Just to let everyone know, I had a better look and there was indeed Asahi Pentax S but also 1a so it's another model make later

Hi, Amin.
Yes that would be fun to try this weekend
You can use the smudge tool for that if you want to be creative

There are also other tablets but WACOM is the best I think.
The Bamboo fun is a great one to start with link
It comes in two sizes and it really depends on your way of drawing basicly, which one is best.
The biggest one (Bamboo Fun Medium) might be the most favorable though, it's just a bit more precise.
The frist 3 days you will hate it but simply lock your mouse away for a week and only use the pen

They just introduced new version of the pro level intuos so maybe if you look around you can get an intuos3 for a nice price but expect them to be still expensive though

Interesting John, I hardly do use the eraser in photos or anything other really selective, except to remove sensor dust and such.
But it surely was effective what you did and a simple solution.

Aiki, my spelling wasn't 100% correct.

Just installed gimp again so that I can explain what I did more or less.
I just tried it with and without noise reduction but without it has more clarity, it's almost the same as Galoots version, not so soft as you mine.

1. duplicate the layer named background and set the layer mode to softlight.

2. duplicate the layer with the soft light and apply filter- enhance- unsharpen mask this sharpens the photo. simply aply what you think is right.

If it's right you have in the layer window, 3 layers.
- the top one a layer in softlight mode with the unsharpen mask
- middel one a layer in softlight mode
- bottom one the orignal layer named background.

3. select the layer named back ground and go to colors- levels.
you see a new window with a diagram that looks like a hill with bleow that a beam that goes from black to white with 3 arrows.
Move the arrows on the edges to the closets feet of the "hill".
Then move the middel arrow to the left till you think the brightness of the photo is alright. press OK.

4. then with the same layer still selected go to colors- hue saturation.
now simply slide the saturation slider till you have something you like.
Press OK and that's it.

This isn't what I normally do but it did the trick with your photo. Just play around and try what works and not thats the only way to really learn it. There are more ways to rome then one so nothing is wrong or right.

Facinating if you try to see forms in them, with the second last one I got the idea of seeing a woman in it.

You need to set the flash on manual mode, then you get 1/4 1/8 etc.

This my go;

It comes close to that of Galoot but just a bit differend.

Aiki you use Gimp if I remebered correctly, I did it in photoshop but you can do almost precisely the samething. I'll download and install Gimp again when I get home since I need to go now, sorry.
I've used the things I said plus an unsharpen maks to sharpen the photo in the end but started with a noise reduction to remove those very small drops.

To summerize those discussing.
DNG that the camera make aren't really that compressed and take up twice the room as a PEF file from the camera. DNG is better supported so the best idea we came up with to do was shoot in PEF and use the Adobe DNG Converter to convert them from the card to DNG on the harddisk, since these are compressed by the computer they are even smaller then PEF.
All formats are loseless so theoreticly their won't be any lost of quality.

PSD is quite a large file and only useable when saving your photoshopped image if you want to do some photoshoping later. TIFF is the prefered file to save your photoshopped image since that's also loseless but the quality of losely compress JPGS are certainly also very good. JPGS aren't loseless so you will lose some quality with every "save" that you do, so do the processing in one go and leave it with that.

I hope that I make a good summerize here, if you want to add something please do so

Interesting shots Amin andvery sharp.
The shadow each pedal (?) leaves on to each other is very lovely in the flower shot.

Do you notice any change in the macro magnification or only that you're capable, to shoot them from a further range?
I'm actully hoping you can get closer with a TC.

There isn't an awefull lot of clout in there except the rainbow and the grass, maybe playing with the saturation and vibrance might get you the result.

Somtimes duplicating a the layer of the photo and seth the payer option to softlight can do some wonders, you can stack them as much as you like to get a greater effect and use the opacity of the layer to fine tune it.
I'm not behind the right PC so I can't play with it, sorry

Yes bad hair day would be a nice title.
like Alan said brighten them up a bit to make them more vibrant.
