My First Look At the Plustek 7400 Film Scanner

The Good:

Well priced alternative to a flatbed scanner.7200 dpi scanner (when measured with a target it turns out to be 3800 dpi in both directions which is right in Nikon cool scan territory)

Actual Dmax > 3.6 and can be increased through multiple exposure mode.

The Negative:

Scanning is done through the included Silverfast Se plus software.

Manual feeder so after you load the carrier you have to push it through by hand one frame at a time. This is not really a problem as I hand correct every negative

No digital ICE (not really a problem for me as I don't use it anyway and it doesn't work on B&W)

My Findings:

If you have any form of workflow the Silverfast software is a piece of junk you would have to spend at least the cost of a scanner to upgrade to a usable version. Besides a rather useless raw mode it doesn't have 48 bit per colour save function. The raw mode would be good if it integrated with lets say Lightroom but it doesn't. It's designed to work with another pricey piece of software you have to buy from them. I don't know about you but I only like to scan once and use the file as a master.

To top it off they keep on telling you to read a 500 page manual and strongly implying that if you want to be a pro you are using the wrong scanner software.

The solution is easy buy reasonably priced Vuescan software. The pro has lifetime support, useful raw workflow and can support multiple scanner types.

Scanning B&W I used some nice grainy HP5+ and found out this:

Multi-exposure is effectively a two pass scan with each scan taken at a different exposure, the 2 passes are then blended together. This actually works and extends the dmax and dynamic range for difficult frames. There is a slight but noticeable lose of resolution. most of which can be recovered with some of the hated USM filtering. Not much need for this function with HP5 I will have to wait until I test it on some high dynamic range shot using TMAX film.

The raw scans pre-adjusted with a film profile seem to contain all the tone information with no banding or noise. Thus they can act as masters.

For 3600dpi scans there was marginally better detail and micro-contrast when scanning at 7200dpi at letting Vuescan reduce the output to 3600dpi (down sampling). This seems to be real not some USM shapening slight of hand (USM was off). Makes sense as the measured on a target dpi is 3800dpi and downsizing by 2 is equivalent to multiple sampling without the alignment problems.

As scan time is almost 4 times as long at 7200dpi I will use 3600dpi scans on images that I don't care so much about and 7200dpi down sampled to 3600dpi on images that look interesting.

Also of slight interest was that letting the software convert from the colour scan to BW gave slightly better micro-contrast then converting the 48bit colour to 16 bit B&W after the fact or scanning in 16bit B&W.

I tested the same negative on my Epson V500. The Epson had less then half the actual resolution and more compression in the grey scale. The hp5 film grains were blobs instead of salt and pepper with the Plustek.

Four out of Five approval rating.

P.S. After using the scanner for a few months the quality of the scans has motivated me to shoot more 35mm film.

Top 10 Signs That You Have Gone Too Far When Photoshopping A Photograph

pin_0821-02

We all know that art has no boundaries so how do you know when you have gone too far with the Photoshopping of a photograph? To help you out I have compiled a list of the top 10 warning signs:

Top 10 Warning Signs That Let You Know That You Have Gone Too Far With Photoshopping An Image

10. Only your parents would put it on their wall and you find out later that they take it down when you are not there
  9. Young boys want to have a black light poster made of your image to hang on their bedroom door
  8. Young girls think it's cute
  7. You think it's cute
  6. People you don't know give you crop or cloning suggestions
  5. People you know give you crop or cloning suggestions
  4. Someone says your work reminds them of another person, and it turns out that you can't stand that other person's  work
  3. Someone wants to know what HDR program and Photoshop actions you used
  2. Someone buys it and asks to have it framed in gold and matted with black velvet
  1. Somehow it reaches the top 10 in Explore on Flickr

Last Supper Redux


Roll Over The Image With Your Mouse To See The Original

You spend your hard earned money to pay for a trip to a far away place where no one really knows English just to wait in line to buy a ticket and when you finally get in you find that famous painting you heard so much about is faded, dull and chipped, it looks terrible by today's digital standards.

Fear not as today I will teach you the secrets of restoring these old "masterpieces" from dull and lack luster to the way they should have been in the first place that is if the painter had had any proper art school training.

As an example I will use the painting the Last Supper done by a moderately successful painter (I forget his name at the moment):

Clearly in those days they never heard of the rule of thirds. At first I wanted to crop the image to make the subject Jesus conform to the rule of thirds. But then I realized I could not do a very nice roll over if the before and after images were of different sizes, besides cloning out the odd arms would be far too much work. So instead I opted to use selected focus. Using selected focus allows me to draw the viewer's eyes directly to the subject clearing up all those busy distractions that make the eye wander about. What was the artist thinking wasting his time on all those unnecessary details? Selective  focus also gives the painting a depth of field and 3 dimensionality that the original lacked.

To increase the feeling of magic and fantasy and to repair the chipped paint I applied an Orton Effect filter/action. The Orton filter I applied came with a set of 10 other actions which I purchased from WeripU at only $180. I highly recommend them as they save you a lot of time learning stuff.

Then to give it a more modern update look I applied a cross processing action (good value at only $80 from WeripU). Noticed the richness of colour. The hills in the background window are now a pleasant shade of Irish green.

Still it didn't quite pop so for the final touch I applied a subtle single image auto HDR tone mapping, notice how much better the light is on Jesus' robes when compared to the original. A bit expensive at $260 for the HDR package from WeripU but how can you be state of the art without the latest and best tools. Also consider the money you are saving and the disappointment you are avoiding by not travelling to view the original artwork.

Before There Was Digital and The Naming Of Photographers

Before There Was Digital


The Naming Of Types
(Stolen and poorly adapted from T. S. Eliot)
The Naming of Types is a difficult matter,
It isn't just one of your holiday games;
You may think at first I'm as mad as a hatter
When I tell you, a photographer must have THREE DIFFERENT NAMES.

First of all, there's the name that the family use daily,
Such as Snapshot, Wedding, Nature, Macro or Travel
All of them fun everyday names.
There are fancier names if you think they sound sweeter,
Some for the gentlemen, some for the dames:

But I tell you, a photographer needs a name that's particular,
A name that's peculiar, and more dignified,
Else how can he keep up his tail perpendicular,
Or spread out his whiskers, or cherish his pride?
Of names of this kind, I can give you the most accordant
That name is of course Photojournalism.
A name that is a beacon for both truth and realism
With the names Bokeh and Sharpness being of much lesser importance

But above and beyond there's still one name left over,
And that is the name that you never will guess;
The name that no human research can discover--
But THE PHOTOGRAPHER HIMSELF KNOWS, and will never confess.
When you notice he or she is in profound meditation,
The reason, I tell you, is always the same:
His mind is engaged in a rapt contemplation
Of the thought, of the thought, of the thought of his name:
Of all the names his is the smartest,
His ineffable effable
Effanineffable
That of course is because he's an Artist
Of deep and inscrutable singular Nature.

Silver Alchemy - Xtol Plus Rodinal

There is a certain modern retro look that I have in my mind for a portrait project I have in the works. The Lomo 120 ISO 100 film AKA Shanghai GP3 looks like a possible film for the project For the developer I would like to use Xtol. Xtol looks good but seem to lack a bit of an edge. Xtol's primary component is vitamin C and vitamin C is compatible with Rodinal.  The idea (from apug) is that a pinch of Rodinal in Xtol adds a bit of edge definition which is normally absent because of the solvent action of the Xtol. So this might be just what is needed.

http://www.apug.org/forums/viewpost.php?p=959820

 It's a balance between grain and highlights with the Rodinal and shadow detail with the Xtol. The 2 developers just happen to be chemically and PH compatible. But Xtol is a solvent compensating developer while Rodinal is not.

I use around a 2 minute water presoak at the same temperature as the developer and standard agitation (first 30 seconds and a couple of seconds every 2 to 3 minutes thereafter). So far in an unscientific sampling it looks like I'm on the right track. Very happy with the results:


Sunset On High Park's Grenadier Pond
Kodak TMAX 400 "Xtol 1:2 + Rodinal 1:112 for 10.5 minutes 19c"
 Xtol was meant to be the dominant component yet with the tmax 400 I can see a definite difference in the highlights over xtol alone. I know by my scanning histograms compared to previous work with xtol and TMAX that the DMAX has increased with more highlights and midtone details then what would normally be seen with xtol alone while the shadows are pretty normal for xtol 1:2.

Fuji Neopan 400 "Xtol 1:2 + Rodinal 1:112 for 12.5  minutes 19c"


































 It is less clear that there is any benefit to adding Rodinal to Xtol when developing Fuji Neopan 400 at box speed. I suspect that because it is easy to block shadows with Neopan 400 at box speed using 1:2 Xtol instead of my normal 1:1 Xtol the shadows are closing obscuring any benefits of adding the Rodinal. Upping the Xtol to 1:1 seems to give better results.

HP5 is a difficult nut to crack The first time was far too grainy. The second time worked much better very sharp maybe even too much acuity.

Hard to see at this resolution but good sharp details with the snow grains and just a touch of blotchyness in the deep shadows.  Looking pretty good but I need to get a better baseline before I can make any conclusions.
