 Two days ago, Peter Moore released the first official Madden NFL 10 screenshot on his blog [link].
These are pretty exciting times for the community and for us on the
development team. For us it is a chance to see what the community
thinks of our hard work to this point.
Some of you may know me from last year, but if not, I'm Michael Young, the Art Director for Madden NFL 10 and NCAA
Football 10. I'm in my second season as Art Director for Madden
NFL and first on NCAA.
I'm also an avid sports photographer, and through my roles on Madden
and NBA Street, I have been able to shoot some amazing events from the
sidelines of big time sporting events, including Super Bowl XLIII. In
today's blog, I'm going to go to really dive into some detail on one of
our new features that you likely will have noticed right off the
bat: Depth of Field. In addition, I will talk about the 9 other Madden NFL 10 enhancements shown in the shot unveiled on Peter's blog.

Depth of Field
For Madden NFL 10 and NCAA Football 10 we
have an all new realistic Depth of Field system calibrated to match
real world cameras. This single enhancement not only improves the
visual quality of the game but it will allow us to reproduce a
broadcast experience unlike ever before.
What is depth of field (DOF)?
DOF is a film/photography
term used to describe the part of an image that appears sharp or in
focus. In the image below Adrian Peterson is within the DOF thus
appears to be sharp while the players in pursuit appear soft. These
blurred or fuzzy areas are referred to as Bokeh. Notice how this bokeh allows the viewer to clearly isolate Peterson from the rest of the pack.
A shot I took of Adrian Peterson as he broke away for one of his two TDs against the Eagles in their 2009 playoff matchup.
How it Works:
The DOF is determined by 3 factors: The
subjects distance to the lens, the lens focal length (In general terms
how wide or zoomed in you are), and the lens aperture. In previous
Madden's none of these were factored into determining the DOF.
Madden NFL 08 was the last time we feature DOF in the game, and
there was simply a fixed point in space with everything beyond it being
simply 'blurred'. See image below.
In Madden NFL 10, there is now both a near and far plane. In
addition, the near and far plane will dynamically adjust based on the
subject's distance to the lens, the focal length, and the aperture. See
image below:
When designing this effect, what we wanted was to build a camera
model so that anyone on the team (regardless of their knowledge of
cameras) could create a shot and the DOF would 'just work' in a real
and believable way. In real life a photographer doesn't build the
camera before he or she can take pictures right? What we had done for
years in our games was develop tools that allowed people to essentially
tweak the insides of the camera, even if they had no idea what they
were doing. This unintentionally allowed people to create cameras that
just felt wrong. One of the most common things seen in games is the
over use of narrow DOF, which I'll illustrate in the images
below. The first is of a cityscape. On the right is the original
photo, and on the left is what happens when DOF is too narrow. The
image on the left is altered and feels wrong - the narrow DOF
his essentially makes everything look like miniatures. The next image
is of Madden NFL 08, which suffers from the same issue. The players
portray more of an action figure feel, than that of large NFL players.
An example of unnatural use of DOF. An effect referred to as tilt shift lens, simulated here in Photoshop.
Madden NFL 08 with unnatural DOF. The players and stadium feel like miniatures.
To avoid these pitfalls and get our DOF system correct we put
together a library of real world tests that we shot at NFL games.
Shooting the reference ourselves allowed us to understand exactly what
we were looking at back at the studio. Once the charts were created,
our amazing programmer Andre Pham calibrated our in-game system to
match each instance. From there he was able to generate formulas and
algorithms to drive the dynamics of the system.
Pictured is Madden senior lighter and fellow photo buff Jeff Ostergaard on one of our many research trips to NFL games.
The diagrams below show the effects of focal length and subject
distance to lens on DOF. Notice that the further away the subject is
from the lens the larger the DOF (larger area appearing in focus). In
the above chart you can see that shooting a subject that is 10 yards
away (With the same focal length) has a more narrow DOF than shooting a
subject 30 yards away.
A lens can focus at only one distance and the sharpness will
gradually falloff on both sides of the focus distance. In Madden and
NCAA this gradual falloff to the blur effect mimics what one would
expect in a real camera. In past implementations of DOF there was no
concept of varying amounts of blur.

Below you can see a study on the effects of getting the same framing
using the same f-stop, but getting two dramatically different DOF sizes
based on distance to the lens and the focal length.
Benefits:
Depth
of Field helps direct the eye - making busy and distracting shots
appear ordered. Artists often use a narrow DOF to remove the subject
from distracting background elements. Check out the following shots to
see an example of how DOF can improve an otherwise busy shot.
For years we have avoided telephoto focal lengths in our cameras -
post play especially - to avoid these very messy images. Unfortunately
a large portion of broadcast cameras are very telephoto. Now
with our DOF we can match broadcast cameras and create more visually
appealing shots in both NCAA Football 10 and Madden NFL 10.
Other Improvements Explained
Single Digit Helmet #s
We
have added the ability to center single digit #s on our helmets.
Although a small touch, I know Steeler Nation (Including myself) will
sleep well knowing Big Ben's helmet is accurate in the game. Ian was
happy that we have the Giants correctly emulating this as well.
Super Bowl Patches
Teams
will wear Super Bowl patches on their jerseys for the big game, whether
you are reliving Super Bowl XLIII or in year 30 of your franchise.
Custom Super Bowl Fields
Utilizing
the same tech as NCAA for custom bowl endzones and field art, Madden
NFL 10 features team specific end zones, midfield logos, and player
boxes that are dynamically configured whether you are reliving Super
Bowl XLIII, or in year 30 of your franchise.
Towels
Authentic
player towels are in and fully animating, complete with Wilson and NFL
Equipment logos. They can be assigned to any player, but can not be
moved to the middle of the body (unfortunately due to major clipping
issues that were occurring).
Referees on the Field
Unlike
last-gen which only had 5, we were able to get all 7 referees in to
Madden NFL 10 with AI and a full suite of avoidance (and collision)
animations.
Chain Gang on the Sidelines
Because
you see it on Sunday, the chain gang has been added back. They
dynamically move up and down the sideline giving clear indication of
the first down spot and line of scrimmage.
Steelers Don't Wear Captains Patches
And they won't in our game either. Same goes for the Cowboys.
Secondary Color Equipment
Each player will be tagged with the proper color gear. Santonio Holmes wears yellow gloves, so expect him in yellow gloves.
Better Nameplates
Since
Madden NFL 06, the letters on the back of the jerseys have all been
somewhat squished to account for longer names like Houshmanzadeh. This
has been fixed with a new dynamic sizing algorithm, so all names now
look correct.
Lastly, we saw a lot of feedback about people thinking that
Roethlisberger wasn't quite big enough. So, we made a quick pass and
tuned him up a little bit - things like shoulder pads, arms, chest,
etc. So here it is - a bigger, better "Big Ben".
I've revealed 10 Madden NFL 10 enhancements here, but there are
even more improvements in the shot that we aren't quite ready to talk
about.
As you can see we are very serious about getting to those little
details. Our feeling is that every single player is probably someone's
favorite, so if we get that character wrong in any way, the Madden
experience is less than what it could be for that fan.
Hopefully you have enjoyed reading about DOF and the other
enhancements. As Ian has said in past blogs, "Everything you see on
Sunday, see it in Madden NFL"...cameras are no exception.
Thanks for reading,
Michael Young
