Reviews and previews
Sample images
RAW file format
- Dave Coffin is listing on his dcraw page
every RAW image processing software which either is using his decoder
or
use the decoder as documentation (scroll down to "Other Raw Photo
Decoders").
- Some of these packages are free, some are not.
- I have tried out a number of these packages and in my opinion the
Adobe Photoshop one delivers the best performance in terms of image
quality, user interface and processing speed (with some decoders when
you make a change to the parameters you have to wait for a while until
you see the change in the preview window).
- If you use Photoshop you will need CS3 or later versions, because
CS2 (or earlier versions) cannot import the camera raw file filters
needed for the Olympus E420 RAWs.
- Olympus has released a codec
for Windows Vista.
The codec is a piece of software running under Windows Vista with which
Vista can import and display RAW images of all Olympus DSLRs.
- Another good RAW converter is Olympus
Studio.
- Even Irfanview can
decode E420 RAW files, thanks to the dcraw code.
Memory
cards
- The E420 has a dual slot for CompactFlash card (Type I and II),
Microdrive and xD picture cards.
- There is no reason to use xD cards (unless you want to use the
inbuilt panorama function), since CF
cards are cheaper and usually faster.
Firmware
- Firmware updates released so far (can be downloaded here):
- Version 1.1, 30.09.2008
- Improved brightness level of optical viewfinder AF target
points.
Chromatic
aberrations / Purple fringing
- To remove chromatic aberrations you can process the RAW image
with the Adobe Photohop RAW plugin.
- To remove chromatic aberrations with
an image editor (desaturation of the magentas):
- It is very simple to remove chromatic
aberrations from an image. Simply use a photo editor and set the
saturation
level of magenta (also green where this makes sense) to the minimum. In
some images you might have to set the saturation level of red to the
minimum.
It might also make sense to limit the processing to the affected area
(i.e.
select the affected image area and only process that).
Accessories
- The ME-1
eyecup magnifier enlarges the view by 20%. The eyecup incorporates
two lenses and measures 40 x 30 x 12mm.
- The FP-1 Power Flash grip is designed for use with the FL-50
high-voltage pack and can be used in combination with the flash unit's
built-in power supply to provide fast flash charging for an extended
number of shots. The head is can be rotated by 180° for increased
versatility.
- This page
lists all accessories of the E420.
Infrared
photography with the Olympus E420
These sites contain useful information about infrared photography
with digital cameras:
- Echeng.com:
Digital infrared photography - site devoted to digital infrared
photography with image galleries, information about filters and
equipment and links.
- Wrotniak's
Infrared Photography page
- excellent information resource devoted to infrared photography with
Olympus cameras. Information about infrared filters, exposure settings,
focus, post-processing, sample images and links.
- Also see the Infrared
photography page of the Apogee magazine: this is an interesting
general introduction to infrared photography with digital cameras.

External
flash
- The Olympus E420 has a standard flash hotshoe and can
take standard
external flashes (among others the FL-20, FL-36 and FL-50).
- Try out the Metz flash units - cheap and reliable. Alternatively
try the FL-36 or other Olympus flash units.
- See here
for how to measure the trigger voltage of your flash.

Underwater
Photography
- Olympus is currently not offering an underwater case specific to
the E-420, but the PT-E03
underwater housing for the E400 and E410 might fit. Policarbonate,
waterproof up to
40m, takes the FL-36 TTLflash with the PFL-01 & PFL-E01
flash housing. Five interchangeable lens ports allow the optional
use of the Olympus 14-45mm, 14-42mm, 11-22mm or 14-54mm, 7-14mm, 8mm
Fisheye and the 35mm as well as the 50mm Macro lens.
- Olympus also offer several
lens ports needed to use the Zuiko lenses underwater. There are
lens ports for the 14-45, 14-54, 50mm, 7-14, 14-42 and for the E-14
teleconverter as well as other accessories needed when using the camera
underwater.
- The site Digideep.com
is an online directory for digital underwater photography.
- Interesting forum for underwater photography: DigitalDiver.net
Data
recovery
- Jpegdump,
by Kurt Stege, is a free tool to recover deleted images from a memory
card. Recommended, alough it involves more work an e tool of
Convar.
- These software tools are not free, so since Convar's software is
available for free, there is no real need to use them:
- Datarescue
also has a software tool (Photorescue) for repairing damaged memory
cards,
although it's not free.
- Photorecovery
is another tool. Price is $39.95.
Noise
reduction
Exposure information
data (EXIF)
- The picture files of the Olympus E420
contain the complete exposure information (aperture, exposure time,
focal
leng, white balance etc.).
- To read this data you can use these
software tools:
- ExifReader,
by Ryuuji Yoshimoto. Haven't tried the software myself, but it looks
interesting.
Freeware.
- Exif
Image Viewer, by Michal Kowalski. This is the one I'm using.
Quoting
from his homepage:
"EXIF viewer is a simple image
viewer application for photos taken with digital cameras. It's capable
of reading EXIF information embedded in photos as well as little
thumbnail.
Because small thumbnail is already present in most photos displaying it
is really fast.
EXIF viewer can also provide
detailed information about photos (shutter speed, aperture, etc.) and
conveniently
list them for comparison purposes.
EXIF viewer also displays image
histogram. It also features copying/moving and deleting of selected
photos.
Single photograph can be displayed in separate window or in a full
screen
mode."
- Exifer,
by Friedemann Schmidt. I'm using this one too. It can rewrite EXIF data
to images which lost it due to processing with a software package which
doesn't support EXIF. Quoting from his site:
"Exifer is a nearly free software
(you only should send me a postcard if you're using Exifer frequently)
with which you can manage the metadata (EXIF/IPTC) of pictures taken by
digital cameras. Because many image processing software destroys this
metadata
when saving such files, the idea was to create a backup of the metadata
before editing it in any software, and then, after that to restore it
back
into the processed file. With Exifer you can do this very easily. "
Panorama
shots
- Personally I can recommend PTGUI
(which I have been using for years now): not free but an excellent
piece of software.
- Some interesting links:
