This week’s question is from the forum: 


Hello Steve,


I'd like to know if there are any quality keyboard with both English and Thai lettering on them available in Thailand.

Something like the Logitech Revolution or similar.

The reason being is that my wife's Thai and uses  Thai script to chat with her family & friends who live in Thailand.

And I don't want to go through the hassle of having 2 keyboards, one for me and the other for her.




Charles -


This is a good question.  I haven't specifically looked for Thai script on keyboards in Thailand but I have noticed certain models.  For the most part keyboards that come part of complete systems sold in Thailand have both Thai and English script.. but after market keyboards sold outside a system all seem to have English only with the exception of the locally sold really cheap quality keyboards which have Thai script.   I can tell you for sure Logitech products sold in Thailand do not have Thai script.


As an alternative you might want to consider an inexpensive (300-400 baht) Thai corded keyboard, and a  quality cordless in English. 


Btw -  The Logitech K800 illuminated cordless.. is really nice.



And one more from the forum:



Hello Steve,


I have a question for you!


In Lightroom 3 when I open my raw files from my Nikon D80 with  the Sigma 18 >125mm, I have a large range of Sigma profiles to choose from has can be seen from the fisrt screen shot. But if I open a tif file I can only choose from a few different profiles and the one I use; being the Sigma 18 >125mm is missing and the closest one that I can choose is the Sigma 18 >200mm, has can be seem from the second screen shot.


Can you tell me what is going on!


Also I have noticed that there is no profiles for any Tokina Lens, do you know where I can find some? Are they available?





My Response


Hi Charles -


First, we must understand that profiles come from two places.


1.  Adobe.

2.  Users.


Also, we need to know that for the vast majority of users, by the time a file becomes a TIFF, we are long past the raw correction phase.


1.  Adobe creates 'standard' lens profiles for lenses they support.  This includes almost all of the original manufacturers lenses such as Canon or Nikon, but only a select few from other manufacturers like Sigma or Tokina.   Adobe doesn't feel enough people who use these lenses uses their product to make it worth the effort.


2.  Users now (since Ver 3.1) have the capability to create their own profiles and further, they have the option to share them via Adobe's profile sharing.


Since most users process in RAW it would make sense there will be substantially more profiles created for RAW use than for TIFF use.


This can be confusing because traditionally in Photoshop we process tiff files, and lens corrections have traditionally been performed on tiff files.  However, once Adobe made the capability for lens correction available in ACR (Adobe Camera RAW) and Lightroom, we now have the much better option of correcting for lenses during the raw process.  So that's where most are doing it now.


And.. Lightoom has never been a "tiff editor" in the same way Photoshop has.  Lightroom 'can' edit tiff's and jpegs, but it's really mostly used as a RAW editor and as a cataloger for all file types.  So.. no one would be applying lens corrections of tiffs because no one would capture in tiffs when there are so many reasons capturing in RAW is a better choice.


I hope this helps.




Another forum user responds:


Wouldn't you have to use the lens profiles on the original images, before processing them in HDRs ? And same if you were using photomerge to make a panorama ? You would want to fix any lens distortion first, wouldn't you ?

The OP responds:


You are correct, but this takes more time and it’s this extra time that I have very little off at the moment.


But I am working on a solution to the lens distortion issue with tif files at the moment and hopefully this will not be an issue soon.


Also I use PTGui Pro version 8.3 to make panoramas and I get great results using the raw files to make the panoramas, has this program supports raw files.


You have to understand that when I shoot a panorama set there might be up to 20 files, so if I had to edit each one before making the panorama this would take me a certain amount of time!


"Free Time" that at this point in my life I have very little off due to family and work commitments, so if I can use one program instead of 2 or 3 to do all the work for me I use that program.


My Response:


You might want to consider using the copy&paste feature of Lightroom to transfer the settings/changes you make to one image, to as many as you want.  Develop/copy settings         Develop/paste settings    Of  Sync Setting.


There are many ways to save time in Lightroom.. When you consider the image quality improvements from processing in raw over a tif or jpeg.. even lens corrections should be done in raw.


Try this:  Write down in groups settings you apply to every image:


a.  Sharpening

b.  Clarity

c.  Profile (landscape, portrait, embedded, etc)

d.  Lens correction


And then settings you might want to change for a group of images taken at the same time of the same thing:


a.  White balance

b.  Exposure

c.  Noise reduction

d.  Saturation

e.  Fill light  (you should rarely need this one)

f.  Blacks  (you shoudl rarely need this one too)

g.  Vibrance (again, rarely)

h.  Recovery

i.  cropping



And then the settings you must change per individual image:


a.  Spot healing

b.  Localized editing

c.  Red eye repair

d.  Graduated filter



Then, adjust the first one in the first group, apply to all from the session via sync.


Then, adjust the first one in each group from the second group, apply to all via sync or copy&paste settings.


Then.. adjust each individual image.


Obviously there will be times individual adjustments from the groups above will fit into the different groups.. it depends on the shoot.  But you get the idea.


Lightroom is optimized to save the professional photographer the most time possible and it does it better than anything else out there.  And frankly, these methods are easy enough for anyone to learn in less than 5 minutes.


This is a good rule of thumb:  Anything adjustment you make in Lightroom should be made to a raw image.  Anything you need to export to Lightroom for HDR, Photoshop, Ptgui, etc, etc.. should be done via Tiffs.  It's very rare (but it happens) you'd be better off doing an adjustment in Lightroom on a tiff you've already processed in another program.  However, I always re-import all my completed tiff's back into Lightroom to database and distribute as needed..




The OP’s last response:


Thank you Mike_N & Steve.


I am already doing most of the things that you have listed here!

But after the image has been processed.


So last night realised that it wouldn’t take much to make a new standard profile for the Sigma 18-125mm lens that has only Lens Correction. So I had a go a few sets of Panoramas, and HDR’s and they are much better.


But when I tried the following: a. Sharpening b. Clarity c. Profile (landscape) d. Lens correction , they improved even more.


Now the only delima I have is to go and re-do all my Panorama's & HDR photos with this setup.

A "PAIN" but the rewards will be worth it.

This is what a HDR looks like now, the left image is the original HDR and the right image is the image is where;


a.   Sharpening b. Clarity c. Profile (landscape) d. Lens correction , have been added to the original raw file before being processed in the HDR program.

Once again thank you.


This is why Steve created these forums for!


Where ordinary people like me can talk about the problems we face in photography and get ideas on how to improve our technique or work flow.
