Bob,

Great new project. Even without the sign it is an interesting building.

Some good information here on sign-making. I'm still pretty gimpy using Gimp.

Bob, Ted, Dave, I just emailed Dr Ken, whose photo of the same sign is in the link that Ted posted late last night. That image is really low resolution and I think it would fall apart even at HO scale, let alone larger, so I asked if he'd send me a higher resolution copy that I could then redo like the one I posted yesterday.

I also asked him what the three thin vertical white lines running from the top of the building to the ground are. Yesterday i thought they were part of some grid someone had superimposed on the image to help square it up or scale it, but if you look at Dr Ken's photo thatTed linked to, the "lines" are still there and they appear to be something attached to the building. I plan to remove them from the sign, like I did on the first two copies above, but want to know what they might be - any ideas?

I'll let you know when he replies.

Ted, Rather than me rambling on & on, here is the nutshell version of making wall sized decals. For those already familiar with image manipulation software, this might be enough to get you going. For everyone else, ask about specific areas that are not clear and I'll add more info.

1. Take photo of wall you want to use as straight on as possible.

2. Open photo with GIMP (or Photoshop or similar program).

3. Overlay a grid as a separate layer, size of squares can be pretty much anything you want in pixels, mm, cm, in, ft and more.

4.Using GIMP's perspective tool, square up the walls (the tool allows you to easily click and drag corners of the photo to stretch them so you can align them with the grid and so straighten out the distortion in the original photo.

5. Scale the photo to the full size you need using the GIMP scale tool. (Note that the default setting for this GIMP tool stretches or squeezes the image either in width or height only as you click and drag the sides of the photo out or in. But if you click a tiny box that says "Keep Aspect Ratio" then the tool will stretch or squeeze both the width and height together, preserving their original proportions, when you click and drag on the corners of the photo.
You can measure the size of the image using the grid you set up or with a measuring tool or with the rulers on the top and left side of the image. If you know the actual size of the building, you can enlarge or reduce it to your scale, or if you are freelancing a building, you can make the photo fit whatever size you need.

6. Print a test version of your GIMPed photo on plain paper to see if the size and proportions are what you need, adjust as needed.

7. Several options for final print:
A. Print on thin paper and apply to model as many how-to's describe.
B. Print on clear decal paper with Alps or similar printer that can print white (There is a German company now making white toner for laser printers!!)
C. Paint model wall a whitish color. Print decal on clear paper with inkjet or laser printer. Clear coat as needed. Apply to model.
D. Print on white decal paper. Apply to model wall. Weather if needed to tone down the white.

(The walls for the NEB&W were done before my time. They basically followed the description above and were printed with an Alps Printer on clear decal paper).

Besides looking like a nice old wall sign, I loved Uneeda Biscuits. They were my all time favorite
crackers and I almost cried when they were discontinued.

For those of you that are not Gimpers (I include myself)as Bill Gill is, I have used a neat little
program for years. It is called PHOTOGRAM, you can find it by Googling it. You simply open a photo
that is skewed (not taken straight on). click the cursor at each corner of the sign or building and
BAM, automatically it produces a straightened out version you can save.

I'll look for an example tomorrow.

Bob

Thanks very much Bill, for the well explained process, and thank you again for sending me the adjusted signs'. I very much appreciate you taking the time to do so'.
You are indeed a true asset to the forum'..

Bob, I miss the Uneeda's too. Shame'..Some things should not go away'..
I will try GIMP again and also, Photogram'... Going to be a busy Friday night'...

The real title of that program is "CAD-KAS photogrammetric image rectification". How's that for a mouth full?

Anyway, this is a quicky and I should do it over to get it a little better, but time is short.




On the left is a file opened. You click on the upper left corner and then on the upper right,
the lower right, then lower left, and back to the first click to complete the rectangle. The
program immediately makes that a true rectangle and thus straightens out the sign. shown on the right.
I missed the upper right by a bit. You can then save it.

I'm going to call it "done" on printing that wall and try to get on with the project. I have to
thank Ted for finding a better photo, Ken Jones for permission to use it, and Bill for all his
magic tweaking with GIMP.

I will print that wall on self-sticking vinyl, apply it to foam core, and then cut it out. My
model will be on flat ground so I will not have the sloping foundation, just a small straight
one. I will cut out the window and build a new one recessed and a new lintel to a 3-D effect. I
will use painted styrene to make the caps on the steps at the top. The edges and the backside
above the roof line will be covered with bricks printed on the same vinyl. You can find free
brick sheets at several "texture" sites, design your own at http://paperbrick.co.uk/, or buy
some. I used TX06 Aged Red Brick from Scalescenes.com. They have many kinds and when
you buy one at a reasonable price, the ability to print as many sheets as you need comes with it.

Good Morning Bob,
Nice tip on the PHOTOGRAM. I'm trying to use GIMP but a backup is always helpful.
Every time I follow your post I learn a new technique.
THANK YOU FOR POSTING YOU PROJECTS!!
Dave

Thanks Mark and Dave.

Moving on here, you will see that this structure had four walls dividing the building into 3 bays.
The one wall has a stepped top and is the one with the painted signs we have discussed. The other
three walls are simply cut from foam core, peaked without the "steps". They are covered with the
brick sheet above the roof line and caped with styrene. I set them aside to work on the front wall.



Those three front sections are basically the same so I isolated one and will make a master from styrene and cast three in resin.




I have decided that to make applying brick sheets and painting these walls, it would be easier to
make two parts. One will be the whole wall without the window frames and shutters and of
course, the other will be those window frames and shutters.

My first piece is to establish the outside dimensions of the section and the locations of
the windows and doorways. When I glue this to a backing sheet, the backing sheet will represent
the level of window "glass" and I will use styrene strips to build up detail from that.



Bob

Wow, Bob, I sure could have used this program over the past few years'. Thanks so much for sharing this'. As Dave said, we learn new techniques and fantastic shortcuts and tips from your posts that are very beneficial and helpful to us. I'm very happy to hear that you liked that website and the photo of your build'... Nice for a change to be of a
help to you'...
