Photomatix Pro from HDRsoft is a stand alone application that allows you to use multiple bracketed exposures to create a single High Dynamic Range (HDR) image. This can be achieved in Photoshop CS3 but not as easily, or with the same amount of control, that Photomatix provides. As well as being able to blend multiple exposures you can also use Tone Mapping to pull out amazing shadow detail from either multiple exposures or from a single image. I use a combination of Lightroom and Photoshop CS3 to post process my work but have found that Photomatix has added a new dimension to many of the images.

PHOTOMATIX PRO HDR SOFTWARE REVIEW Tone Mapping Multiple Images The three bracketed exposures on the left have been combined using Photomatix to produce a single HDR image. (Mouse over the large image for a more detailed view) HDR images have much more detail in the bright and dark areas but will not display correctly on a monitor. Photomatix processes the HDR so you can display or print it. You can also create a pseudo-HDR image from a single RAW file. This method can achieve very good results and often brings out far more detail than can be obtained by the RAW processing software itself.

Photomatix Pro User Interface Images are imported into Photonatix using the Generate HDR menu item which then produces a single HDR image. You then select Tone Map. The interface then allows a variety of parameters to be changed to produce you final image. Details Enhancer: takes into account whether it is in a bright or dark area and maps it accordingly. This is the default mode and the one which has been my preferred option. Tone Compressor: Ignores the local brightness context of the image and compresses the whole image into the 0-256 range of an 8 bit monitor. Tone Compressor: Ignores the local brightness context of the image and compresses the whole image into the 0-256 range of an 8 bit monitor. Strength: controls the amount (strength) of the contrast enhancement. Color Saturation: Controls the intensity of the color. Light Smoothing: Controls the compression of the tonal range which in turn affects the global luminosity level. Keeping the slider on the left will give you a more natural look whilst moving it to the right will boost shadow and brighten the image. Color Saturation: Controls the intensity of the color.

Keeping the slider on the left will give you a more natural look whilst moving it to the right will boost shadow and brighten the image. You can see the effects visually via the histogram but the visual feedback via the preview widow is more effective. Sub menus take you to Tone, Color, Micro and S/H (shadows highlights) adjustments. These control color temperature, saturation highlights etc. Micro Adjustments allow the fine control of local detail and noise reduction.

These control color temperature, saturation highlights etc. Micro Adjustments allow the fine control of local detail and noise reduction. The working area can be resized and an inspection loupe is provided to allow an much more precise view of the effect of each of the adjustments. You can save your settings as a preset and then you apply (process) the the image. The output can be a 8 bit JPG or 16 bit TIFF file. Note if you saved the HDR image prior to Tone Mapping you can easily go back and try different settings. You can save your settings as a preset and then you apply (process) the the image.

There is much more to Photomatix including batch mode operation and the individual processing of RAW to optimize dynamic range. I am still learning how to use this powerful application but have obtained images that I did not think were possible. Keeping the final image as natural looking and believable is important, although you may be after a specific HDR effect in which case a natural look may not be what you want. I thoroughly recommend this product as a vital part of your digital imaging workflow. Photomatix Pro is currently at version 3.0 is available for both Mac and Windows and costs $99.

Photomatix program za izradu HDR snimaka Photomatix Pro proizvod je tvrke HDRsoft, a predstavlja samostalnu aplikaciju koja nam omogućuje da koristimo nekoliko snimaka različitih ekspozicija za dobivanje jedinstvene High Dynamic Range (HDR) slike. HDR se jednostavno može prevesti kao slika sa velikim dinamičkim rasponom. HDR snimke možemo raditi i u Adobe Photoshopu CS3, no osim što je PS primjetno skuplja aplikacija od Photomatixa, također je i zahtijevni što se tiće resursa, a i potrebno je uložiti puno više truda i znanja da bi dobili rezultate jednake onima iz Photomatixa. Photomatixov ključni dodatak je skoro pa savršena akcija, Tone Mapping, kojom možemo izvući zapanjujuće detalje iz sjena bilo da se radi o snimkama različitih ekspozicija ili samo jedne. HDR slike imaju mnogo više detalja u svijetlim i tamnim područjima, od slika jedne ekspozicije, no, one se neće pravilno prikazivati na monitoru. Photomatix obrađuje HDR tako da ga možete prikazati na monitoru ili ga jednostavno ispisati. Također možemo stvoriti pseudo-HDR iz jedne RAW snimke. Ova metoda može postići vrlo dobre rezultate, a često dovodi do puno više detalja nego što se mogu dobiti obradom RAW snimke u raznim aplikacijama za obradu RAW snimaka. Slike se uvoze u Photomatix koristeći Generate HDR (Generiraj HDR) stavku izbornika, koji zatim proizvodi jednu HDR sliku. Zatim odabiremo Ton Mapping. Sučelje koje nam omogućava “fine tunning” raznih parametara kojima onda dobivamo traženu HDR snimku. Dobivanje HDR snimke u par korakata koristeći Photomatix Pro aplikaciju. Korak 1 – fotografiranje Za dobivanje dobre HDR snimke potrebno je snimiti nekoliko snimaka različitih ekspozicija. Nepisano pravilo govori da je potrebno najmanje 3 snimke, pod-eksponirana, normalna i pre-eksponirana snimka. Gornja granica broja snimaka ne postoji. Većina DSLR fotoaparata ima opciju Bracketing. Tom opcijom aparatu zadajemo korak ekspozicije između snimaka. Preporučljivo je uzeti vrijednost +/-2. Također fotoaparat stavljamo u mod A, odnosno prioritet otvora bledne te način snimanja stavljamo u Continuous mode, pritom aparat jednim pritiskom okidača bilježi više snimaka. Time izbjegavamo mogućnosti pomaka aparata. Naravno, korištenje stalka, tripoda je obavezno. Korak 2 – učitavanje različito eksponiranih fotografija Najjednostavniji način za učitavanje fotografija je odabir datoteka Finderom (Explorerom) i povlačimo ih na Photomatix ikonu na našem Docku (Desktopu). Potom ćemo dobiti dijalog koji će nas pitati što želimo učiniti s datotekama. Odabiremo opciju Generate an HDR image i klikamo na OK. Sljedeći prozor ispisuje odabrane datoteke. Ako je potrebno, možemo ukloniti datoteke ili odabrati druge. Osim ovog načina, možemo izravno pristupiti dijaloškom okviru za odabir izvora slike bilo klikom na ikonu Create HDR image na Workflow panelu, ili klikom na Process menu i odabirom Generate HDR. Korak 3 – generiranje HDR snimke Sljedeći prozor nam omogućuje da odredimo opcije za kreiranje HDR slike. Tri fotografije su snimljene koristeći stalak, tronožac. Još uvijek provjerimo poravnanje istih klikom na Align source images opciju za ispravljanje poravnanje za male pomake koji mogu nastati iako koristimo stativ. Nakon klika na OK gumb, Photomatix će različito eksponirane fotografije stopiti u jednu HDR snimku koja predstavlja potpuni tonski spektar boja u jednoj slici. Korak 4 – priprema HDR snimke za prikaz Ono što prvo primjećujemo je da generirana HDR slika izgleda razočaravajuće. To je zato što većina ekrana ne može pravilno prikazati zastupljenu boju i informaciju na slici bez daljnje obrade. Neobrađena HDR slika je na neki način slična negativu filma ili RAW datoteci kod digitalnog fotoaparata. Ona zahtijeva daljnu obradu za prikaz na ekranu ili ispis na neki medij. Ta obrada se naziva Tone mapping. Tone mapping otkriva detalje u sjenama koju su sadržani u izvornoj HDR slici te ih naglašava. Tone mapping pretvara HDR slike koja se izvorno nalaze u 32 bita/kanalu u neku sliku od 16 ili 8 bita/kanalu te na taj način mogu biti spremljene kao TIFF ili JPEG datoteke. Korak 5 – tone mapping Tone Mapping postavke na paleti nam omogućavaju podešavanje detalja i odabira tona boja na dva načina: prvi je Details Enhancer metoda, a drugi Tone Compressor metoda. Kako sad već vidimo “živu” HDR snimku, malim pomacima u postavkama dobivamo baš onu traženu. Osnovni orijentir za isparavno podešavanje snimke je naše oko. Važno je napomenuti da je pregled približan – konačni rezultati se mogu neznatno razlikovati u slučaju Enhancer tone mapping metode.
