Indlela yokudweba itshe ngepensela isinyathelo ngesinyathelo
Amatshe amaningi angangeza isithakazelo kunoma iyiphi indawo endaweni. Kunezinhlobo ezahlukene zamatshe: i-sandstone, shale, i-limestone, amatshe entaba-mlilo, amatshe. Lesi sifundo sizocacisa kakhulu futhi sizobe sifunda itshe eduze.
Izinto ezidingekayo: F (leli penseli liphakathi kwe-HB ne-B) kanye no-2B 0,5 amapensela emishini, amapensela e-4H kanye ne-2H, i-Blu-Tack noma i-nag, i-eraser kagesi, i-Strathmore 300 Series Bristol Board iphepha elibushelelezi.
Sketch. Ungalokothi ubukele phansi amandla omdwebo. Angivamile nje ukuhlala ngibuke i-TV, kodwa uma ngikwenza, ngithatha ifolda yezithombe kanye nomdwebo. Nasi umdwebo ovela kuleli qembu.
Ukudala umthamo kanye nefomu.
Uma uwabuka nje, kubonakala sengathi kulula ukuwadweba. Ngithola ukuthi ziyinkimbinkimbi kakhulu kunalokho. Kumele abe nomthamo kanye nokuma. Ukukhanya nesithunzi kudlala isici esibalulekile ekudwebeni amatshe angokoqobo. Ngicabanga ukuthi ukuqhathanisa okungcono kakhulu yikhiyubhu. Ukuze udale lesi simo se-XNUMXD, sidinga ukusebenzisa ukukhanya nesithunzi. Ingaphezulu lekhiyubhu elinokukhanya kwelanga okuqondile kakhulu likhanya kakhulu. Uma uthi nhlá kungase kubonakale sengathi amatshe kulula ukudweba. Kubonakala kimi ukuthi lokhu akulona iqiniso ngokuphelele - kufanele babe nevolumu nokuma. Ukukhanya nethunzi kudlala indima ebalulekile ekuboniseni amatshe angokoqobo. 
Lo mdwebo ubonisa amadwala, abonisa ama-engeli nezindiza zawo, nokukhanya ekhoneni eliphezulu kwesokudla kucatshangelwe. 
Lo mdwebo ubonisa amatshe anamakhona athambile, kodwa izindiza ezenza isimo se-three-dimensional yamadwala zisabonakala.
Izifundo eziningi zokudweba ama-rock ziyama kuleli phuzu. Ingabe bayobukeka endaweni engokoqobo? Kukhona amathoni ambalwa kanye nemininingwane. Sibheka isithombe. Isithombe sikhonjiswa ngombala nomnyama nomhlophe. Ngiyathanda ukudweba nokufunda ngokusebenzisa izithombe ezimbili. I-Grayscale isiza ukuthola amathoni, kuyilapho umbala usiza emininingwaneni.
ISINYATHELO 1. Sizodweba itshe elikhulu kwesokunxele. Ngiqala ukudweba idwala ezindaweni ezimnyama ngepensela engu-2B. Izindawo ezikhanyayo zidwetshwe ngepensela F. Ngisebenzisa amamaki amafushane angahleliwe, ngigxila kumanotshi nasezindaweni ezinomthunzi. Bheka, kufanele udwebe zonke izindawo ezimnyama zetshe kulesi sinyathelo.
Isinyathelo sesi-2 Uma usunayo yonke imininingwane yokuqala edwetshiwe, thatha i-collet ene-bevelled bese usebenzisa imivimbo ibe ungqimba olubushelelezi, olulinganayo phezu kwendawo yonke. Ezindaweni ezilula ngisebenzisa i-4H ne-2H ezindaweni ezimnyama. Qaphela ukukhanya ezindizeni nasemakhoneni.
ISINYATHELO 3. Manje ubumnandi sebuqala! Ngepensela elithambile elinomshini, siqala ukwenza ukuthungwa! Ngisebenzisa amamaki amafushane angahleliwe ukuze ngidale imigodi nendawo emangelengele. Sebenzisa ipensela elithambile phezu kweliqinile. Siyazi ukuthi ipensela elithambile phezu kweliqinile lakha indawo engalingani kakhulu. Kodwa yenza izimanga ngokudala ukuthungwa okungahleliwe, okumangelengele kwamadwala. inikeza i-stroke ebanzi eyisicaba. Siyaqhubeka nokudweba zonke izendlalelo ezintsha. Sebenzisa i-Blu-Tack (nag) ukuze udale izingxenye ezincane. Sebenzisa irabha likagesi ukuze udale amabalanyana okukhanya. Ngishilo esinyathelweni 1, kufanele uqiniseke ukuthi umaka zonke izindawo ezimnyama zamatshe ngaphambi kokudlulela esinyathelweni sesi-2. Isizathu siwukuthi uma udwebe imigqa ngepensela eqinile, ngeke ukwazi ukufeza. amathoni amnyama kule ndawo.
Inketho elungile.
