″ expansion was a little more work.  I had to redo the guides on the master pages and then manually move each image over to keep it centered properly on the page.  With a few other tweaks (described below) it took maybe a couple of hours.  Now that I understand about trim, I won’t be caught unawares next time.

Things got more interesting (read complicated) when I got around to trying to set the cover.  VioVio offers a couple of different choices for doing the cover on the book.  Option 1 is after you upload the PDF, to choose one of your pages as the front cover and another page as the back cover (doesn’t matter which ones).  That sounded easiest, but their documentation (a little weak) said that the preferred way was Option 2: to upload a separate image file (not a PDF, but a sRGB bitmapped image) that would be the wraparound cover.  They even helpfully provided a PNG template on their web site.  After downloading the template and playing with that for a while in an image editor, I began to think that route was going to be somewhat time consuming, mostly because I’d have to size and place the images very carefully in the template and then redo the text of the cover that I already had in my PDF file.

After playing with the image template for a bit I decided to just go with option 1.  The VioVio web site happily snarfed up the 40MB PDF upload (not too bad on broadband) and then took me to step 2, where I selected my pages for the front and back covers, carefully heeding the advice that the process would remove those pages from the interior of the book, and making sure that the rest of the pages fell into the right sequence.

It then generated a preview of the cover.  Unfortunately, the web documentation didn’t say that any text on the cover image would be corrupted.  But it was, badly–as in completely scrambled and unreadable.  I have a hard time imagining what process would do that, but in the end it became clear that I would have to provide a straight image with no text for the covers.  I was beginning to have a really bad feeling about updating my PDF and uploading the who shebang over again, when I noticed that they helpfully provided an option (option #3?) to upload separate, new images for front and back covers if you didn’t like the current ones…nice!  A couple of clicks later I had the original images uploaded for the covers.  Another bit of work to type in the title and author, select a font, text color and placement and then regenerate the cover preview.  I had to iterate this process a few times to get something that looked acceptable, and in the end I was not entirely happy with the very limited choices provided for fonts and text placement, etc.  Still, I was determined to press on, and get something printed.

Step 3 was fairly simple.  Just set a few parameters for the title, description and URL of the book on their store.  This is also the step where they generate a PDF preview of the book, which is fairly lo-res and looked terrible.  Even the JPEG that they generated for the book icons are poor.  It doesn’t inspire confidence in the result, I can tell you that.

But in the end, I decided that I’d seen worse interfaces, and as they go, this one wasn’t too bad.  Main lessons here–if you use VioVio

  • All images should be 300 dpi, with the correct embedded profiles.  If they are in RGB form, don’t convert to CMYK.
  • Make your book 1/4″ larger than the desired size, to provide room for trim (trim is generally 1/8″ per side, but can be more).
  • Keep text and images another 1/2″ in from that (3/4″ from any edge) to account for variability in the trimming and printing.
  • Prepare the covers as a separate file or files, preferably RGB images.
  • Don’t put text on your cover images.  Do that from the web site.

Or just upload your images to Flickr and use the VioVio/Flickr option to build the book!

Their prices are low.  I’ll report again on the quality of the books when they come in.

VioVio books via Flickr

Filed under: POD, books, tools, workflow — ejeschke @ 5:25 pm

I noticed during my time on the VioVio web site the other night that they have an option to create a book via a Flickr interface. You know how you can have your photos in Flickr printed at various 3rd party sites via the web services API? Well apparently VioVio has coded up an interface to pull one of your Flickr sets over and print out a book for you.  Sure would be simpler than all that Scribus work I did, albeit with a great deal of loss of control over the look of the book.  Still, given that I was uploading my selects to a set on Flickr, it would have been trivial to make the book from that (and therefore probably not nearly as interesting).  VioVio even generates a lo-res (crappy) PDF preview of the book!

For a quick book, I think that would be a pretty neat trick. Especially if they pull the titles and descriptions over from Flickr and write those in next to the images. I’ll definitely be checking this out.  It strikes me that it’s also the perfect tool for a kid just starting out taking pictures, as my kids are.  They can already hook up the camera and upload the images and print them out on the inkjet.  It wouldn’t be that much more to upload to Flickr and then put a book together.

The whole process is nicely explained in a video here.

Lava Tube

I’m seeing the light at the end of the SoFoBoMo tunnel…

Tip: I’ve found phatch to be very useful for this project. It swooped in off of google to save me in the midst of a nasty downsampling dilemma.

Recommended.

Need a good explanation of Curves?

Filed under: noted, tools — ejeschke @ 10:50 pm

Paul Butzi has a great post on curves on his blog.  Not much new for me there, but a stellar explanation to point to the next time someone asks me about the curves tool.

Later posts explore why dodging and burning tools are too primitive.  You won’t get any argument from me–I could count on one hand how many times I’ve used them.  I do use Levels quite often though, even when I could just use Curves.  When I’m dealing with simple range problems I find the histogram quite intuitive.  I mostly use Curves when adjusting contrast, or for color issues.
